When I plug my AT&T LG Optimus G into my computer, an "LGE Mobile" window pops up, and I have the option to AutoRun. Whether I click it or not, within a few seconds, the drive is unmounted and "Device driver software was not successfully installed" pops up in the taskbar. I've installed the LGUnitedMobileDriver a few times to no avail.
This is happening on both my work iMac running Windows 7 in Boot Camp and at home on my PC with Windows 7. I've gotten it to work before, but I am unable to replicate whatever I did before. I did something like plug it in, change it to Charge Only on the phone, unplug it, plug it back in, set to Media sync, and then it worked. But that's not working now.
Any ideas?

Are you getting "usb device not recognized" from your computer?
You've installed the samsung drivers?
Was it working at a given point in time and now it doesn't work all of a sudden?
I had a similar issue this week where i got "usb device not recognized" from my computer everytime i plugged in the device. I thought i had not installed the samsung mobile drivers properly, or my usb drivers on my PC was messed up, etc etc.
It turned out that my USB charging cable was the issue. It charged my phone fine but did not let me connect it to Odin or even transfer files.
So my suggestion is to try to find someone else's cable and give it a shot.
I used an AT&T captivate cable from a coworker and that's how i found out it was my cable.

from desktop, windows button, in search box just above button type device manager, should be at the top of the windows pop up, clock that, go down to usb controllers, click the plus sign box. the rest was explained above.
USB fix
So I had the same problem. A new oem cable solved it. don't fight too long with this problem just get a new cable.
Today I deleted some programs off my SGS2 that were in the list in the SGS2 General Forum. My phone was able to connect to the PC before that. After I uninstalled the applications on my phone, it no longer tries to talk to my computer. I have reinstalled the drivers, restarted both my computer and phone, and still nothing. I am worried it was something I uninstalled but I doubt it. I was quite careful removing the programs using Titanium Backup and they were completely unrelated in my opinion. I have a feeling it is only coincidental.
Anyhow can you please help me troubleshoot what has happened? Thanks.
Perhaps it wasn't related. I figured out how to do it with USB debugging ticked. I never had to do that before. Originally it would connect automatically with USB debugging unticked. Now it only connects with USB debugging ticked and after I say that it is 'OK' pretty much.
Still, if anyone can shed some light on what I may have uninstalled let me know. Thanks.
may not apply to you since im guessing you tried it both times on the same comp with the same OS. i find that kies hates 64 bit OS. it just wouldn't connect on my desktop running win 7 ultimate 64bit but connects just fine on my laptop running win 7 enterprise 32bit. anyway... i usually have debugging mode on anyway, much easier for me to access the phone and sd card using explorer instead of stupid kies. kies i only use for firmware updates or atleast until i've rooted this thing.
Sorry I should have mentioned that I am using Windows 7 Professional 64-bit. Thanks, shabs52. Good to know it could be my OS that is fumbling. I would have to agree as well, Kies stinks. I can't wait until I can get a stock OS without any crapware.
Anyhow it is strange how it worked for awhile and just stopped, but debug mode is better anyway.
Win 7 x64 Kies failed always .
Wiped drive brand new Win 7 x64 install Kies no problems = bad driver install or conflicts on original setup .

I'm having this problem too
Despite my Win7 64bits, Kies always connected automatically, both with SGS2 and my previous SGS. Yesterday my SGS2 started to behave strange: when I plug the USB cable it doesn't recognizes automatically (takes a few seconds), and only starts charging the battery, but the data link is not stablished (Kies won't even recognize there is a device connected). When I remove the USB cable the charging indicator continues to show as if it still was connected (again, for a few seconds). The same with the power cord. Since the symptoms were the same in my notebook (also Win 7 64) I tried it on a Win XP 32 - same thing (different USB cables). This makes me think the problem is with the device itself. Anyone have seen this?
Try deleting the drivers on your pc for samsung usb while the phone is unplugged. Then plug back the phone and windows 7 should automatically search and install the required files...worked for me with w7 64
I already did that, but the problem persists. Today some new symptoms "arrived", which led me to this other thread (http://forum.xda-developers.com/showthread.php?t=1151863). The phone eventually enters car mode, or beeps and shows the charging indicator (even though it's not plugged). Weird. Will take to service tomorrow.
Im having this same problem with my epic touch. Was just wondering if anyone found a way to fix it.
OK so, I recently decided to use my HTC One M7 as a "Modem" in this case, Tethering thru my Computer to my Main Modem, as my Computer keeps getting "DNS unavailable" stuff. Works great, only problem is that it freezes parts of Windows.
The Windows Task Manager doesn't load and is frozen (Usually doesn't when the CPU is under excessive load), the ENTIRE Control Panel of Windows is unresponsive, anything that has to do with Windows is not working, when it's unplugged they start working again.
Is this a problem with my Phone? or my Computer, It for sure can not be the computer as it works when it's unplugged.
Thanks!

update your USB drivers and chipset drivers and see if it continues
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?
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.
