[Verizon Samsung Galaxy S III] cyberkeeper1:
OK so here is a complete and simple rundown of the events that led to the demise of the USB nonsense. i think... Honestly, I do not have a definite answer or clue as to the cause of this, directly or indirectly. :/

First, Lets get the redundancies and silly questions out of the way first before they can be asked. I believe in the expedition of things for faster service and for clarity.

System Specs for reference:

HP Pavilion DV6780SE Laptop

Partition 1:

..................................

Partition 2:

Windows 8.1 Professional (64-bit) / Linux Mint 17 (64-bit with 4gb swap partition)

4GB RAM

128GB SSD

1. I have freshly installed 4.4.2 via ODIN with a FULL WIPE TAR file. like FIVE minutes ago as of this post timestamp.

2. USB Works while using ODIN but not when i boot into the OS. Safe Mode and regular make no difference to this effect.

3. I have all the proper drivers, ADB versions and what not preinstalled on my computer, AND i am only using USB 2.0 (i know better than to use 3.0) Drivers are provided by universal naked driver here on XDA, and i have previously used the USB successfully with this phone.

4. Finally, regarding the successful usage of the USB while booted, it ONLY worked before i upgraded to 4.4.2. i had full access in 4.3 and below. Now only ODIN works. Is there any process or explanation which fixes this issue? its really annoying to use Kies Air with a less than adequate router and its only 54 Mbps... thats 9 times slower than USB which is 480 Mbps.

Alright. On to questions... What would cause a previous version of android for this device to have a fully functioning USB subsystem and after the upgrade, stop working. I'll mention once more, i'll FULLY wiped the phone using an original stock TAR file aimed for 4.4.2 android AND used the PIT file for this device and corresponding capacity, just in case the partitions were messed up somehow.

We should discount any factors pertaining to hardware issues because I've already proven that it works in ODIN, and multiple stations and USB cables have been used with the same result. Only ODIN works.

Upon booting, for a split second i see my device manager light up something, but it says "unknown device (bad descriptor request)" and disappears. this happens exactly twice before the boot sequence commences. AND, it only happens coming from ODIN mode, and not during a reboot, to my knowledge. I've tried going into ODIN mode with the cable still plugged in, and then rebooting with a battery pull and a press and hold power attempt, and still nothing. This has worked for some, but not for me. Its simply baffling... When the phone is fully booted, nothing shows up in device manager. the list does not refresh or show any uninstalled devices as it normally would with other USB devices i own. Insertion or removal or any device warrants a visual list refresh. The whole device tree normally collapses and expands again on its own at this point. :confused: :rolleyes:

I request some major help with this. this whole thing is quite the nuisance. I cannot do anything with my phone at all, even ADB usage which I need in the hopes of moving to a custom ROM or otherwise. The option simple isn't possible at this time.

Any suggestions? ANY!? :crying::confused::rolleyes::eek::fingers-crossed:
