[Q] New motherboard - New USB problem! - Kindle Fire 2 Q&A, Help and Troubleshooting

I bought a new kindle fire 2 motherboard as I managed to hard brick my old one (long story!).
This new motherboard works perfectly and my kindle fire 2 works just as it should....except.......
When I connect to a PC, I get a "device not recognised" error. When I check under device manager - it is listed under USB controllers as :-
"unrecognised device (Device descriptor failed)"
Now I know I have correct drivers installed as my other kindle fire 2 works perfectly - both in normal ADB mode and fastboot mode.
Wondering if I have bought a duff motherboard? or can this be fixed? Is the USB comms handled directly by the kindle's processor?
I did wonder about the USB socket as I have read about the problems with these, but I had a look at the socket and managed to find a few exposed pads and managed to solder a USB cable to it, but ended up with exactly the same result!
On the one hand I'm very happy to have a working Kindle fire 2 again, but a bit peeved if I cant do anything with it!! (other than use it as a kindle fire of course!)

[Q] Stuck at welcome screen and cannot access Kindle in Windows

I have had my Kindle Fire for a week after bought from a friend, it had been installed CM10 ROM http://forum.xda-developers.com/showthread.php?t=1778010.
When i try to play some HD game with my KF, i try to install Chainfire 3D, after i install CF3D Driver (part of Chainfire 3D), my KF reboot then stuck at Kindle Fire welcome screen (white - orange kindle fire logo).
OMG, this my first times I’m using an android device, I try to plug the Kindle into the USB port on my Laptop (Windows 7) by Blackberry phone cable, it will only recognize the device in My Computer as a regular disk drive. An entry for "Removable Disk G:\" drive comes up, but when I click to open it, it says, "Please insert a disk into Removable Disk (G:\)". I copied a video to KF before it stuck.
After read a lot of threads, i know what i need to do is try to make my PC recognize KF device. I’ve tried install driver from KFU folder, Kindle Fire USB Driver and Google USB Driver from SDK Manager, rebooting the KF, unplugging/plugging it in each USB port, power off before plugging, rebooting the PC, etc.
I try to make a factory cable, nothing better (I think it just be useful if the PC can recognize KF device).
At Device Manager I have “Amazon File-CD Gadget USB Device” (when using factory cable, it will have “Unknown device” instead of “Amazon File-CD Gadget USB Device”). List of devices (Device Manager window) don’t have Kindle or Android Phone (when I try to add Android ADB Interface, Android Bootloader Interface, Android Composite ADB Interface by legacy hardware it have a yellow exclamation point)
At Devices and Printers, the properties of the Amazon Kindle Fire's hardware, it just list: Amazon File-CD Gadget USB Device and USB Mass Storage Device (don’t have Kindle, USB Composite Device as some Guide website).
Does anyone have any idea? I don’t think KF device can be bricked easily by install a driver that not compatible with ROM!

Kindle Fire not being recognized at all.

If this is the wrong forum, please move as needed and I apologize.
I recently purchased (2) refurb'd 1st-gen Fire's with the intent of loading CM10.1 on them. I don't know what version was on the first one, but the second has 6.3.1 on it.
I downloaded KFU 0.9.9, the CM zip, the gapps zip, and after some playing around, was able to make it all work on the first Kindle, via a Win7 laptop.
When I plugged the second Kindle in (same laptop, same USB cable,) it was not recognized. I then plugged the first, now-flashed one back in, and it wasn't recognized, either (within KFU.) I checked the device manager, and the Kindle had the yellow triangle of doom attached to it, but it at least showed up. I again plugged the second unit in, and not only is it not recognized by KFU, it's not being recognized as a connected device within the device manager at all. I can't view files on it, nothing.
I then tried installing KFU on a second laptop, and got the same scenario again. I tried downloading a different KFU utility, no luck in either case.
Am I doing something completely wrong here? I just want to get CM on this second Kindle, and nothing at all seems to be working now, after the first one seemed to go pretty smoothly.
Thanks

Try re-installing the driver

Sorry, forgot that in the OP.
I reinstalled the drivers using install_drivers.bat several times (each time it says successful.) I also uninstalled the "working" device (Kindle 1) from Device Manager and then installed the drivers afterward. No change.
I called Amazon support earlier this evening, and (but of course) the device is out of warranty. They recommended that I called the company that I purchased them from (Best Buy,) but the 15-day return window has passed so I'm assuming they'll tell me to pound sand.
On the call, I did ask whether or not there was a newer system version available (this is on 6.3.1_user_4107920) and was told that there is a newer version, and to let it sleep for 2 hours without interruption and it would find it. Several hours later, it's listing as no updates available. I thought that maybe if there were a system issue, an update would overwrite the problem and I'd actually be able to see the device in some way. So, with no cable and no auto-update, I manually installed the .bin (via Amazon's updates page, but I don't have enough posts for external links) and ran it successfully. The device was updated to 6.3.2_user_4110520, but is still not recognized in any way, beyond the fact that it charges, as indicated by the battery icon.
I'm going to stop by Best Buy tomorrow, but I don't imagine they're going to try and help me out.
The idea of the USB port being bad crossed my mind, but because it was charging I disregarded it. After running out of realistic ideas, I finally compared the two USB ports. The flashed, working unit has a pristine-looking port, while the problematic one looks mangled. I tried to ever so gently straighten and isolate the pins, but the connection may be severed at the base where I can't see it.
I'm fairly sure this is the problem. After doing this, and holding the cable just so, I was able to get the device manager to update, although not what I wanted. When it updated, and recognized the Kindle to some degree, it actually dropped connection to my mouse. When I let the cable go from where I was holding it, the device manager recognized my mouse again.
So, yea, I guess a trip to Best Buy is in order.

So... you think the USB port on the tablet is bad? Or you think the USB port on the PC is bad?
I'm having a very similar problem with trying to root a second KF. First one rooted just fine. Installled CM10, gapps, the works. Go to try and do the same thing, and it won't work.
I also tried it on another PC, and it didn't work on that one either. That other PC however is an old server PC that I forced Windows 7 on, and it has some major issues, so not really a reliable PC.
Now the PC I'm on is too old, I'm gonna need to take Windows 7 off of it. A recent update rendered my PS/2 ports obsolete, and I'm not PC-literate enough to know how to roll back a KB file. Linux it is.
...speaking of; have you tried connecting the KF/rooting it via Linux? I have a bookmark for that somewhere. Lemme see if I can find it... or link you to it:

Have you seen that thread?
The drivers that come with KFU always caused me problems to no end. I would suggest you uninstall them and install the Windows 8 drivers I supplied
http://forum.xda-developers.com/showthread.php?t=2185402
Sometimes (don't know why), you need to mount your Kindle for it to be detected. If you've booted in recovery, mount the usb drive. If you're loaded inside the ROM, turn on debugging.
need these drivers, site doesnt redirect properly

kindlefire not seen by computer FIX
I have 8 different Kindle Fire devices for my family. I tried to hook my daughter's best friend's Kindle to my computer so I could books on hers through Calibre. My computer couldn't see her Kindle. I tried different ports. Nothing. It could see all the other Kindle devices just fine (HD and non-HD alike) - just not hers (a second generation Kindle). I dug for hours trying to figure it out. At last I stumbled upon a post that helped. This is what I did and my computer sees it fine and Calibre is working beautifully with it.
Systems I used:
Windows 7 Home Premium SP 1
KindleFire Gen 2 System Version: 10.5.0_user_5060020
DISCLAIMER: Messing with device drivers is NOT for the unexperienced user, and can much mess up your computer beyond the point that the same user can repair it. I cannot take responsibility nor offer help if things go wrong beyond your capability to repair it.
Connect your kindle (as normal- you don't need to slide to unlock or anything... just connect it)
Open your Device Manager: Click Start -> (search) Device Manager
If your device was not recognized, a device with a yellow exclamation mark will be listed under Other devices. Mine was just listed as "mtp".
It stated that there were driver issues including an MTP issue.
To set your Kindle as a Kindle portable device, do this:
Right-click the device in the Device Manager and select Uninstall. This removes the current driver, and provided you disabled automatic driver installation, will leave it as a unrecognized device with the yellow exclamation mark icon under Other devices. You may have to unplug and replug the Kindle after you uninstall it in order to see it listed under the "Other devices".
Right-click the device again and select Update Driver Software ->Browse my computer for driver software -> Let me pick from a list of device drivers on my computer.
You should now have a large list of common hardware types. Here, scroll down and select portable devices -> Standard mtp device -> mtp USB device under the Disk drive.
You will be prompted to confirm this selection, click Yes. The Kindle will now be recognized as a portable device listed as "Kindle" by your computer.
Calibre sees it fine. It is now listed under my "My Computer" as a portable device sublisted as a Kindle.
Doing this did NOT change how my computer saw my KindleFire HD 8.9. It did not change anything EXCEPT the particular Kindle that would not be seen previously. I hope this helps some others who are lost figure out theirs as well.

