When you open device manager does it show up but with a yellow exclamation? Does it show up as unknown? You haven't given much to go on.

do you have a dock? plug the usb to your dock and see what the device manager on your pc says

I had this exact same problem. I grabbed a new cable, tried my gf's cable from her tf101 and nothing seemed to work. I updated the firmware to ICS hoping that fixed it and notta, then updated to JB and that bricked my tablet. Prior to all that I couldn't get my pc to recognize my tablet. After I RMA'd it and received it back guess what - it worked
Whatever they did on their end fixed it. The only thing slated on the receipt was reinstalling the OS so there was no hardware replacement. I'm thinking that a full wipe and install might do the trick if it happens to me in the future, if this is what they do in their facility.
Hope that helps

[Q] Transformer Prime won't connect to win7 PC

I've had this awesome tablet for just a day and loving it so far. Only issue I have right now is when I connect it to my Windows 7 PC, it is not detected at all. I have installed the PC suite (EeePAD_PC_Suite_v1_0_37.rar) which is suppose to install the requisite USB driver, but no luck.
It charges fine when I plug it into the wall so the wire is okay. Any ideas what maybe happening?

Most phones come with the drivers on them to install most functions when plugged in via PnP. I would test and see if uninstalling what you installed and then trying does. I could be wrong though. This is my first tablet and I don't have it in hand yet
i noticed that mine doesn't charge yet it does connect...make sure you restart too
I was told it will charge just at a much slower rate.
Problem solved. I did a bunch of things so I'm not exactly sure which one really fixed it. But rebooting the tablet seems to have done the trick. Also, the front USB ports on my PC have gotten a little strange. If I plug the USB connector all the way it wont work. I have to pull it out ever so slightly to get a successful connection.
Thanks for the quick response guys
No Matter what I install It still shows as an MTP device and that's it. Can not see it in any version of Windows.. any one have this issue. thanks
I got mine to work by using another cable.

Prime USB 2 PC not connecting

Hey yall,
I got a quick question. My Prime for some reason will NOT connected to my PC as of this afternoon. Ive tried connecting to multiple PC's afterwords and none of them would detect the Prime at all and vice versca as my Prime would not pull up any notifications showing that it was connected. I have the Asus sync drivers installed and I know this becuase my Prime was plugged in to the PC and I was able to view all my internal memory files and was about to push a file to it when it just stopped communicating.. any suggestions would be helpful and I will give thanks.
Im already factory resetting and restoring from a nandroid..i will update and find out if it works once the restore is complete...
Yeah ...that didnt work. I even went as far as factory resetting and starting from scratch but it does not work anymore. Anybody care to jump in?
OK now my prime won't charge at all unless the screen is off. Does anyone know if this is a charger issue or prime itself???

Could be a charger issue. Do you have a dock? you can try hooking it into that first.
Inspect the charger cable, look at all the connections and see if any of them look broken or bent

How to connect to PC

Is there anything I am missing here? I cannot for the life of me get my Prime to show up as an external storage device. Also it will not charge when connected to my PC. Charges just fine with the regular charger.
should show up as a MTP device. I wish i could have it as an external storage device, im interested in this as well. Anyone know how to do it?

Incorrect, the prime charges fine over USB, as long as it is USB 3, my laptop charges the prime just fine.
USB 2 and previous do not output the power needed to charge the prime, the prime needs at least 11.1 volts to charge, the adapter puts out 15 when connected to a USB 3 cord, but a perfect 5 volts when connected to a USB 2 cord, so your phone is fine to charge on that charger as well.
As for connecting to the computer, check out Samba network fileshare.
It works perfectly for browsing, there is even a hack to allow you to browse your root directory as well if you have root.
However natively it only connects as a media device.
Thanks for the replies!
Well that sucks big time.. transferring movies over WiFi takes for eeeeeeeeeeever. Can't believe it's not supported as external file storage. Oh well.. get my dock tomorrow. Should simplify things I hope.
I guess you can't connect the dock to a PC to transfer either?
That is correct, the dock adds no special abilities.
Use an SD card adapter, put the car in your computer and transfer that way, as fast as it can possibly get.
Does any of the custom ROM's allow the device to be recognized as a storage device? This would actually be worth it for me to unlock my boot loader.

My TF201 is recognized as media device named Transformer Prime TF201 in Windows Explorer and I can manage the memory storage without problem.
Is the right driver installed on your pc?
You can also use AirDroid (free on Play Store) to manage your files. But it's through Wi-fi.
Btw: my TF201 is rooted. I don't know if it make a difference.
I second the advice about charging. No charge when i plug to my pc (USB2), charging when plugged to my notebook (USB3)
Usb3? Sure, if you got it.

