I have just found this:
Code:
# set default usb mode as usb mass storage
ro.default_usb_mode=2
It goes in build.prop. Valid values are 0-4. As it's "ro" (read only), probably you will have to reboot after changing the value in build.prop to test. If you do, please report the results. Thanks.

have you pulled the notification bar down and pressed the icon in your notification bar, a green adroid dude. Then press the "turn on USB storge" button underneath the green adroid guy. Then there will be another prompt to let you know that your SD card will not be availble to you phone while in this mode. This will put in the storage mode(SD card to Computer)

Nothing pops up only the charging light

Try a different cable

I have tried about ten different ones

Besides what user arkoze said,
Have you tried to disable/enable USB debugging mode in settings?

Kindle not showing up as Mass Storage after Using AOSP Rom

I recently updated my kindle with the AOSP 4.2.2 rom found here: http://forum.xda-developers.com/showthread.php?t=2041694
it works perfectly and smooth, but the device no longer shows up as mass storage when plugged into my pc. I looked through all the settings and enabled the developers menu, but I still do not see an option to turn on mass storage. USB debugging is activated when its plugged in but there is no option to turn storage on. Does anyone else have the same rom/problem. I am unable to post in the developers section so Im hoping I can get more info here. I would hate to have to install a different rom.

Hmm......I know from personal experience (happened yesterday) that the USB cord might be at fault but that's one of many possibilities. I experienced the same problem, switched cords and it connected after I used a different cord.
Have you tried to connect in TWRP?
BTW.....what operating system is your PC running?

I did not try a different cable. I put my old rom (AOKP 4.1) back on and USB storage worked again, but disappeared once I put the 4.2.2 rom back. It always worked flawlessly with the old rom. The computer I tried this on is running Linux Mint 14.

If you looked for this feature in Developer options, then I would say 99% you were looking at the wrong place.
Get into Storage -> Menu and turn on the UMS from there.

Sorry to sound lazy but if it's not too much trouble, why not just stay with a ROM that connects?

I looked in all the standard menus before enabling the developers options. Seeing now, that Im not the only one, Im assuming it might not be enabled in the rom.
I just had to flash my kindle back to stock so I can exchange it, but ill take another look at it when I get my new one.

You have to enable USB debugging. It will show up under Portable Devices in Win7.

This didn't work when I tried it, but I did find the answer. Under setting> Storage, I had to pull up the additional menu in the top right corner and enable mass storage. In previous ROM's I used it was in plain sight under the storage menu. Thanks for the reply.

[Q] MTP, PTP, HiSuite, MassStorage

Hi to all,
everytime I connect my Ascend P6 (b125, no ROOT, no MODS) to PC, it connect as USB MassStorage. (then I can not see in menu applications, that are installed or moved on SDCard). I can change connection type, when I pull down status bar. But I want always connect as MTP. Is there a way to set default connection type to MTP? Before I had Samsung with cyanogenmod, and there it was in Settings -> Networks and connections -> USB (or so something, dont remember...)
thanks.

I had the same issue, but not always, when my phone was connected to my pc

When you connect your phone and change the connection from USB storage to MTP, there should be an option right at the bottom, that says "Always prompt something-something", and untick that.

I have it unticked while selected MTP, but when I connect phone again, it connect again as USB srorage

Maybe the ROM/Kernel don't support Mass Storage.

My phone also started having this issue after it decided to restore itself to factory settings on New Year's Eve. It's really annoying! Would love to have someone provide the solution here.

Bumping this thread. This is causing a huge inconvenience for me. I'm discouraged from charging my phone over USB now.

Which firmware are you on? What have you installed? Did you install any custom roms before, and which ones? Which recovery do you have? TWRP or stock?

B125 stock rom with standard apps. The issue began in B118.

Just updated to B137 and the problem persists. Completely giving up on this phone as I have a Nexus 5 inbound.

Hello,
I published a post here related to this pb.
This does require to modify boot.img which is a tricky operation.

I have a similar problem. When i plug in my Huawei Ascend p6, nothing happens it just starts charging. It use to open a window where it asked me what type of connection i would like to use, i probably selected charge only for default, and now i dont know how to change it back. Pls help.

[Q] galaxy nexus troubleshooting help please

hi, i got this sgn from a friend with a broken screen, and ive now replaced the screen and the phone turns on and boots up no problem. but when i plug it in to my puter, it says usb device not recognized, one ot the usb devices attached.... as well in settings the wifi on/off toggle starts greyed out, if i go into the wifi setup, i can push the toggle and it says turning on wifi, but then after about 20 seconds or so, it just flicks the toggle back to off. bluetooth if i press the toggle, it instantly flicks back to off, and wont turn/stay on. and the last thing i have noticed that is not right, is when i try to go into the camera, it just f/c's and says gallery has has stopped, yet if i go into the gallery, it comes up. but f/c's if i try to access the camera.. i am thinking its probably a hardware issue, just was wondering if anyone might be able to give me any extra insight or suggestions, thanks in advance.
edit: oh, and the phone charges through the usb port, which i find weird that the puter wont recognize it...

yeah, ive got a usb jig to boot it into odin download mode, but i think i tried it but the computer still didnt recognize it, ill try it again and let you nkow what happens.. also, i have another working sgn here, and i switched out the boards, cause the usb port is not on the mainboard, it is connected by a flex ribbon (thinking it may be a faulty usb port) but either one generates the same results..

You dont need Odin. Just use fastboot and flash the latest Factory image. There are plenty of guides on how to do that. Good luck! If you cant get it to work just let me know.

okay i tried your advice, but the computer still fails to recognize the phone, i installed the drivers, cause the computer picks up the other sgn that i have here, i just unplugged the one thats fine, and plugged in the one i am trying to fix ant it doesnt do anything,...

Go to System Settings -> Storage -> 3 dots -> USB connection, and set MTP ON (V)
and if that doesn't work, try another DATA cable

tried setting mtp on, tried setting ptp on, tried setting debugging mode off and on, tried a different cable, still nothing..
something i did notice was that i have another sgn here and i went to the storage settings, and i was able to uncheck both mtp and ptp and my computer installed a new device "samsung something something" cant remember what the new device was tho..
oh and the bootloader is locked on the sgn im trying to fix and it is unlocked on the second sgn i have here...
could that have something to do with any of this?

Have you enabled USB debugging in developer options? (to see developer options, click on "build" under settings several times until it appears.)

yes, tried that. tried different USB cables, installing/reinstalling usb drivers. I copy shows and things to my tablet to watch and It used to work, but it hasnt in some time and it kinda sucks having to power off tablet and pull sd card out to copy to it. Just getting frustrated with it. I even reset the device and updated it to android 5

Running through options, sounds like the computer. Can you hook up your phone?

Yea, phone shows up ok and just for the hell of it plugged tablet into laptop and it came up fine so i guess i have to figure out what is wrong with my desktop
