[Q] TF101 USB > PC makes sound, but no sign of the device - Eee Pad Transformer Q&A, Help & Troubleshooting

I know that this theme has been beaten mercilessly, but let's try it again. Maybe someone can help.
I'm looking to breath some life back into my old TF101 with an update to KatKiss.
My serial number starts 037. I'm running 4.0.3 ICS. I have USB debugging enabled. I have MTP enabled. On the computer side, I'm running Win 8.1 on a Haswell i7 16GB with USB 3.0.
I have the original USB cord, and a new 3.0 USB cord from a third-party manufacturer. I've tried both cables. The TF101 itself is well-aged and somewhat beat up, but not beyond use. The cords work for charging.
When I plug the USB cable into the PC, the computer makes a sound, but no device is shown. The TF101 doesn't show that it's connected to the computer. I've looked everywhere: Devices and Printers, Device Manager (there's no "Other Device Listed"), under safely remove devices, and even under Computer Management > Storage > Disk Management. The TF101 is nowhere to be found. The computer does not recognize it.
When I power off the tablet, and try going to APX (or whatever) mode with VOL UP and POWER, nothing happens there either. (The computer shows nothing whether connected through the USB cable while Android OS is running, or while I'm trying to go into APX mode.) I can, however, go into recovery mode (or whatever it would be called) by holding VOL DOWN and POWER. I tried a factory reboot, but that didn't work either. The computer still doesn't see it.
Basically, I've concluded that there's no hope. Given this state of affairs, I cannot root my TF101, and, because I cannot root the tablet, I cannot install custom ROMs on it.
Does that about sum it up? Anybody else have any other great ideas?
I'd very much appreciate any insight anyone could give me.

Install the drivers on this thread and download Easyflasher
http://forum.xda-developers.com/showthread.php?t=1688012
Power off the TF while it is connected to the PC
Hold Power & Vol Up to enter APX mode
Device should be recognised by windows and hear the USB connect sound
Nothing will appear on TF screen
Run the Easyflasher and install TWRP
When done, boot to recovery to check you have TWRP recovery installed
If yes, copy KatKiss ROM to Micro SDCard in TF and flash from TWRP along with Gapps

Detection, I appreciate your response! The thing is, when I try to enter APX mode, nothing is recognized by the computer. I don't hear any sound. I don't see any new devices appear anywhere.
Should I conclude that I have the "TF101-is-not-recognized-by-PC Problem"? And, if I do, is there anything else I can do to about rooting and installing a custom ROM?
RJM

In device manager, try enabling "View hidden devices" and see if you can see the TF101 ghost entry, if yes, remove it and then plug the TF back in and see if it's recognised then
If you don't see anything that way, try viewing hidden devices with it plugged in too
There is no reason it shouldn't be detected in APX mode unless you have been unlucky and have 2 dodgy cables, or there is actually hardware damage to the TF
Try installing windows to a virtual machine too, see whether you can get it recognised that way
If you have access to another machine, see if you can get it seen on there to rule out hardware as the issue

Thanks for the reply. I appreciate your interaction very much.
I've tried it on both machines. There is no sign of TF101 anywhere, on either machine, as a ghost or anything else. I've looked under the Android section, as well as under Portable devices and every other list. There's definitely no sign of a TF101. No sign of anything that my TF101 might be posing under.
The only time I get any kind of response by the computer is when I plug the TF101 into the computer when the TF101 has Camera (PTP) mode activated. When I do that, I hear a little jingle. If I have the Device Manager open, it flashes. But, even then, I don't see any sign of it anywhere.
I'm totally stumped. Would there be some clear indication on the hardware that would cause the problem?
By the way, both USB cables charge just fine when I'm using the USB power box. But when using the computer, there is no charge or any other sign of the thing.
If you have any other advice, I'd love to try it!

