USB 3.0 OTG cable

According to the specs, the G Pad supports USB 3.0. I assume that this can be used when connecting to a PC that supports USB 3.0. I'm wondering if OTG devices (e.g. external drives) can work at USB 3.0 speeds with the correct OTG cable. Does anybody know?

All it means I believe is that it's USB 3.0 compatible, which every USB 2.0 device is compatible. It does not have a USB 3.0 plug so it can't achieve the same transfer speeds of a USB 3.0 device such as the Note 2?
Since the tablet is physically incapable of accepting the cable USB 3.0 devices, you won't get USB 3.0 speeds from an external device connected via OTG.

I don't follow you. It's the other way around. USB 3.0 devices are compatible with USB 2.0 devices. It doesn't make sense to say that the G Pad is capable of USB 3 unless it can achieve USB 3 speeds. I just don't know in what situations it can use USB 3.

Just looked at LGs web site and the specs say the GPad is USB 2.0 only. It'll work with 3.0 devices just at 2.0 speeds. OTG works, tried with a USB thumb drive.

Yes and no, poor wording, I meant what you're saying :laugh:
But yeah physically impossible for it to support a 3.0 device in 3.0 form without the extra pins that USB 3.0 uses for transfer.

I don't know where I got the idea that the G Pad could support USB 3. Must have been an incorrect spec that I saw somewhere. Looks like you're correct that it doesn't support USB 3.

hi, have you already tried connecting a gamepad on the otg cable? does it work? or is there an app needed for it to work?

What is the Pixel C USB data transfer speed?

Hi,
I was hoping someone could answer this for me as I can't find an answer anywhere.
I was just wondering whether to buy the Google USB C cable that is stated to transfer at USB 2.0 speeds (480Mbps) or whether to buy a faster USB 3.0 (5Gbps) or 3.1 (10Gbps) cable (A to C).
I've found a few compliant USB C cables including a Belkin USB 3.1 A to C cable that transfers at 10Gbps and was hoping to take advantage of the USB 3.1 ports on my new Z170 based motherboard.
Thanks

I do not believe the port in the Pixel C is USB 3.0. Therefore, it wouldn't be necessary to get a USB 3.1 cable. It should still work, but you wouldn't exceed USB 2.0 speeds, which is probably why Google's cable is only USB 2.0.

Thanks for the response.
Is anyone able to do a quick transfer with a USB 3.0/3.1 based Type C cable to see if it maxes out at USB 2.0 speeds.
It would be much appreciated.

Most tech sites report the Pixel C has USB 3, but the fastest read speed I can get on a USB-C /3.0 flash drive is 27MB/s which leads me to believe even tech sites are confused and don't understand that USB-C does not automatically mean USB 3.

I think it was confirmed by Benson Leung, in the Reddit AMA, it's full host/client USB c spec so it's full speed port. Maybe another way to test would be to mount a USB 3 drive to pixel and storage benchmark it

I thought that the USB 3.1 host and client related only to the ability to charge the Pixel C as well as the ability to charge other devices from the Pixel C and to use the USB port for other devices such as an ethernet adapter.

That's pretty much what I did. A USB 3 USB-C MicroSD flash drive. On my PC it reads at 80MB+, on the Pixel it is 25MB

I'm a bit confused now.
Recently I read a review by Benson Leung on a USB 2.0 A to C cable here http://www.amazon.com/review/R1AF6ZHBZRQFHV/ref=cm_cr_dp_title?ie=UTF8&ASIN=B018HUOMYE&channel=detail-glance&nodeID=2335752011&store=wireless on Amazon and at the end of the review states:
In conclusion, this is a Good cable for your Nexus 6P/5X to use with all of your older USB Type-A chargers, hubs, and PCs. It also works great with Chromebook Pixel 2015 and will work great on USB Type-C spec compliant devices to come! However, it is NOT a SuperSpeed USB 3.1 5gbps cable. Look elsewhere if you are specifically looking for a 5gbps cable for use with MacBook or Pixel C.
Is this implying that the Pixel C is capable of USB 3.0 speeds, but perhaps not at the moment?
Or is it just a typo as a Superspeed USB 3.1 cable should be capable of 10Gbps and not 5Gbps (USB 3.0).

That is interesting. I'd suspect he'd know what the C is. I however, have never gotten more than USB 2 speeds out of it.

Micro USB accessories.-
For OTG accessories, and some attachments such as cameras, the phone is the USB host.
'Conforming' USB-C to micro adapters (listing the '56k resistor' ) will not work. Tells the phone to take a charge, it is not host.
Look for adapters that are non conforming, better yet are 'OTG' compatible.
One is:

Problem with old HTC M8 Charger
At home I use the charger that came with the phone.
At the office, I was planning to use the HTC charger that came with my old M8, maybe not quite as fast.
But strangely enough, when I do that, the charge light turns on and off every couple of seconds, it wakes the phone, and it doesn't charge.
A Belkin 2.1A charger I had works fine though. Go figure.

I don't think the HTC 10 is compliant with USB-C Power Delivery (Such as the Nexus 6p) do deliver the rapid charging speeds of up to 3A via a USB-C charger and a USB-C to USB-C cable. I remember reading up about it of an article referencing Benson Leung (not the 1st one, but most recent one). He said the LG G5 is compliant with the Power Delivery achieving the 3A max input. But the HTC 10 only achieves 2A.
I can about confirm this because I have 2 USB-C wall chargers, one by Cheotech that gives me around 1600mah-1700mAh, and one by iClever, which gives me the same speeds. My RavPower Turbo Series Powerbank with the USB-C port and the max of 3A output gives me the same 1600-1700mAh speeds of input into the HTC 10 as well.

I've tested a Samsung adaptive fast charger from the s7 and s6 with the OEM cable and a ravpower A to C cable and it shows Rapid Charging when plugged in.

Hi. I am confused and want to clarify, to quick charge my htc 10 or any other qc 3.0 supported device, do i need to have usb 3.0 cable alongwith qc 3.0 charger.
I am asking about qc 3.0, not 2.0
Will my device qc 3.0 with qc 3.0 charger and usb 2.0 cable? Or i need to have usb 3.0 cable to charge my device to qc 3.0
Thanks

Nothing is in common or related between QC 3 and USB 3 - apart from the numeral used... ??

Yes, in fact the cable that HTC provides is a USB 2.0 cable anyway.

Charging and transfer speeds with USB type C adpater question.

Are the transfer speeds or charging affected at all if you use the type C adapter with a micro USB cable?
Sent from my SM-G935F using Tapatalk

if it's a proper 10GBPS or 5 GBPS 3.1 type C cable, the snapdragon variants should be much faster for data transfers.
For charging, type-c fast charging is supported as well as QC 2.0, possibly 3.0.
Neither of these have been confirmed, this is from specs that have been posted to samsung's website and various other resources.
