Hi there,
I was searching the forums for an RS-232 for serial access and can't find any information as I was wondering if there is a RS-232 cable avaiable for serial access. Like the cables RS-232 to USB converter for laptops to config cisco, juipters and Huawei. I have a RS-232 to USB but it is using a regular USB A plug. So the other question is that is possible to use the regual RS-232 to USB converter with gender change, but I don't think there are any drivers for the accessory for WM6. So it sounds like I have answered my own question . BTW, I am using the Kasier and it would be a great help if I can buy one instead of DIY one like -> http://forum.xda-developers.com/showthread.php?t=257858
Kengie
would believe it is required for such a device to work that the pda support usb host only Athena does that
Thanks. I though that the Kasier has the OTG (yes it does), but you are right. It doesn't support the USB Host features. Thanks.
if you by OTG mean usb on the go then htc dont seem to use that feature in any of their devices even if the cpu have it included it seems they use their own usb chip

Well guys,i am going (me and other guys who have good experience in e-circuits)to try build a USB port to the Himalaya..
Now I understand by the http://wiki.xda-developers.com/wiki/Connectors link that only the large connector have the pins for USB..
During this time,any help,new informations about himalaya's USB will be appreciated.
In fact the project "USB port" is actually at level zero. (really busy previous week)
I am trying to make this to connect especially a Mouse to XDA2
So,I really need a help from you,MattM and others..
Can someone build or convert a generic windows mouse driver to pocket pc?
Or maybe is more easy to make a serial connector for mouse?
Then does we need a pointer?
-Is this factible? or just a dream?
(Laucher Prog based on Flash like PocketWin has a Pointer add-on)
Waiting for your replyes!
Regards,Ser
i read something about it in this forum, try searching for home made keyboard or mouse & you might find some answers to the basic questions
Come on guys!
I will use the DC adapter connector and USB female connector.(You can see the photos attached)
-But first explain me closely about UDC- and UDC+ does they are for data transmission or power?
Also USB_VDD is for?
-If I connect a USB device to the XDA2 does it will give power to it?(for mouse,etc..) or do I need to connect an external power alimentation? If yes,6V?
-If I build a Serial port can you explain more about:
RS232_DCD
RS232_CTS
RS232_TXD
RS232_RTS
RS232_RXD
RS232_DTR
Maybe is simply make the serial cable like on the "Connector's Page" (http://wiki.xda-developers.com/wiki/Connectors) and attach a serial Female-Female to connect Mouses and others?
Please post your comments,suggestions,ideas.
Regards,Ser.
UDC- and UDC+ are data
USB_VDD is for power
I don't think anyone yet knows if the XDAII can work as a USB host anyway.
For rs232 you will normally only need RS232_RXD, RS232_TXD and ground.
I'm sure someone did a serial mouse program before....
Jamie
RS232_RXD, RS232_TXD are for data?
I hope someone did the program but i've searched over i-net and didn't find anything about it!
I've also read about the built-in USB port of Toshiba,some people connected their HDD and all went perfectly.
So,I hope connect a mouse will not be so hard..
Regards
Have a look here for a mouse driver http://www.windowsfordevices.com/articles/AT3401319437.html
Yeah,i've seen it before but don't sure if it will function properly,but let's take it for that moment.
Thanx!
After a short search over i-net I found the prog. that uses Toshiba for its serial devices like mouse,keyboards: Click n'type and Point n'type..let's figure more about.
OK,now I will connect the female usb to the connector like:
RED (USB_VDD +5V) to Pin 13
GREEN (UDC+) to pin 14
GOLD (UDC-) to pin 15
BLUE (GROUND) to pin 16
Correct me if it isn't.
But I can't find a scheme of the connector that I will use,I can't understand which is the pin 1..2..
Can someone give me help about?
Thanx to RUDEGAR that provided me the link,http://www.deje.gmxhome.de/software.html
I have the USB drivers and pointer for Mouse,also support for Mass storage.
i have disambled this connector 2 times
let me look it up for you
[UPSIDE]
[1] [5] [9] [13] [17] [21]
[3] [7] [11] [15] [19]
---------------------------------
[4] [8] [12] [16] [20]
[2] [6] [10] [14] [18] [22]
[DOWNSIDE]
now the upside is when you hold the connector flat and you see the 2 cutout lines in the plastic wich goes into the xda
topleft from that is pin 1
Well,the cable doesn't work! :x
-XDA2 does not give power to the usb device (tryed with a optical mouse)
(N:we verified with a VoltMeter and all cables seems to be ok)
-Also the DeJe Drivers (originally built to Toshiba) don't work. But the driver's are compatible with all WM2003 OS..
-I verified that on my pc(Win XP) when I connect the Optical mouse,it will no give power to the device once it load the drivers,so I guess maybe the same on Pocket Pc?
What do you think about?
-Probably I will build a Serial Cable for the Mouse
Regards, Ser
have you tryed a usb pen yet.. I see you mentioned storage before
yes,in fact I have't installed the Mass storage drivers for a Pen Drive,etc..
But I verified that no led (on pen drive) and no optical light was lightening so is easy to understand that XDA2 don't gives power to the USB devices... :?:
would they light anyway ? do they only light when the correct drivers are used and its told to light. I think it would be a awesome idea to add usb to the xda.. you could then use it for loads of other things..