Bricked Kindle Fire having difficulties connecting to ADB

Hi all,
I've got a Kindle Fire, which was rooted quite a while ago. More recently, I had the 5 second bootloop, so I took the kindle apart and charged the battery directly by cutting apart a micro usb cable. This worked and now the device powers on, but is stuck on the logo. I previously had all my drivers set up for kindle, and ADB was working properly, but now it shows up as an unknown device. I have tried reinstalling my entire Android SDK, with Amazon's repositroy added, and have uninstalled the drivers on the Kindle, so that only the Amazon ADB drivers remain. Still, I am unable to connect with ADB, and the device still shows up as "Unknown Device" and fails to be noticed by Windows7, or ADB.
Can anyone point me in the right direction please? Thanks!
P.S. I've tried the KFU.

install drivers that are included with KFU
then
In Device manager>select unknown device>Update driver software>
browse my computer for driver software>Let me pick from a list of Device Drivers on my computer>
show all(uncheck show only compatible)>look for ADB interface or android phone
select yes to Ignore warning
may need to reboot both.

+1 to above response. Tell windows to look for similar installed drivers and choose the ADB interface drivers.
Thank for the quick response. I tried what you told me, and I notcied that when I plugged the Kindle in, and listing of "Android phone" popped up in device manager. It then immediately disappeared. After a little dinking around with the cable, I found that the micro usb port on my Kindle in loose on the inside. It wasn't making a proper connection. So I'm charging it right now with the cable slightly angled in the device. Thank you for the help anyways!
Any ideas what I could do to fix the loose port? Solder?
soldering should fix it, several YouTube videos on it.

[Q] USB device not recognized and wireless can't on

I have a kindle fire which wasn't doesn't connect to the computer. I get an error message such as "USB device not recognized". I had rooted the kindle fire and I thought that this problem could have been because of the rom or some kind of kernal error so I installed the stock rom thinking that I will just re-root if however the connection problem still was still there. So now I have kindle fire which is not rooted so doesn't have google market and I want to root it however cannot find a way to get it connected. I have tried 3 different computers and many different cables however still no success. I have also tried reinstalling the drivers, turning off and on the kindle fire with the cable plugged in. Could the port on the kindle fire be broken even though it charges fine. Also, would a factory cable help because I don't want to order it if it doesn't work. What other options do I have? I live in UK and this kindle fire is the 1st gen which was only available in US so cannot send it to amazon for checking.
And wireless is can not switch from off to on.
Your help will be appreciated

Is there a general way to manually update drivers? (In my case, USB Controllers)

Hey all,
Just wondering if there is a way to manually update drivers for Fire TV/Stick/Android in general? I know this is an odd build of Android TV, but it just occurred to me after all my years of using Android, I have never had to try to update drivers. Recently I purchased two classic SNES controllers (USB) to use with my Fire stick via OTG adapter. I was unable to map or recognize X,Y,L, and R buttons. All other buttons were recognized and functional (select, start, A, B, D-Pad). I checked on my android phone (Note 4) and same issue. I then checked on my PC and the buttons were recognized. I then checked on my Nvidia Shield TV and it was again recognized, making me think it was a driver specific issue. Thanks in advance.
