I haven't taken the plunge into the world of android (yet). I am just using my B&N NookColor "as is". My problem is that after I transfer a book from my XP desktop and disconnect the NC, my PC keyboard won't work until I reboot. (Yes, I first clicked on the safely remove or eject or whatever it is called thingy) I contacted Nook support and they said I needed to contact Dell (I haven't tried that yet). I am just wondering if anyone else is having a similar problem.
BTW, I think I will try rooting eventually but at the moment I am still a chicken. This is my first android device. I am reading up on it but I'm having some difficulty with all the abbreviations and "geek speak". At any rate I would like to thank all the people who have worked so hard this project.
Did you try to unplug the keyboard?
I had something funky happen with my Chinese knockoff Haipad G10 running on 2.1 Every time I connected it my keyboard and mouse would behave very erratically, stutters, stops, things of that sort. Both are wireless. Unplugging the G10 would bring them back to normal.
Not that this is the same thing, but Android is the common denominator here.
As I suggested, switching USB ports should fix it without the need for a restart.
I had something similar happen when i plugged in my nook for the first time, all my usb stuff went nuts and died until the nook had succesfully mounted as a drive, i think it might have to do with the charging voltage it pulls. couldnt get things working until i unplugged them and replugged them with the nook disconnected.
Thanks for trying to help, devis.
This is what I just did: connected NC to PC and moved a file. I properly ejected the Nook and then pulled out the Nook usb cord from the PC. At that point, my PC keyboard wouldn't respond. I removed the keyboard usb connection and put it into a different usb plug. No joy!
Perhaps I misunderstood or perhaps the problem is deeper.

for the past few weeks i have not been able to connect my phone with any computer using any cord. all are either vista computers or they have active sync 4.5. at this point i have reached the conclusion that the problem lies with the phone itself. i may have deleted the whatever it is that runs the usb on the phone.
any suggestions or past experience would help. i don't really feel like spending money on a new one. it gets frustrating when many mods are done from (or at least started) on the computer, and then require my to connect my phone.
btw... i have synced the phone many times before the problem started using all the same components i am trying now.
EDIT: the battery icon shows it is charging when i plug it into a usb, but from there, i have nothing, and i have also reset memory a few times since then too.
Thanks again from a modding newb!

How are you trying to sync it? Plug it in and wait for Active to launch? Launching Active yourself and clicking connect, or from within the phone itself?
I wonder if disabaling USB charging would allow you to sync it up again.. Have you reinstalled the computer software from the CD again?
I am sure there is something you can do aside from a full phone reset...
At first, i just plugged it in, like i do every day, and wait for active to launch, but it didn't, so i opened it manually.
I tried reinstalling from the OEM disk, and also downloading directly from Microsoft (both AS 4.5).
ill poke around and see if i can disable USB charging like u suggested. thank you.
Edit: It looks like this is a hardware issue and I'll likely try to get it replaced via insurance since I cannot revert to stock using Odin. It is impossible to revert without using Odin right? Thanks to all who read!
To start, I just want to state that I've searched and searched for answers/information on this (not just on XDA forums either) and I haven't found a similar issue - my sincere apologies if I missed it.
Quick "this post is way too long to read" Summary:
1. Phone will not charge
2. Phone will recognize PC connection via USB but with no functionality
3. PC will not recognize phone
4. All details on what I've done so far below
Friday 3/4/11 - I used a USB car charger (link below) to charge my Captivate with a USB cable known to be working (had worked on my Captivate before, works on my brother's Captivate). If you're asking why I used that charger... well I got it for free with my E-71. I'll never use it again. Anyway later that night I tried to charge my phone on my official AT&T A/C charger but nothing happened - the phone acted like no USB was inserted.

