My lg g5 ls992 is not recognized by a computer when i plug it in. If I do something to make windows refresh the driver it shows usb device not recognized for a short time. Windows makes the connected sound and within 30 seconds makes the disconnected sound while it is still plugged in. My wife has the same phone and her works fine. I have tried everything, reinstall drivers, usb debugging, usb mode, factory reset. I even tried swapping the bottom module. Nothing is working.
Hi there, did you manage to get anywhere at last?
Cheers.

Today i plugged my phone to the usb cable and instead of getting the usual connection option screen... nothing... The phone charges but no Data transfer. Did hard reset, still nothing.. now im stuck with the old firmware... any help plz?
might be the cable that you're using. i used before a cable that is not the original and the same thing happened to me, i.e. pc cannot recognize device.
Try Settings-->Other-->USB To Pc-->UNCHECK (enable faster data sync) this should help...
cable : original came with the phone (used to work up until b4 yesterday) also tried another micro usb cable that came with me N900 but still nothing.
I did the un-check "enable faster sync" still nothing
Did soft reset, hard reset using volume keys, and factory reset from phone setting itself. still nothing.. the phone charges.. but no data transfer.. its something to do with the phone because i tried multiple PC's the phone doesn't bring up the connection type option page

No harm in checking.Infact i faced similar issue once and the USB2 was disabled.It took me an entire week to diagnose the problem.These PCs have got a mind of their own and do mischievous things on their own without our knowledge.
But since its not working on multiple PCs,i am not sure.We'll hav 2 wait 4 a solution i guess...
hmmmm.. would a full system format and re-install be possible? and would it fix it? (talking bout on the phone)
HELP, HELP
SAME PROBLEM WITH HTC2 T0MOBILE

PLEASE HELP
i can do nothing, HSPL or rom upgrade
the cable and the USB drivers are tested more than 100 times
Most horror problems I had with the USB sync have been down to not having the latest version fo Activesync from microsoft. Uninstall the old version thwen reboot - now download the 4.5 version which I think is the newest and last version they made (unless im out of date) and then reboot the machine, then connect up the phone - but not immediately after the machine has booted wait a couple on mins, Windows takes longer than it often appears to be ready to go. One your hard drive led flashing light has settled down it is probably time to try. Then see if it finds all the devices in your phone.
If it doesnt go into the control panel and double click system, hardware tab, then select device manager and see if there are any devices with a yellow sign with a "!" in them. If there are delete them and then unplug the phone and plug it back in again. It might get past some stuck things. If it doesnt see anything new on device manager theres a menu at the top and look for "scan for hardware changes" this gives teh device manager another look at what its got connected.
If that fails open up the USB section under in device manager - its got a little plus next to it, press that plus and it open up all the names of chips you have for your USB control on the pc's motherboard. Write down the numbers and go and get the correct up to date drivers for that type of USB and install them. Then try the process again. Sometimes deleting the USB drivers and just doing a "scan for hardware changes" again, will reset the USB drivers and start things working, however it can get tricky if your using USB mouse and Keyboard to select anything if you delete the USB, because thats what the KM/mouse relies on to control teh machine, so have a PS2 mouse plugged in if you can. If that fails I would suggest reinstalling windows as its probably knackered. It amazing how things start to work wonderfully on a fresh copy of windows.
I have been where you are! And tried every suggestion that was given here. It all came down to the cord. I actually went through 3 different cords before I found one that worked and found that by accident. I bought an external drive and that cord works. For whatever reason, that is the only cord that now works for me. I only use it for data transfers. i use the other cords for charging.
Sorry but, believe me, I've been dealing with this all week and I have read every post possibly pertaining to this subject, but I can't find a fix.
Went to flash the latest Bionix and PC (Windows XP-32/64-Bit HP) won't recognize my Vibrant. It's the only machine I've ever used with this phone. I plug in and get the USB icon and the Android Debug icon in the menu bar. Pull it down and it says "USB Debugging Connected" & "USB Connected". I can "Connect USB Storage" if I like, and it says "connected", but it's never recognized by the PC no matter what.
I can go into "Media Player" mode and "KIES" and same thing, it's just the USB icon instead of the Green Android. I've changed cords. I've used all the ports, front & back. Flashed back to Nero-5. I've gone into download mode and ODIN doesn't pick it up either.
32-Bit drivers are updated, but I've been doing a lot of install/reinstalls. The last thing I did on this device was flash Bionix-V. A couple weeks later I updated my wife's stock Vibrant via KIES.
What the hell can I do now? Thanks
edit...nevermind, sorry...at least i bumped you!!
Ha! Thanks TS10. And Mounting was certainly part of the problem. I could connect the USB storage and, in fact, it would say “connect” on the phone (“You can now transfer files between your SD card and PC” or something close to that), but it would still not show up on the PC. That’s what was driving me CRAZY.
But get this… Late last night, out of total frustration, I plugged the cable into a USB hub, that was connected to a removable HDD, and suddenly the Vibrant was recognized. I couldn’t believe it. I had plugged directly into that same USB port, on the back of the machine, at least 6x. Why the hell would it connect through a USB hub?!
I have no friggin’ explanation. But I’m running the latest Bionix now! At least I though that until I just check in here.
I have a really weird problem. My computer won't recognize my SGS2 is connected to the computer at all. Meaning no notification sound, no device change in device manager, nor any prompt to install a new driver. I've tried in both MTP and Mass Storage. What's even weirder is that it detects the phone in Odin mode and even installs the correct drivers. I've tried just about everything I could think of, such as the following:
-Cleaning the microUSB port with alcohol & new tooth brush
-lifting the microUSB connector slightly
-Using a toothpick to try to pick out any residue in mUSB port.
-Connecting while TWLaucher is set as default
-Using Wireless & Network setting > USB utilities.
-Taking out the sim card and external microSD card and booting & rebooting it.
-Restoring the stock Firmware
-Different wires, including an untouched mUSB wire that came with the phone.
-Different computer that doesn't have Kies or the said drivers installed. (Still didn't make a notification sound or bring up the "new device" prompt)
I just want to make sure I tried everything possible before sending it in for repairs.
EDIT: Oh forgot to mention that I had other problems before getting to this one. About a week ago Car mode would always activate by itself constantly. Even during use. Also the phone would refuse to stay turned off. After booting down, the phone would turn off. However, after some random amount of time, the phone would turn on by itself. During that time, connecting the USB wouldn't keep charging the phone. The phone would go between connected and disconnected randomly. Sometime off and on multiple times with in seconds. Other times would charge for hours and randomly stop charging. I've gotten the phone to charge whenever its connected now by cleaning the port, but the computer still can't recognize it as a device. Also the screen will randomly turn on, plugged in or not, and I have to manually turn it off again. However, if I turn it off right away it seems to lock up. So I have to unlock the phone the press the power button again to lock and turn off the screen. Don't know if this information helps.

Try another usb port, sometimes that helps or reinstall the usb drivers in Kies
Ignore, hadn't read all he'd tried.
Bump: Additional information.
Same problem here
I have exactly the same problem!!
My thought is that the USB connector get wet and stopped working properly. As fas as i know, USB connector is composed by 3 cables, one for charging, one for data transfer and another one to detect Car Dock.
It seems that Odin is using Car Dock cable (?¿?¿) instead of Data, so you can use Odin and not Data.
Also that would explain why car mode just kicks in by itself (short circuit between car cable and probably power cable).
I will also sent it to a SAT, since i tried everything via software....
I have the same problem. Try plugging into a mates laptop, see if it works on their one.

Really don't understand this!
Mine is showing up sometimes.. :s little hit and miss
Sent from my GT-I9100 using xda premium
Running 5.1.1, I've tried installing the latest drivers from verizon & LG along with Windows10-KB3010081-x64.msu on two Windows 10 machines, and just the drivers on one Windows 7 machine.
When connecting the phone it displays it's charging. If I tape where it says "Battery full, safe to unplug charger" it closes the app drawer.
I've switched between MTP and PTP in storage settings-nothing happens.
I've turned on USB debug in developer options, still no go-the device does not show up in device manager at all.
I've tried the micro USB cable that came with my phone, along with a high speed insignia cable, and two cables that came with kindle fire tablets of various generations.
I've tried using the LG Suite-nothing happens, doesn't discover the device which I was expecting since it doesn't appear in device manager at all.
I've also factory reset the phone, it's never been rooted or had a ROM flashed, completely stock.
Anyone have any idea what I can do from here?
So, I have received a hand-me-down Nexus 9, and I start in on my usual cleanup and setup routine, only to find something very weird- my computer utterly does not notice its existence when I plug in the USB, and the USB settings are missing from their usual spot in the Storage and USB section of settings.
I eventually found the control for USB type in the Developer settings (maybe it moves when you activate those?), but the computer still doesn't know anything's connected.
Things I have confirmed:
Tablet charges fine.
The cord works for file transfer with another device (a Kindle that happened to be around)
I can change to different USB connection types- none of them work.
The computer is COMPLETELY unaware of the tablet- no mysterious entries popping up to indicate missing drivers, nothing.
WTF? I can't do most of the other steps I usually do without at least a little bit of access so I can root the thing and put in a decent recovery. Has anyone else seen something like this? Was there a fix?

Try a different cable.
Boot into bootloader and see if computer sees device there
When you plug your tablet to computer a notification pops up on Nexus 9 (Charging only). Click on it and you will be able to select different connection mode.
If changing that notification mentioned in Post #3 doesn't work, updated the USB drivers in the computer Device Manager while the Nexus 9 is connected.
I had a similar issue with a Nexus 9 I bought on Swappa. I had to wiggle the usb cable, but in my situation the "data" portion of the usb port on the tablet was faulty/damaged (PTP/MTG/OTG failed). It was able to charge without issues, and by wiggling it windows would detect it but fail "usb device malfunctioned".. I ended up returning it to seller.
I've had this happen at times (only owner of my device). If you did what maelfilk suggested and no go, you either have a power-only cable (similar to what clockcycle posted) or you need to go through process of upgrading driver on PC; or, if that doesn't work, delete everything related to android USB drivers on PC. Then, let them (each device) repopulate.
