Out of the blue my phone can no longer get recognized by any of the 3 PCs that I have, getting a message "USB Device Not Recognized".
The USB connection mode choice window on the phone does not pop up. The phone does go into charging mode, with LED and taskbar icon working.
Things I've tried:
1. Multiple USB cords (original Sony one, cheap Amazon one, bunch of others). Nexus 4 gets recognized instantly using all of these on all 3 PCs.
2. Multiple PCs and multiple USB ports on different hubs.
3. Restarted the phone and all PCs to no avail.
4. Factory reset the phone.
5. Tried manually setting the MTP mode in settings prior/after o connecting the phone.
Any other ideas?

This issue is in PC side
it means you should reinstall drivers on PC
first install PC Companion & if nothing changed try to install drivers manually

I'm having an issue where my thunderbolt is not recognized by my PC any longer. I used to have it set up with pdanet and everything worked well for about a week. All of a sudden, any computer i tried to plug the device into, wouldn't detect the phone. A friend of mine has tried his thunderbolt on my computer and it detects it.
When plugging my phone in, it pops up an error message with "USB Device not Recognized." In the device manager, the phone shows up as Unknown Device. I have tried this on 3 different pc's, using 3 different data cables. No USB symbol displays on the taskbar of the phone when I plug it in, however, it does charge.
What I have tried:
Changing data cables.
Using another PC.
Uninstalling device drivers and letting windows re-detect and install.
Downloaded HTC Sync and ran it after uninstalling drivers again and re-plugging the phone.
Changed different Connection settings on the phone, such as USB Debuggin on/off, and changing it to HTC Sync Mode, Charge Only, Disk Drive, etc
Mounted and unmounted SD Card in the phone settings.
OS: Windows 7 x64
Is there anyone out there that can help?
Thank you for any information you may provide.
I remember that one of my friend's desire cannot be detected by the pc before, he search the forum and find out that he need to change something in the driver files before installing the driver. I'm not sure if that will work in your case thought..
Hi,
I would like to see if I can get anyones assistance with solving my problem. I have lost the ability to connect my Nexus 5 to my computer via USB. I had previously been able to connect the phone without any problems.
Connecting my phone to PC charges the phone but no drivers are loaded, nothing changes in device manager and I cannot see a change in windows explorer to view the memory card.
So far I have tried the following:
searches on various sites
rebooting phone, starting in safe mode, wiping all data, performing a hard reset
connecting other phones to usb cable to check that it is not a charge only cable, also trying several other USB cables
connecting phone to other computers
connecting other phones (HTC) to load drivers (then uninstalling drivers)
displaying all hidden devices in device manager and removing all drivers that resemble something to do with mobile phones
uninstalling programs I no longer require on the PC
using "wugs nexus root toolkit" to uninstall and re-install drivers
checking & unchecking MTP, PTP, developer options, USB debugging in various combinations to elicit a response from the computer.
I have also tried to visually check the connections of the USB port on the phone wondering is there is a break but I cannot see very well.
does anyone have any further suggestions to get this phone connected to a PC?
my only last thought is to attempt to open the phone and check the resistance of the plug connections.
Have you tried enabling and disabling usb debugging while plugged in?

I just did it, no change in Device manager or explorer

Are you sure you're using a data usb cable and the usb port is good?
Same Issue
same thing happened to me today when i connected the device to PC.
Mine says unknown device on PC under other devices. so i hope my USB port is ok.but im not using the original SUB cable. i wonder that's is the issue. but it didn't bother me until today. my original cable is at my friend's house.
Tried updating drivers manually. But following error message occurs once i select the drivers folder and hit ok.
Windows was unable to install your unknown device
Please help.
so, not really a solution but while at work my phone fell on to a nice rock cracking the screen. I have replaced the phone and the new phone connects to the pc fine, drivers come up without a problem (I will put this down to a fault with the phone)
Thank you for your assistance
I just bought a used Verizon S7, and everything so far has worked perfectly with the exception that it is not recognized by my computer. When I plug in the USB, the phone only charges and does not even appear as a new device in Windows (10 x64). I have already tried installing and reinstalling the Samsung mobile device drivers, without success--same with Kief 3 and Smart Switch. I've tried every USB port on my laptop and PC (and my wife's MacBook).
I have already enable developer options, oem unlock, and usb debugging. I have also tried changing the USB configuration in the developer options menu (MTP, PTP, etc). What I find really strange is that "touch for other usb options" doesn't even appear under the notification bar. When plugged in, it simply says "charging."
I have tried factory resetting multiple times. I also tried upgrading the firmware to beta 7.0. Nothing has worked. Please help.