It cannot work. Never will.
There are two different types of USB devices: hosts and clients. You can only ever connect a client to a host. Connecting client to client does not work. It's a bit like two people picking up the phone, none of them dialing a number, but still hoping they'd get connected. Not going to happen.
All USB mice are USB clients. The XDA II also is a USB client. The USB chip in the XDA II can only handle being a client. It does not support host mode, so no software in the world can change the XDA II to a USB host.
So, connecting a USB client to an XDA II will never work.
For serial communication (RS232), there is no such problem, so it may be possible to connect a serial mouse to the XDA II. The first thing you have to make sure is that the voltage is correct. "Normal" RS232 uses +12V/-12V, whereas most small devices (and quite likely also the XDA II) uses 0V/5V. You may have to add a MAX232 (or compatible) level shifter chip to your cable.
I strongly suggest you search the 'net for RS232 and read as much as you can find. If you just experiment with cables without really understanding the implications, you might damage your XDA II.
Once you sorted that out, make sure you connect all the handshake lines your mouse uses. I would imagine that some mice may need at least the DTR line assigned before they will start doing anything.
After that, the rest is software. Your driver will have to a) pick the correct baud rate, b) drive the handshake lines correctly, and then c) it can start receiving data.
Good luck!

well there are CF cards which have usb master support
and with the backpack the xda2 can use CF cards
of cause the driver issue could be troublesome and i'm
not sure about the speed dec going that interface to interface way
but i would not rule out that it could work
with the right drivers mind you
How about connecting a serial to USB convertor to the serial port on the XDA II?, surely that would leave you with a USB host port that you could plug a mouse into?
In this case is more simple to connect serial mouse to the serial port.
Dunno if how u tell the usb will work.. :?:
http://www.expansys-usa.com/product.asp?code=113389
Would this do the trick?
It says host ports, can the XDA2 handle it?
Hi
i am sure for alot of people out they have searched for something to make their usb devices work on a pocket PC. i have gathered some information with regard to this topic and i hope that other users will add to it so that there is a greater awareness and mayb it will help someone figure out the best way to create 1 for the PPC
right now the there is no external USB host controller for pocket pc.
the reason we need the USB host is so that we can connect external USB devices. but i believe that we also need to load the drivers for devices as well.
wat i think is the way the device should work is the usb host for ppc should have drivers built into it so that when u connect a flash drive for example it can identify it and then send the necessary info into the PPC so that the PPC will then handle it in the correct manner. thereafter on the PPC we will probably find it as an additional drive.
I think that connectivity will actually work via the SDIO and not via the USB port.
If there are any other senior members that can elaborate on this it will be great, it will shed some more light on this feature.
I personally would love to have this feature, not for any specific external device but just the ability to have interoperability with all my usb devices onto my PPC.

there are usb host CF cards i believe
not sure if anybody ever made to test in a himalaya backpack which have a CF card
thing with usb devices is that usb mass storage one 1 generic driver
so one for external hd's sdreaders and usb keyring would be enough
CF USB host
Hi
http://www.ratocsystems.com/english/products/subpages/cfu1u.html
do you think that it can be converted from CF to SDIO ?
I actually searched for a CF to SDIO converte but no luck, however even if i do find it what are the chance that it will even work!!
anybody knows more about this ?
reo
it could easy brake because of the size diff
another problem is it would require 2.5watt to power a usb host
not sure if the sd interface can provide that kinda power at all
ok, but considering that we can overlook these obstacles will the converter actually allow for the CF USB to work ?
do you no where i can find a CF to SDIO converter ?

I've got a question about "USB Host" as well... I read somewhere, that some processors are capable of USB Host but the companies didn't do the wiring in their devices. and of course the drivers are missing in Win CE.
So my question is: Can I connect USB-Devices to my PDA if I build a USB-wire where I inject 5V from outside and run linux on my device with USB-support built in the kernel?
Does anyone tried this Program?