Sorry for the bootleg link, this certainly isn't spam but I'm not allowed to post links yet.
Since that date, my Captivate won't charge via AC power cord. My PC won't recognize it either, but here's the weird part - my phone recognizes when it's connected to the PC via USB. For example, I can connect the phone to the PC and it will state "USB connected" on the Android pull-down (top) menu. Since I have mass storage chosen as the default, it will give me the option to send or receive files from the PC from the same menu. However, if I attempt to actually take that option, the pop-up menu which allows you to mount your memory cards does not come up. In addition, if I have the phone in USB debugging mode and I connect to my PC, the phone recognizes that as well. The PC does not recognize the phone in any capacity, at any time. No matter what I've done so far it will not charge via A/C.
Background: I've had my phone for a little over 6 months now, I've been running Cognition 2.1.6 since about 3 weeks after I got it - before this problem I haven't done any modifications whatsoever since the first load of Cognition. My PC is Windows 7 Ultimate 64. To rule out a bunch of other things, I've tried to use multiple USB cords that are known to work with a different Captivate and my Captivate prior to this problem (3 to be exact), I've uninstalled and reinstalled all Samsung's drivers on Windows, and I actually reinstalled Cognition using the three button recovery mode. To further rule out external problems, I just put Serendipity on my brother's Captivate using the same USB cord and PC that I'm attempting to use with my phone. He had been using the exact same version of Cognition I was.
I of course tried to revert the phone to stock using ODIN in order to fix the problem. I attempted to use the two button method (hold volume keys and insert data cable from PC with Odin running) but of course since the USB is not working properly that didn't work. It's worth noting that the described method worked perfectly for my brother's Captivate to revert to stock in preparation for installing Serendipity. I attempted to manually unmount and remount my memory cards several times, change USB modes between mass storage, Kies, modem, etc - nothing seems to work. The phone seems to be completely normal except for this USB issue. One last thing that's strange is if the phone is powered off and I have the USB A/C charger plugged into it, I cannot turn it on. When I hold the power button a relatively small spinning circle comes up after a second or two near the top of the screen. It disappears when I release power. If I remove the USB cable and hit power again it powers up completely normally.
Because of all of the above, I'm 99% certain that the issue is with my phone (not from any other external source). My only uncertainty is whether this is a USB hardware issue or a software issue where the phone is trapped in some sort of limbo due to being in a quasi-data mode which is causing it not to charge via A/C power and causing the PC not to recognize it. Has anyone had an issue remotely like this? I've come to terms with the sinking feeling that this is a hardware issue and that the only option I'm going to have is for my phone to be accidentally run over by a car (in order to pay my $125 and get a "new" phone under AT&T insurance). If anyone has any suggestions I'll be more than happy to try, maybe we can get this thing fixed!
If you made it this far I'll just say thanks for reading my wall of text and thanks in advance for any advice you have.
Were you able to get this issue resolved? It just started happening to my Captivate earlier today, and I was hoping that a solution had been found.
I haven't been able to get it resolved, I actually just sort of gave up on it and went back to my old phone for now. I have insurance so I'm not totally screwed, but it's not that cool obviously.
Were you able to get anything resolved on your end? If so I'd love to hear how. The one good solution would be a package to restore to stock that you could run through update.zip on a memory card, that isn't available yet is it?
i have this issue as well. I flashed Cognition 4.4 and it ran just fine for a couple weeks and then it began not even recognizing the micro plugged into any power source or the samsung dock! debugging on or off, battery saver apps removed, all that. multiple reboots. nothing. it takes a spell of, if i'm lucky, recognizing it after i eff with it for a few minutes and flukes a decent charge but at night, it usually has a loop cycle charging effect. I can hear the "boop beep" charger plugged in sound over and over throughout the night.
i use the phone in my cars and everywhere with the same problem.
no resolution! HELP!!!
I came across the same problem with USB on ARMANI I9010 after installing Cognition5. The most unpleasant is that i have bought it abroad and there is no possibility to return it
Does any body found the solution?
Hello,
I unlocked my device by using ASUS unlock tool. Everything went well. I also can see the message "Device is unlocked".
Then I tried to connect my tablet with my computer to install TWRP and further a cutom rom, but this is not possible. If I connect my tablet with my PC nothing is happening at all, means tablet is not recognized at all. I'm using Windows 10. Anyway, my mobile phone is recognized. I already tried to set it back to factory settings, flashed the latest Asus ROM, but nothing helped.
The other curios issue is that the tablet is not able to recognize that the battery is charged. LED is lightning and battery is charged, but tablet says power adapter is not connected.
Any idea? Could it be the cable? I already tried to connect the table over the dock, but same behavior. Dock LED is lightning as well.
I'm really frustrated. Hope anybody can help. I really need to establish the connection to my PC to go ahead.
5.11.15 - Update:
I realized that it seems to be an issue with USB. As mentioned above USB to tablet is not working (no PC can recognize it). If I connect the keyboard no USB device will be found. Charging the tablet is also not working, except I connect the power adapter and cable directly. Any idea?
Thank you.
Hi, I am having the exact same issue with my TF701. Were you able to resolve yours?

Duchman or Dutchman? I'm having again exactly the same symptoms. Tried 3 different USB cables too. Dit yóú manage to get this sorted? I know it was 4 years ago but my TF701T is still working properly, for the most part.

That is exactly the same behavior. Best for now is to charge with the device powered down. I'm about to open up mine to doublecheck if the USB connector is seated properly.
Weird thing is that the keyboard also fully works which should not be possible if the USB port on the tablet was malfunctioning right?
I'm having a lot of apps not displaying anything anymore so was going for the KisKatt rom to see if that fixes the lot. Also I see after some time some apps keeping the device awake all the time so battery is always drained when tablet is closed.

My TF701T is sitting disassembled in one of my drawers after an unfinished screen replacement attempt. I did manage to install TWRP on it, however, I don't remember what I did exactly to accomplish that.
I might have used one of those shady rooting apps that I'm not sure if I'm allowed to mention here. Then I probably flashed the TWRP with Flashify. Basically, circumvented having to connect the device to a computer up to the point where I had a working recovery on it.
Don't ask me for the exact steps because I wouldn't be able to remember anyway. I'll lay out a basic plan of action:
1) Find an app that lets you root your device without connecting it to a computer. Be warned, those more often than not come bundled with malware, so exercise caution. I'd back up all the important files and information and do a factory reset before attempting this if I were you.
2) Install Flashify, grant root access, download TWRP zip on your tablet, flash. Do some research on how Flashify works and how to use it before you attempt this.
Good luck, and if anything comes out of this, be sure to come back here and report on what you did in case some other poor soul wants to install a custom recovery on their 7 year old tablet without using a USB cable.
I just had mine crap out for some reason and needed to reformat everything and re-install. Connecting the USB to my PC, the PC makes the connected sound but no drive or anything showed up. I couldn't be bothered to figure out why so I just used adb to put the files on the tablet.
adb push yourfile /sdcard
I just got my first Raspberry Pi device (Pi Zero) yesterday. I installed RetroPi on it. I followed the step by step instructions, to the T. Formated 32GB Class 10 SD card in Fat32. Installed the OS. Plugged it into my Pi Zero. Hooked up my controller and HDMI then hooked power. It installed Retro fine, boots, and during controller configuration, it freezes.
I've tried several different power sources (I'm using my S7 Edge wall charger right now), I tried removing my USB hub and running just a single controller, I tried different controllers and brands, I've tried redownloading the RetroPi image file (and checked MD5 sum), tried formatting the card multiple times and installing fresh OS. End result is always the same. Freezes up during controller configuration.
You can see the little green indicator light on the RP0 stop flashing when it happens.
I also tried installing Raspbian, which worked and booted. I was able to use my keyboard and run commands. I powered it down via command keys and unplugged it. Wiped the SD card again and try RetroPi image again and now I'm getting no display at all. Tried fresh OS again with same results, light blinking so its reading the SD but no display.
I'm at wits end and I honestly want to just smash it into little pieces at this point.
Any help would be beyond appreciated. I don't know what else to try and I want to cover all angles before I request a return.
Thank you.
Hello everyone,
I've come across an interesting issue I haven't seen before and was wondering if anyone else has seen this happen. I just got my X Fold the other day and was trying to remove the bloatware with adb on my computer. When I plug it in and enable USB debugging, my laptop hard crashes, just immediately black screens. It then takes a couple of attempts of it turning on, then shutting off before I can boot, before I finally comes back to life and is acting normally. I've never seen this before or heard of it happening, anyone have any idea what's going on? I wiped the phone when I got it so it's not like there's some malicious code from the last owner, unless it's built into the system? Although I have a feeling it's something more mundane like an incompatible driver.
Update: I've discovered my USB ports no longer transmit data. All of them can input/output power, but anything with data like a USB drive or my Ethernet adapter don't work. This is really odd...
Hello, how can I add the question hashtag in the name like you?