I have a note 5. With similar issues. Ended up being a bad usb circut board.
Would charge most of the time but no usb connections. In the end wouldnt charge either.
If u need to transfer files try a app called wifi file transfer. That and wireless charging was my best friend.
The notes usb circut board has the home and touch keys attached so it wasnt feasable to risk separating the screen and outer glass for a 6 dollar part. Not the s series may not be built the same.
That's interesting, though not very reassuring. Any ideas about the missing "touch for other usb options" under the notification bar? Since the phone is Verizon and already carrier unlocked, my plan was to flash to SM-G930U. But that is obviously not possible if I can't connect to Odin. Any other suggestions?

No my note 5 is stock unrooted no other way to do anything other than adb over wifi.
Hello there! I posted in the N00B thread without any success and so am casting a wider net:
I have a rooted phone that's been working well for about 1.5 yrs and all of a sudden it's not able to connect to the computer via USB. It was working fine til about 3 months ago, no new apps or changes to the system as far as I know. It still charges when connecting to the computer but I don't get the prompt to choose the USB mode and the computer doesn't recognize it as any sort of device. I've tried it on several computers that have recognized it in the past without luck (drivers up to date) and have tried different USB cords.
I've gone to USB and developer settings and changed and restored default settings for USB connection as well as toggled a bunch of other settings in that section.
I've wiped the Cache and Davlik Cache several times.
I cleaned out the physical port. Any other thoughts? thanks!
If you are on windows 10 PC, the latest windows updates could be an issue. I faced the same issue with my computer. After rolling back windows update (or may be resetting the PC to default settings) has helped resolve my issue and i could connect my phone again normally. It is nothing to do with your phone as far as i know.

You said the drivers were up to date but you didn't say whether you tried completely uninstalling the drivers. If you didn't, uninstall every driver you can find related to the Honor, reboot and plug the phone back in. I'm running the absolute latest version of Windows 10 and have no problem connecting my wife's Honor 8.

Thanks for your suggestion - I did try rolling back the update without benefit. Also, to reiterate - this is not being recognized by several computers (including a Mac) and that leads me to believe that it's the phone that's the source of the issue. I don't even get the USB menu (Charging, MTP transfer, debug mode, etc) when I plug it into several different computers.

Thanks for your reply- I uninstalled all the drivers and still nothing when I plug the phone in, after a reboot.

It may be too obvious but did you try another USB cable? If it's not the cable try this with the default dialer *#*#2846579#*#* then select in background>usb hisuite, connect the cable and see what happens.

I have tried different cables but no suggestion is too obvious! My sister in law actually also has an Honor 8 and her cable on my laptop is recognized, so that's what I've been using to troubleshoot with my phone. I did go into that menu you suggested and I tried toggling HiSuite, Manufacture, and Google and exit the menu and still nothing when I connect the cable (other than charging). Thanks

Have you played with any of the developer options like USB Debugging or USB configuration...... Nevermind, just re-read your original post. I was almost sure the dialer thing would fix it but if a reset won't I'm at a loss. I still don't think that it's a hardware problem but I guess it could be. There are things like wiping the cache partition that I see some folks have used for various problems. That would be an option that wouldn't affect your apps.
Phone is rooted and on android 10 and xxxnolimits installed
I connected phone to pc and only charging. Tried 3 different cables, including official one and 3 different USB ports and not showing on pc. I can hear noise it's connected to pc but then another noise to disconnect
Usb debugging is enabled and default usb configuration I can change to file transfer, usb tethering , midi, ptp & no data transfer. I changed it to each of them still not showing
There is no option to choose mtb from drop down notification no notification is there
I rebooted phone and pc and cleared cache. Also i app settings allowed notifications.
I'm at the end of my tether trying to figure out what issue is as was working previously.
Now all its doing is charging
Any suggestions

Do you have the latest fastboot-adb platform tools installed? Just a thought.
Will check
However usb notification drop down not coming up on phone to change settings when I plug phone into port.
Also plugged phone into USB port of car for android auto and not picking it up
If I restore a backup would that be worth trying or does issue seems to be with usb port on phone?

Try uninstalling and reinstalling usb google drivers on your pc ( or your appropriate driver's for your phone).
Install OEM USB drivers | Android Studio | Android Developers
Discover links to the web sites for several original equipment manufacturers (OEMs), where you can download the appropriate USB driver for your device.

Are you talking about usb drivers?
I installed this one