The power and data connections on the USB lead are separate, so if you have a faulty lead, it could still charge, but not be seen by the PC
Something like this:
1: Power
2. Data
3. Data
4. Power
You won't see the TF charge from PC, it is only a trickle charge via PC, and the TF has to be powered off iirc, or at least the screen has to be off, so you only see the result, not the actual charge
Not sure what having the camera on is doing, I would still lean towards faulty USB cables being the issue even though you have 2 of them
Im guessing that the 2nd cable is a 3rd party cable, not a genuine ASUS TF101 cable ?

help! my sensation cant be detected on my computer

Yes I know some will say install drivers or slide down the notifications.
But the problem is when I plug in, there isn't any notification for you to switch to disk drive mode.
Everything was working fine last week. There was no problems detecting my phone on my home and any PC at work. I have drivers install in my computer and can do adb commands
But now, when I plug in, it only shows the charging light.
I have done the following
On and off the USB debug option
Reboot phone
Try a 4 micro USB cable
Tried different USB slots on the computers
Use usbdeview and delete all HTC drivers and resinstall also not working
Remove my micro SD card and reinsert.
All doesn't work.
Strangely, one thing does. When I plug in the PC and I need to reboot, with my phone still plug in my PC. The notification will appear and I can do all things normally. But once I unplug and plug in again, same problem. Only can be solved with next reboot with phone plug in before hand. If windows is already loaded, it cannot be detected.
I though it was the rom. But I went to boot loader and same thing. It shows fastboot AC. If I do the reboot windows method, it will show fastboot USB .. will show fastboot AC if I replug in
I am starting to think my USB port on my phone is faulty.. any ideas?
Try plugging it and wait for a long time. Since I formated my computer it takes like 10-15min for my phone to show up after I plugged it. No idea what's causing it though.
Done that , charged it for 1hr plus, same
Best thing is try different cable, there is some issue with htc cable your pc sometime dont recognize phone, Other thing you can do it is keep ur phone connected to pc then boot your phone to Hboot or bootloader or fast boot, your pc will recognize your phone with generic driver.

hmm tried 4 cables.. same results..
Using the same cable, tried my mum's desireHD.. no problems detecting the USB each time..
Bootloader mode, it shows Fastboot AC
instead of Fastboot USB.. unless reboot my windows..
Oh i tired another micro SD card, same results.. :/
why mess with cables... AirDroid.
connect your phone to the pc via wifi.
direct link to the market: goo.gl/9YG73
but if you must connect via cable for something... have you checked the most obvious place? (sounds like you probably have but just in case...)
settings > connect to pc > default connection type

Flashed ROM......
Mine is doing the same thing. It didn't start until I flashed the new ROM. When in Windows, I just un-plug it, and re-plug it. Then it shows up immediately. But it always seems to show in flashboot.

and if that isn't working try it with HTC sync. which gives you the drivers of the device.
I got the same problem... any idea...
please help me..
Is there where USB cannot be recognized issue? If this is, I have a simple solution which took me forever to figure out.
I know this method sounds ridiculous, but give it a try. Unplug your charger connected to your computer/laptop and plug it in to a different outlet. Replug the USB with your phone connected, give it a sec, and it should work.
what operating system is your PC running? I was gonna say perhaps it might be a faulty USB port...
i have the same problem
What I do is go to devices and printers and then android phone then properties then hardware and disable the reenable the drivers. As soon as you reenable the drivers it should show up in disk mode. Hope this helps. This is the only phone I've had this problem with.

[Q] USB Mass Storage Won't Connect

I upgraded to Sky-ICS RC7.4 Speed yesterday and today. Obviously the USB mass storage was working earlier because I got the .zip file for the upgrade on the phone. Well, just a little while ago I tried to connect so I could pull those zip files off just to save some room and it won't connect.
I can charge the phone, the laptop(Windows 7) and the phone both make sound/vibrate when connected. BUT, with I go to "Connect storage to PC" it tells me to unplug the cable, which it hasn't before but I did it anyway. I unplug the cable press the connect button again it states to connect the cable, I do. Press the button to connect and I get the same result. I've tried enable USB debugging and try again and it states to disable, blah blah blah.
It's great that I can charge the phone via USB all day long but really sucky that I can't access any of my files via my laptop.
Anyone had this issue or know of any fixes that may alleviate this issue? I sure would appreciate your help.
FYI, USB drivers are installed on the laptop and reapplied after the the issue of not being able to connect USB mass storage...
update: I am able to see the two mounts in computer management on my Windows 7 machine but not able to access them through My Computer.
I was reading from other threads about a possible Windows issue, how I find it unlikely, but I did a system restore from an earlier date and that made no difference. It's still a matter of the phone connecting completely to the pc.
Also tried different ports and usb cables, no avail.
I could really use some input so that if need be I can access the files on the phone to either flash back to stock or at least modify the files I have on there now to let me be able to attach my mass storage. I'm liking the the rom it's just a few little things like this that are making me completely love it.
i have the same issue if i plug in to the front usb ports. no problems with the back and its only been since i updated to seans latest speed stripped ICS rom
I was having the same issues. I turned the phone off, took the battery out, and then restarted it. It worked.

