[Q] USB not recognized

Hi all,
My Droid charge decided to do something weird today; it no longer will USB mount! This problem is particularly bad because, while I can put the phone in download mode, my computer will not recognize the USB and ODIN (1.2 & 1.8) cannot wipe the phone.
Any suggestions? I really need my phone back, but I'm not sure what to do.
Tried reinstalling the USB Samsung Drivers, using the original data cable, and two different computers (Win7). SD card will mount in an external drive (aka without the phone), and the phone will charge via USB. I have the most recent form of CWM on it, and the EP4P debloated and rooted rom.
Thanks,
frak

That happened to me a while back. Mine had the added bonus of going into desk dock mode and staying there. It was a hardware issue with the USB port. It would charge, but nothing else. Mine did become intermittent though, and cycling the cable in and out seemed to help it some, but ultimately, I had to send it in for replacement

What cable are you using? I accidentally grabbed my charging-only cable the other day and didn't realized it only had the wires for positive and negative. No data pins.
Is it the cable that came with your Droid?

Another thread similar. Check it out and try some.

Had that yesterday. A different port worked fine for me. Maybe a couple of power cycles will do the trick.

Can you point me to the drivers you installed? Thanks in advance.
I am having same problem and going nuts. I have Galaxy S2. I CAN connect to windows and Kies when phone is booted up but can not connect while in download mode. On Andoid System Recovery <3e>, I tried to do factory reset and wipe cache but no vain. Still getting usb not recognized.

[Q] After update to 2.3.6, device won't connect to USB. Help!

Hi everyone! I've updated my Samsung Galaxy i9003L to 2.3.6 via Kies a few days ago, and USB connection has stopped working for seemingly no reason. The phone just charges but never mounts. Kies doesn't detect it either.
On Win7, when I try to connect I get the device listed as "Unknown Device", error 43. Have tried uninstalling USB drivers and reinstalling official Samsung drivers at least 5 times. Didn't work. Also, Kies doesn't detect the phone. Have tried running Kies' connection troubleshoot tool. Didn't work either.
I've tried connecting the device with 3 different USB cables (including the original Samsung one), and on different USB ports as well. Didn't work either. Also tried putting the device on USB Debugging mode, to no avail. I've also cleaned the USB port in the phone just in case. Problem persists.
My Linux netbook used to detect the device with no problem at all before the update. Now it doesn't detect it either. I've also tried my GF's Mac, but no dice. This makes me think this may be a phone error.
I've also tried the *#7284# USB/MODEM solution and rebooted my phone to factory settings twice already. Nothing seems to work.
I'd appreciate some help on the matter, this is driving me slightly crazy!

Hi! First of all, thanks for the help. I doubt this is a firmware problem, since neither mi Linux netbook nor a Mac computer detected the phone in any way, and they also used ot be able to detect it with no problem.

[Q] Phone won't connect to Odin

I had to install the 4.3 firmware on my S3 since it got soft-bricked, but it seems that even though I installed the Samsung USB Drivers and installed Odin, my phone won't connect to Odin. I tried using different charging wires and different USB ports, and that doesn't work either. Even my friend's phone, which was an S3 as well, managed to connect to Odin with the same charging wires. Is it something to do with my phone? I need help with this.

My S3 updated to 4.3 (locked bootloader) and I can't make it connect via USB, it won't connect. I've tried everything, every link I can find, reghacks, drivers (countless installs/etc). I know what I'm doing, I've been using computers longer than a lot of posters here have been alive.
The thing is the device isn't telling the PC what type of Hardware it is, let alone the PC having drivers. I actually think my phone is toast - I'm glad it still charges and you can (if you're not rooted) root via Towelroot without a PC.
Good luck.

Galaxy S6 not recognized on PC or ADB

Dear,
My Galaxy S6 SM-G920F with lollipop 5.1.1

I can't figure out eitheir its hard or soft.

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.

Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem

i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.

Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you

I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

Weirdest Problem i had on a Phone ever.

Hello,
I'm having a problem with my Unlocked Galaxy S6 (SM-G920F) When i plug the USB to transfer data from my PC, it only detects it as charging, and yes, i know i should change to MTP in the notification center, but i don't get that option, I've enabled it manually in the developers option, also enabled USB Debugging Nothing. Then I've rebooted to TWRP , still nothing. Tried connecting via ADB Doesn't detect it.(I'm sure that cable works , tried it with my Galaxy S5 mini , it works), So i went to Download Mode, Fastboot commands doesn't work , but weirdly it detects in Odin. Good, not great. I've decided to revert back to stock, flsahed the latest firmware. booted still nothing just says Cable Charging as if it is connected to a wall plug.
I don't know what do now .
Any help?

My S6 does a continues connected/disconnected loop on my laptop but on a desktop PC it runs great. Other phones also run great on the laptop so it's possible that you too have an isolated case.
A dumb suggestion, did you try clearing the cache? Try downloading Samsung Smart Switch on your PC and run the built in device driver reinstall function.

I personally think that it's a computer problem rather than a phone problem. If you flashed stock ROM only and didn't touch anything special it MUST work because we would have seen people complaining by now. I'm still holding onto the idea to check the phone with another PC. IDK, maybe you somehow blocked the phone on the laptop? (Download mode and "OS mode" are different things so that would clarify why the laptop detects the phone in ODIN mode)
