After upgrading to ATT WM6, I am receiving a USB device not recognized more often than not when I try to sync via Activesync. I tried resetting, restarting the phone and/or computer. Advanced network option on phone USB to PC connection is off. Any ideas? Thanks.
WM6 & Firewall
When I upgraded - my firewall was not happy anymore. Try killing your firewall, deleting any previous settings in your sync center for the device, than reconnect it.
Still problems with USB, Activesync 4.5 and WIN XP
I reinstalled usb drivers, activesync, and reset the phone but no dice getting the computer to recognize the phone. It will briefly but activesync never gets rolling before it drops.
Im currently having an issue where I plug my phone into USB on its cradle, and it connects ok, but after about 30-60 seconds it disconnects and reconnects. Very annoying.
However, BEFORE I got to THIS point, when I plugged my phone into USB from a hard reset (actually a replacement phone) it would just say a USB device has malfunctioned and has not been recognised, or something like that. I finally got round it by disabling the advanced usb networking functionality as you said you tried - but I noted that it only actually worked after a hard reBOOT. i.e. after switching OFF advanced networking, the effect of doing so didn't become apparent until I had rebooted the phone - at this point it recognised it, installed the drivers and Vista Windows Update went and upgraded all the drivers.
Now I just cant get it to stay connected for more than 30 seconds or so :/
Hard reset did the trick.
Thanks for that pearl.
Hi All,
Can anyone help me in getting the issue resolved that I am facing.
Few days back all of a sudden my PC stopped detecting my Phone (Samsung Vibrant). I thought it might be an issue with my PC so I tried to connect the phone storage on some other PC, but the result are still the same.
I am also not getting any pop up notification on my phone to "Mount".
I can download anything to my phone via direct internet browsing but cannot transfer or upgrade my phone via my PC.
I checked all the setting and also restored my phone to Factory Default but still the issue persist.
Pleeeeeease guys can someone pleeeeease help!!!!!!!
Sorry to say this, but seems like a hardware problem. Did you tried with a different cable? Try Different port on the PC? What happens if you plug the phone to a wall charger?
Is the phone still on warranty? You can send it back to Tmo and get a "new" one.
Try a new cable.

Yes I tried different cable and also tried different port of PC but nothing happens. Also the other functions works as normal.
The phone charges when I connect to my wallcharger or PC. I often get a messag from my PC that the harware is detected but is not properly installed.
Any clues, also I cannot send it to TMO because I am not in states right now and TMO does not works here.
will flashing the ROM work?????
This has happened to me before. What usually works is to reboot the computer and then connect your phone to it. Wait for the connection error message. Then go into ur device manager and find the "unknown" USB device. Make sure u both uninstall and delete the "unknown" device. Unplug the phone. Reboot the computer again. And once its finished booting up plug connect your phone again.
Always works for me.

Verizon Note 4, non rooted running stock 5.0.1
Ever since I got my phone (used) I've been having issues with WiFi. At first it started after I use HotSpot couple of times, after I turn it off WiFi seems to be on but either doesn't see any networks, or connects to my router(s) and get's no Internet. Reboot always solves it.
At the same time I usually start having Bluetooth issues (won't connect). Again reboot helps.
Then it started to happen every 2-3 days even when I'm not using HotSpot feature.
Once every blue moon, phone will get stuck in Wireless Charging mode (I have Samsung inductive cover and charger). It will say "now charging wirelessly" when when my phone is miles away from charging base
Again reboot was only remedy.
I did a factory restore and it didn't help a bit.
Lately I started to have USB issues. When I connect Note 4 to my computer via USB cable, it's not detected and phone is not even charging! I thought it was my USB hub (which btw has high current 2.1 A ports) or ports, but after I rebooted phone USB started to work.
Any clues what might be happening? Could it be hardware issue
Hello
I have an issue with my OP2, I tried with two cables and two pc but it fix nothing
I use the tethering with an usb cable on my pc and sometimes the connection breaks off, of the blow I try to deactivate and reactivate the tethering connection except that the pc does not detect any more the phone.
That is the phone charges but I cannot enabling mtp etc.
And when I restart the phone, everything takes back. But the issue come back randomly
Anyone have an idea of this issue ?
(Sorry for my bad english)

Maybe try a clean flash/factory reset and reinstall your oneplus 2 drivers on your pc

If you can confirm that the issue is not because of the cables, then it is most likely about the usb driver on the PC.
Try connecting another device with these PCs to see if the connection problem persists.
If not, then just reflash the device or try factory reset.
Otherwise, it is the problem with the PC side. Download the driver from a reliable source and reinstall.
Hello, in fact it was the cable and the firmware, now i'm on 3.5.6 and there is no issue anymore, thanks for your answer and sorry for the late
Hello, I've had the V20 for a number of months now and love the phone, but I never tested out a data connection before, only to find out that when I use both the LG cable and a Anker USB3.0 cable, my phone is not able to connect to any computer. The system prompt to select the MTP or PTP connection appears, but after making a selection and the computer seeing the phone for a split second, the connection is lost and the USB prompt appears rapidly over and over again. I even went into developer options and set MTP connection always.
I tried a reboot, battery pull and capacitor discharge, and a full system restore. No fix. The only work around I have now is a samba server or moving files with the SD card manually.
Please, if you have any ideas? Does not work in Windows and Linux.
Thank you.
Have you installed LG bridge?