Correct; you need to reboot your phone because you probably connected / disconnected too fast and the phone is bugged out now.
I'm on 7.4 speed stripped and its working fine for me. Did you try installing the Samsung USB drivers exe in the dev forum?

computer does not recognize shield

i'm trying to connect my shield to my computer to do some basic android development (i have an app, it works on other devices, want to test it on the shield).
my problem is, when i plug it into the computer, nothing happens. to clarify, i don't mean that the drivers don't install correctly and then i can't do anything. what is happening is actually nothing. the computer (windows 8) does not recognize anything is happening, the device manager does not see any new devices even after scanning for hardware changes.
the shield is in development mode, and has usb debugging turned on, but i don't get any response anywhere. the shield does at least appear to charge over the usb cable, but that's it. listing adb devices also provides no output.
do you guys have any idea what might be going on that the device isn't recognized on any level that i can tell?
It sounds like either the USB port or the cable you're using is faulty.
Have you tried switching USB ports, to see if it's recognized then? And have you tried using a different cable?

If youre just trying to connect thru adb you need the universal naked driver. If the shield isnt being mounted try a different usb port and make sure youre using the shield cable as well. My samsung cable will charge it but i cant transfer data with it.
Did this get solved?
Did this ever get solved? I have the same issue. I have tried everything everywhere has said to do with no luck.

[Q] TF101 Definitely charged but won't turn on

Hey hey guys,
I got a TF101 off a mate to fix for him and I can't seem to get any response out of it :/ I've tried the usual:
Trickle charge
Normal charge
Power button for up to a minute
Power and Volume down
Checked with a HDMI cable
Stripped it to check the screen
When I plug it into my laptop it detects it but said the drivers aren't recognised(no idea why) and ADT doesn't see it
I've one myself so I've trickle charged it(the broken one), took it apart and disconnected the battery and put it in my dock and checked the battery which is around 50% ​
I've pretty much run out of ideas at this point! Any help would be much appreciated
Drivers won't be recognised until you manually install Universal Naked Drivers from this thread
http://forum.xda-developers.com/showthread.php?t=1688012
And use Win 7 32bit, as it doesn't require driver signing, or with 64bit/Win8.x disable driver signing from safemode options
Then stick it in APX mode (Vol up & Power from a powered off state) and try using Easyflasher from the same thread to flash TWRP (Nothing will happen to the TF in APX mode, but the PC should sound the USB connect sound and device manager show ! unknown device / ADB Device once drivers are installed)
If you manage that, flash a ROM from TWRP
But if there is not even an ASUS EEE PAD logo appearing, there could be bigger problems

Computer won't see my tf700

I have tried almost everything. Connected tablet to win7 laptop, does not see it, connected keyboard with tablet attached does not see it (even by other USB). I have attempted to add the device with device manager with not luck ....any other ideas?

Take another USB cable. You hear often, that data line breaks. I myself have one that you can only use to charge tab.
well the cable for the tablet only works with it...i did try another usb cable from the keyboard to the computer, but no go with that either
Did you
install the Asus sync utility?
check Device Manager for any changes when you connect/disconnect the tablet?
reboot both devices while connected through USB?
uninstall all old Android device drivers from your PC, reboot and try again?
If all of the above doesn't work, try this Linux live CD: http://www.transformerforums.com/fo...t/46090-guide-adb-fastboot-linux-live-cd.html

You didn't understand me. I meant with 'another cable' not a different one (there is none) but a new one, because the wires tend to break (physically).
Trying to reach device bootloader via keyboard port is not possible, because on boot keyboard is not intitialised.
The crucial test:
1. Open on Win7 device manager as an admin.
2. Connect tf700.
3. Is there a 'pling' and device tree changes?
4. If not, hit F5 (refresh).
5. If there is no change connecting to any of your USB ports, you might have a physical connection problem.