Just found it by accident and don't have a fitting cable
It's look like a fake, because: http://htc-unexisting-model.handster.com/product.php?id=3339

On the Teksoft homepage there's a driver for bluetooth input too, seems to work in the demo videos?

Has anyone tried this and found it to work / not work.
I want to connect a Leica Total Station (Surveying Equipment) (http://www.leica-geosystems.com/uk/en/lgs_67104.htm) to my Blackstone and use the Leica "Pocket Instrument Explorer" to get the two talking to each other.
On the PC the computer and instrument are connected with a Prolific USB-Serial Converter cable on a standard male Type A USB.
I have a USB Type A to USB Minin converter to physically connnect the Blackstone to Instrument. The software (which, has installed fine and seems to work) has all sorts of settings for COM3 and COM4.
I know that the USB on the Blackstone is not a HOST but I suspect that this is the case on many PDAs and if the case I see no reason why Leica would develope the software if there is not a way to connect them.
Anyone who wants to try this will need the PIE software which is a locked download for Leica Members. I will email a copy to you if desired but do not want to post it here for general distribution.
Hi
Can someone answer if USB OTG is supported on the One V
using stock kernel and ROM?
Regards
max
EDIT: After some searching I found that "official" it is not suported
What surprises me is that in the kernel configuration of the stock
kernel all options are set that I would assume to allow OTG
e.g. there is something like
...
CONFIG_USB_MSM_OTG:
Enable this to support the USB OTG transceiver on MSM chips
...
Would be nice if someone could enable this for One V. This kernel project is enabling OTG for One X http://forum.xda-developers.com/showthread.php?t=1640532
Otg only works in bootloader....

Isn't it the same?
USB On-The-Go, often abbreviated USB OTG, is a specification that allows USB devices such as digital audio players or mobile phones to act as a host allowing a USB flash drive, mouse, or keyboard to be attached and also connecting USB peripherals directly for communication purposes among them.

USB-OTG also means that you dont necessarily need a powered hub to use it AFAIK
And USB-OTG means that "both sides" can act as a client or a host
From your link above
...
USB OTG defines two roles of devices: OTG A-device and OTG B-device. This terminology defines which side supplies power to the link, and which is initially the host. The OTG A-device is a power supplier, and an OTG B-device is a power consumer. The default link configuration is that A-device act as USB Host and B-device is a USB peripheral. The host and peripheral modes may be exchanged later by using HNP. Because every OTG controller supports both roles, they are often called "Dual-Role" controllers rather than "OTG controllers"
...
Whereas USB-Host means that the android device is always the host
Since the HTC is not providing power on its USB port you always
need to use a powered usb hub in this case.
I am pretty sure that we can have USB-Host on the V since other devices
using exactly the same chipset can do it. But I still need to do some investigation
regards
max
Hi Guys
See attached screenshot and notice the "mouse pointer"
So it means we will have USB host support!
Actually not much was "missing" the guys at HTC just
"forgot" to register the usb host driver on init
At the moment the "mode" musst be switched manually
between "host" and "peripheral" which means e.g. charger a.s.o
The automatic switch based on using a OTG cable is not working
or I have the wrong cable
SO I was able to connect a active hub with a mouse and it works
Next thing will be a usb storage device
I will still need some more time to finalize this.
This will then continue in the Titanium-KISS kernel thread

max
Lol why do you have an app for screen shots?

Just a short update
-OTG cable detect working
that means switching between host and peripheral (normal) mode works
automatically. No need for a script anymore
-USB keyboard tested and works
-USB storage is still killing me

I tried connecting a USB keyboard using an USB OTG cable, but I didn't get it to work. The other USB port is in use by my external harddrive.
Is there a possibility to make the keyboard work?
Can immagine more people want to add a second USB device to their OUYA...

You'll need to buy a USB HUB (Get a powered one to future proof all your USB needs, you can get a USB 2.0 Hub pretty cheap). This will allow you to hook up at least 3 USB's to the OUYA. The Micro USB won't work for things such as hard drives or HID devices.
In the future, please use the search function before posting as this has been talked about in many other posts.

I have a 4-port hub and it works fine connecting 1 storage and 3 other usb devices
I had this issue where only one harddrive could be used and If you have a harddrive with 2 partitions ouya wont mount it. Luckily I found an app called usbotghelper which does all the above I mentioned plus read and write and ext3 support. I wish it would get submitted to the ouya store so I could use the paid version that will mount on startup.
