Has anyone tried connecting a usb stick to the usb port of the phone with an adapter cable and then going into the bootloader? i noticed the message "failed to open usb master mode" flashes on the screen when first entering the bootloader. perhaps it's there because some newer phones don't have removable media anymore and this would be a way to flash files on it when you can't copy anything to the embedded mmc memory. maybe if the bootloader detects a usb stick it will mount it automatically.
I just tried, but nothing happened. Must be my OTA cable is bad. Also tried with USB keyboard connected to see if it makes any difference, but didn't notice anything unusual. Also tried booting HBOOT with some keys pressed but no luck But again, my cable might be bad.
wrong thread.

I was trying to put the hum/hiss sound fix on my sd card and I cannot get my pc to connect via USB...
My wife has a TP2 and it connects fine...
I have tried with/without the sd card in, rebooted the pc and phone, rebooted the phone while connected to the pc.... nothing...
wtf...
anyone else with this problem?
PS... NRGZ28 had posted a very basic rom for booting to android back in Feb and it is now gone from hotfile. Anyone know of a quick boot into android?
- Try a different computer
- Try a hard reset
That are the first thing you should do.
Tried hard reset...
Dif PC is not an option at the moment... I have rebooted...
Just flashed the ROM (NRGZ newest, thank goodness I had it on my SD card) and I still cant get it to sync...
I have attached the USB error I am getting... (Win7, new install)
The phone is not asking if I want to active sync or use as storage???? wtf...

Reboot your PC? lol bet your tried that already...
Try this:
settings > connections > usb to pc > and disable Faster Data Sync then try. This way uses the generic usb drivers and maybe it will connect.
That did not work...
How do I get my Win7 laptop to see the phone with Android on it?

dont think thats working yet
Ya I don't think that works yet, it's tied to Android software drivers and the use of the USB port, since there is no drivers to control the port only to charge battery. Windows thinks there is something there, but the phones USB can't communicate back....I think this is the issue or at lease after playing around with it on my phone anyway
Not that it's a huge amount of help but might troubleshoot down to the hardware level...if you go into bootloader mode on the phone and connect to USB does it connect?
I don't think you should go that deep and dirty. My touch pro 2 works only with only 1 (non-HTC) cable of the 10 i have at home, all are the "standard" mini-USB but only one works flawlessly for communicating/flashing/syncing, the other cables either do the same error - device not recognized - or windows says that the device could communicate faster - and only copies files slowly.
All in all: you should simply check with another USB cable or if you have the factory HTC cable try it with that. I noticed that the cable i am using other than the HTC one is a very good quality thick (low-resistance and double-shielded) USB cable and it never failed on me.
One other thing you should definitely watch for: plug the USB cable into the motherboard USB port directly (on the back of the PC where you plug the keyboard, mouse etc.), sometimes PC cases with front panel USB outputs simply die, or are wrongly attached to the motherboard USB header and it can cause the aforementioned problems too, not to mention if it is wrongly attached it could harm your phone too.
another problem occurred.
I flash the 11.1 nightly on my defy,(As flunk03 said, wipe cache and dalvik before and after flashing), it works very well, but an USB problem comes out, when I plug the usb cable to microUSB port, nothing happened, the phone do not show the usb connection, the computer do not "ding", either. Then I reboot the phone, it connects to the computer and shows me charging.
PS, after flash the ninghtly, I uninstall the MOTOROLA PORTAL, does it relate with the problem? who can help?
thx in advanced.
So it's not the cable or ports, try go to Device Manager from ur computer and see if you can see any unrecognized device? If you do, just download the Motorola usb drivers and install it ...

thank you, but my pc do not react anything, and it happens randomly, reboot, then it is ok. i do not know why? and when i plug usb cable to the charger, the phone shows it is charging, so i think it is the ROM problem or something.
I have a similar problem with the MS2Ginger 2.0 Lite:
After selecting USB Mass-Storage Mode in the top menu the phone says "preparing SD card.." and then shows "MTP: no SD card found" or sth - but there's clearly a SD card in the device and it's accessible, too -> i can browse through the gallery and everything..
No Mass Storage for me it seems...anybody got a solution to this?
Hey,
May I unroot HOX without USB? I actually have USB but something went wrong with pins so phone can just charge. After connecting to PC phone doesn't indicate anything, it just charges. Computers says that it found any USB device which couldn't be recognized. I have all drivers. Yesterday everything worked well. Tried another cable and computer. HTC Sync also doesn't see phone.
Now I'm using CM 10.2. Phone base is 3.14.401.31, CID__032.
When I had Desire I unrooted it just by flashing zip file via bootloader from SD card. Now I did't find similar option
Edit - I tried to put some ethanol to pins and now phone indicates USB, computer recognizes phone but just for 5 seconds. After that it again writes unknown USB device.
When I plug my handset to ANY computer (with, without kies or drivers, it doesn't matter) the phone charges, but, nothing appears on the computer (no unknown device or recognizing the two drives of the phone, but not mounting them (as it did before)) on the phone.
The "USB" icon doesn't prompt and if I go to settings/wireless and network/ USB utilities, when I touch the USB mass storage button, it prompts me to connect cable, which is already connected.
-USB debug isn't activated (I've tried both)
When my phone is powered off and I start to charge it, the charging screen doesn't prompts, It just start booting.
I've tried different USB Cables.
The Phone is Official Stock Never Rooted (I discovered this trying to root it today)
Am I SOL if I want to root it without a working USB Data port?
Any ideas?
i would say make sure there's no dust/ buildup in the port. I had connection issues once to find a pocket lint cramed in there. next do all the other stuff. uninstall/reinstall drivers, diff usb port, diff pc, reboot. My symptoms were similar to yours but i was able to reboot into recovery/bootloader and use adb/fastboot no prob, so not sure. and I was already rooted/twrp recovery. might be worth it to try fastboot in bootloader just to be sure and get a recovery on it asap. If that works you should be able to recover stock or flash whatever, then test usb again in diff pc with fresh kies install. good luck.
Sounds like bad/improper USB cables to me, not all USB cables support data and charging, make sure you're using an official Samsung USB cable.
If you have a friend with a Samsung smart phone ask to try their cable.
Hello,
My is not currently detected by my computer but it still charges. It was all working fine last week.
I don't even see in device manager as an unknown device.
I tried the usual things like another cable, another USB port, another computer and factory reset but none of this worked. I also tried to go in fastboot but when I plug the usb cable it says FASTBOOT AC and if I remove the cable it stays that way.
I also tried entering the #*0808# menu but it doesn't seem to work*(Connection problem or invalid MMI code)
Is there something else I can do? Is there any way to debug to see if it's the USB plug?
Thank you in advance.
