Kindle Fire Not Showing Up When Connected to USB

Hey guys,
I've rooted my KF and got everything running. Haven't plugged it into the computer for about a week and now that I do, the KF does not show up and does not even make the dung dung sound when you connect up a device.
What can I do to fix this problem?
I have restarted both the KF and the computer without luck

Have you loaded the device drivers (that come with the ADB method)?

I assume so ... I believe that was required in order to root the KF? Any link on how to do it again in case something broke?

There's a few ways to get to promised land, and not all require the files associated with this process. Worth a shot:

Also, I assume the device is able to charge using the provided charger? Just checking the actual usb port...

Ya, the cable seems to charge but when plugging into the computer, there is no detection of a new usb device ...
Went through the video step by step. It's actually the same video I used to root. Get all the way till you plug in and have the device detect ... nothing. No where to go from there ...
Any suggestions?

Just connected the KF to a laptop and nothing shows up in the device manager either. No detection at all. WTF ...

Just tried a 3rd computer and no joy. Any thoughts?

This happened to me a couple of times where the Fire wasn't detected by the computer as a USB device and Kindle didn't pop up the mass storage message. After a hard reset it worked fine again. Hold down power for 20 sec and then hit power again to turn on.

Did a hard reset and still no luck ...

Just tried another cable ... it's not the cable ....

Can anyone offer any insight?

Have you tried a factory reset back to stock? Something somewhere is messed up, and it would end up being needle in haystack time trying to work out what the problem is. It shouldn't take too long to put things back to how they were post reset. If if doesn't work when stock, then you have potential hardware issues.
It's possible that one of the data pins is having issues on the Micro USB connector, especially if it still charges.

Looks like the USB port is hooped. It just stopped charging ....

Phone only charges on PC

Ok, I'm not sure what's going on, but my Nexus 6P will not do anything but charge when it's plugged up to my PC. I am using the systemless root and Franco kernel r7. Other than that, it's stock. What happens when I plug my phone into my PC is the battery icon changes to charging, and that's it. The PC does not recognize the phone is plugged in, and there are no unknown USB devices in device manager. I also do not get a USB notification on my phone.
More details:
- I have done the complete drive install VIA the nexus root toolkit (both initial setup before this problem, then again when the problem surfaced)
- USB debugging is enabled
- I swapped cables about 3 times, no change
- Tried different USB ports on PC and laptop and even ports directly connected to the motherboard. no change.
- Tried on my laptop (Windows 10) and it does the same thing as the PC (Windows 10).
- USB settings are set to MTP, although if I change it, it seems to get stuck on charging. I have to tap MTP about 3-5 times in order for it to say it's in MTP mode again.
- Running the command adb devices in command prompt does not show anything connected.
Other than this weird issue, I have not had any problems with my phone. I also have another USB-C cable on the way, but it seems unlikely that would be the issue.
*EDIT* For anyone who might have stumbled on this thread: I did not find any solution, and ended up contacting Google. They seem to agree this might be hardware related and have issued an advanced replacement.

Found this thread: http://forum.xda-developers.com/nexus-6p/help/usb-storage-windows-t3244905/page2#post63750876 but nothing has worked in it so far. I think I'm going to wait for the new USB cable then work on the laptop more since it's much less likely to have a bunch of other android drivers installed. PC has nvidia shield, tablet, and other phones at some point, I tried to remove everything identifiable in USBDeview

USB cable did not help. I also flashed pure nexus to see if it were some sort of ROM issue, no luck on that either.
Ideas? Anyone?

catlog post on USB port manager
I/UsbPortManager(950): USB port changed: port=UsbPort{id=otg_default, supportedModes=dual}, status=UsbPortStatus{connected=true, currentMode=ufp, currentPowerRole=sink, currentDataRole=device, supportedRoleCombinations=[source:host, sink:device]}, canChangeMode=true, canChangePowerRole=false, canChangeDataRole=false

windows 10 may be the issue. You might have to open the command window as "Administrator". Have you tried on another Windows 7 setup? I have Windows 10 installed, but it works for me.

If you have access to a linux install, plug the device in, and in a terminal window execute dmsg. The last few lines should show something about your device and report a device id. If that works, then it eliminates any hardware issues on the phone side.

Just tried on an old work windows 7 laptop, not recognized.

While it's connected to PC try turning USB Debugging off, then back on.

Tried that as well unfortunately. Also tried changing USB settings from MTP to various other settings and back to MTP. None of the modes seem to be recognized other than charging.

Only other suggestion would be to try factory reset.

I tried the factory reset, but no joy. I'm looking at possibly flashing images in TWRP to see if I can overwrite what might be causing the USB connection (if it's even software related). Beyond that, I guess maybe it's a weird hardware problem. If it were hardware related, you'd think that I would have issues charging or something, but nothing that I can notice.

Forgive me if this is way too obvious. Did you tap on the charging indicator on the notification shade and choose file transfer?
Edit: Sorry I just saw that you don't get a notification on your phone.

1. Have you tried uninstalling the drivers?
2. You should try uninstalling the drivers, turning USB Debugging off, install the drivers from Google directly(probably still the same from the toolkit), then plugging up the device.
I remember having problems with this on my HTC One V thanks to USB Debugging.

What did you end up doing for this? I'm experiencing the same thing, and I'm about to return my phone.

Fire Stick TWRP recovery using a mouse.

This actually works, ive done it myself, using a powered otg cable (homemade) i run the following command while plugged into mains and laptop :
echo 1 > /sys/devices/platform/bcmpmu_otg_xceiv/host
The device will disconnect from the adb mouse and you are free to plug in a mouse or most probably a keyboard also.
This would be a nice feature built into TWRP if this is possible, or even have it execute at the start up of TWRP for those of us with a powered OTG or willing to make one with a couple of old USB cables etc.
Obviously if the adb part of it disconnects it will be no use unless you have the OTG all plugged in.
Any thoughts on this ? its alot easier than using the adb mouse. Only not sure if this can be executed before the choice of system or recovery that comes on screen ? Cant see why not because you are connected as soon as that screen is up.
*EDIT
This does work as expected with a USB keyboard.

I suppose I could put a setting in the TWRP settings to switch between ADB and OTG. The only problem is if you put it in OTG mode, ADB will never work until you switch it back. But I guess as long as you can boot back in to the OS, I could make it easy to turn it off from there. And then I guess I could also make it so you could easily turn it on from the OS. I'll let you know.

I didnt want to tag you in this as you have already done alot for us all.
What I was thinking, (bare in mind ive no idea how to do ut myself, maybe if I had a little know how id attempt it)
would be to when TWRP boots and while its on the selection screen right before the timer is out if adb mouse has not been detected run that command, if adb mouse has been detected dont run. Have no idea if that's possible tho.

You know... I do like that. That's easy to do, because I already have a loop doing the countdown. So basically it starts out in ADB mode. Halfway through the countdown I check if there is an input device and if it's NOT the mouse emulator, switch the OTG mode. It'll take some tweaking, because right now the mouse gets disabled in the boot menu and I don't know the type of input device currently. But all that should be pretty doable.

Excellent, I was just messing around and made another powered otg lead yesterday and thought id try it while in TWRP. Was quite suprised when I ran the command then unplugged it from my laptop (still windows) ? then plugged mouse/keyboard in. Then had a think of how it could be implemented keeping everyone happy. I only made the otg to see if this fire stick would let me access usb storage, as i had a fire stick previously that let me read/write to usb, even had a hdd dock linked up to it too.
Unfortunately this fire stick wont let me access usb storage, no idea why the other was different.
Anyway great news ?

Authroize Broke screen ADB issue

Refer to this thread: https://forum.xda-developers.com/showthread.php?p=75551897
So Im waiting on a replacement screen (it started as crazy graphics all over screen, not completely blank, but responds to input), and its taking forever. I knew I had ADB debug enabled, so wondered if I can control the phone via PC.
Behold there are few ways this can be done.
Long story short......in adb, my phones shows as ADB DEVICES : UNAUTHROIZED
Is there anyway I can authorize the adb request between computer/phone?
Its a stock OnePlus 5.....so no custom recovery and not rooted :-/

You could guestimate the area or the enter button of the dialog, and use a mouse connected via USB otg to click it

Best way would be to use a displaylink adapter do you can see the screen.
If you can make it through the menus you'd need to install the app which can be done from a PC, just push it to the device, then advanced, then turn on usb, then allow the app. Then the screen will be shown on a monitor.
Either that or change the screen.

I got it working......I had to boot up an old laptop hard drive I had that was Auth'd. It let me do what I needed.

Toggling USB output via Tasker?

The only way to get a USB modem to work on Joying PX-5 seems to be to unplug and re-plug it into USB port after power-on. The modem simply doesn't connect otherwise. But it connects 100% of the time when unplugged and re-plugged. And after the car is restarted, we do the same dance again.
So... is there a way to automate this with something like Taker? I.e. turn the USB off and turn it back on? Joying is not rooted and I'd like to keep it that way if possible?
Perhaps there's another solution? I've seen USB cable with a physical on/off switch. I could use that, but it's not the most convenient way as Id like to keep the USB modem hidden out of the way.
Any hep, ideas?

Dig into developer settings. There may be some options
Sent from my Nokia 7 plus using Tapatalk

Can't find anything in developer settings. Tasker doesn't seem to allow anything similar. I'm almost thinking of creating some sort of a hardware timing latch and do a reset on USB line about 30 seconds passed boot-up.
Has anybody seen any solution for this at all? I mean, there's got to be a way to simulate unplugging and re-plugging the USB device, no? Please help!

Nope. There ae some USB short cables with a switch out there, but the car this was intended for is currently parked in... Bucha, Ukraine, so I wouldn't see it any time soon...