Did you enable USB debugging in Developer options? If no, enable it.
Change the power settings in windows for the USB.
Power options
Advanced settings
Disable "USB selective suspend setting"
Tried all the above

Yes, USB debugging works and I'm able to use ADB with my phone and both the Windows laptop and Linux Desktop. However, neither is able to reliably connect through the typical MTP and PTP methods. I finally got MTP to limitedly work with MTP when I use the LG supplied cable and ignore the USB connection prompt in Windows and Linux. I go straight to File Explorer and access the file directory of the phone. Every time I open a folder or access a file though, the phone rapidly pops up the USB connection message over and over while the file moves.
All third party cables and USB devices are not working other than just charging. In Linux, the error message in my logs is:
usbfs: process 20678 (mtp.so) did not claim interface 0 before use
reset high-speed USB device number 101 using xhci_hcd

Is this behaviour on accessing and copying? You can not copy a file from your Windows laptop to the phone?
Yes, I cannot open folder directories, nor move files from phone to computer or visa versa.
Also. Try to not let the phone screen turn off. Change display time to 15 minutes or something.. Change back when finished. GL

No change.
dbo989, did you resolve this issue? By any chance are you running avast mobile security? I was able to transfer files both ways via USB and had the pull down USB options without ever having to add USB debugging. Then I installed AVAST and USB has become charge only... none of the widely recommended solutions above will unlock USB. I see no apparent settings in AVAST so I will call them. If no resolution then I will trash Avast

No, I never could resolve it. I ended up using Samba to fileshare with home computer, but lost any OTG cable ability. Never used antivirus or security software with my phone.

Just fixed it... turned out to be the port on my PC, I switched ports and its back as it was, no need to enable dev mode or USB debug... its still slow connection... I have to look up Samba solution, never used it.
Thanks for sharing
I just experienced the same problem with the USB connection constantly cycling between being plugged in and not. Windows kept alternating between the device connected and disconnected system sounds. I unplugged the USB 3.0 to USB-C cable on both ends, unkinked and straightened it, and plugged the cable back into the PC and the phone. Hasn't made another peep for the last half hour and the phone is staying in USB file transfer mode. I wiggled the cable at the phone end and still no further disconnections. Maybe I didn't connect the cable securely at the PC end the first time.
This is the first time this has happened since I started setting up the phone this week, so I don't know what to make of it. Regardless, I need to order some more USB-A to USB-C cables since this is my only one.
USB File Transfer Issue - Resolved
Hi, I had the exact same issue with the computer not seeing the phone as far as files. I was still able to use ADB, Fastboot, etc, so I figure it was not a hardware problem. Tried two different computers as well. Every time I selected "File Transfer" in the USB settings, the phone would beep, and when connected to the computer, the computer made the usual chime. The phone would not show up in explorer still.
Previously this phone had been rooted, but I wanted to bring it back to stock. I had flashed the latest KDZ file. Then using ADB and Fastboot locked the bootloader. It seems that the USB issue happened after that. Here is what finally fixed it:
Turned on developer options the usual way (tapping build number in software info) and then turned off "Allow OEM Unlock." Then I turned off developer options. Still, no luck, so I then re-flashed the latest KDZ (H91820h) again, but this time with the bootloader locked.
After everything was done, I set the phone up again, and now file transfer works perfectly.
I did not want to chance locking the bootloader while the phone was still rooted. I learned the hard way about that, and nearly bricked the phone once before. Luckily I still had factory upload saved in the LAF partition.
Hope this helps someone out there.
Turns out it was not fixed permanently

After thinking it was in fact fixed, I rebooted the phone several times, turned off, then on, and all seemed well. Until the next morning. I turned it on, and the same issue happened again. No File Transfer mode to computer. ADB still worked. After being on for a while and getting warm, all of a sudden file transfer started working again. Rebooted, and turned on and off, and it continued to work. I figure its a bad part with a thermal issue somewhere so I put it in the freezer for 5 minutes. When booted up again, the same problem occurred until the phone warmed up. Weird? So I tried something completely different. I downgraded the phone to H91810p and tested again. It seemed to work fine. I put it in the freezer again, and the problem will not show itself. For whatever strange reason the problem appears to be heat related, and ONLY happens with the latest KDZ, Oreo 8.0 The only thing that I can theorize is that the SOC is bad, or there is a bad area of flash memory that is intermittent.
Does anyone have any clues? I am going to put it back in the freezer, go to work, and test again when I get home to confirm.