That's not true. Like pnoire stated, you can get your TF201 to be recognized as a media storage device. And also like you, when I first tried to connect my new TF201 to my pc, it wasn't even detected as plugged in. After a few tries, I figured maybe that USB port was bad as I've known it be kind of bad from time to time. So I tried a different port. This time my pc detected it as being connected but then it was listed as "Unknown device" under Device Manager. After some Googling and searching the forums, I ran across the thread about the Universal Naked Driver Beta in the development forum and it mentioning that some USB drivers for some Android devices conflicting with others. Since I had installed the Samsung USB drivers for my Samsung phone, I thought maybe that's what was causing the problem. I proceeded to uninstall the Samsung USB drivers and then retried connecting my TF201. Sure enough, my PC detected it again and proceeded automatically install the drivers it found from searching the internet and VOILA! My TF201 is now a working media storage device displaying both the internal sdcard and my microSD card I put in it.
Long story short, try uninstalling any other Android USB drivers for any other Android devices you might've installed earlier. Sometimes the only way of uninstalling the drivers is to first connect that device to your PC and uninstalling the drivers while viewing the device in Device Manager.
I'm not entirely sure how much help this will be but I had the exact same problem as the OP when I got my prime 2 months ago. I looked everywhere and found a solution although unfortunately I couldn't find the solution again after just trying to link you to it. Go to the device manager and find your prime listed as an MTP device. right click and go to properties. I'm pretty fuzzy on this so bear with me. You should have an option to select driver from a list. click that option and you'll have a ton a driver options to select. Look for the driver called something like "Universal MTP..." and install that. I was able to browse all internal storage on my prime after I did that and it would auto-connect like any other USB device once I plugged in the prime there after. Good luck!
I don't know if this will help or not, but when I tried with mine it wasn't recognized either. So after trying a couple of times I tried wiggling the usb end of the cable going into the PC and bingo it shows up as "Transformer Prime TF201" and I can transfer files no problem.
Hope this helps.

I am confused. My normal state. Do you use the cable that is the charger cable or do you need a micro USB cable.
Thanks.

The charger cable that came with the Prime.
I had this problem with MTP drivers being screwed up on my computer and several devices wouldn't work correctly.
I Google the MTP driver error I was getting on connection and in device manager and found it was due to a registry problem. If you're having that problem I can find the guide again and send it to you.

USB Problem

ok when i plug my player into my laptop, the laptop makes a sound like it knows its plugged in. I have all the drivers installed and never had an issue before but now it shows up in device manager as an unknown device with the yellow triangle. My player won't even show that its connected to a pc and i can't mount it. It also doesn't acknowledge when its plugged into the charger. if I turn it off and plug it in, it just comes on. It used to go to the battery charging screen and i would have to manually turn it on. the fact that my laptop acknowledges that something is plugged in makes me think its not a hardware problem and the fact that i take really good care of it. any ideas??

Wrong section.
is this only your laptop? Does it work on other computers?
sadly i don't have another computer to try it out on. but right when i read this i plugged it in my xbox and it started charging.... and it still won't charge with the wall charger
sorry about the wrong section also
It may sound stupid but turn off your player and turn it on again. This happened to me once and that did the trick

that was my first thought but it didn't help. it won't even mount in recovery mode
ok i just tried it on a friends laptop and it shows up as unknown also
try deleting it from your laptop and let it install again worked for me : )
it always shows up as unknown... just did a full wipe and reflash and nothing has changed

Have you installed Kies. You can use the reinstall the driver option. Another thing is while it is plugged in uninstall the device in the device manager. Then unistall everything under you universall serial bus controller one at a time. Then click on the action command at top of menu bar and scan for new hardware.It will reinstall the usb hubs and root hub. Make sure your player is unplugged when you do this. Then reinstall the samsung usb drivers then plug in after everything is done.

Exact same thing happened to me. Try using a different cable. I used a different cable and it started working normally again. Remember to plug it in and out slowly to avoid damaging it.
One easy thing to check for is whether or not the PC detects the player. Assuming you have Win 7 (the steps for Win XP is nearly identical), right click on My Computer and select "Manage." Go to "Device Manager" and find out whether or not your devices is listed under "Universal Serial Bus controllers"
I had this problem happen to me before and the first step in its solution was going here. (The rest of the info is on multiple threads around here)
ok i tried uninstalling it in device manager and reinstalling the drivers with kies but it still registers as an unknown device. i tried 3 different cables and so far the only way to get it to charge is to plug it into my xbox while the the xbox is off.... i can't get mass storage cuz my player doesn't recognize its connected to a pc... it doesn't acknowledge when i plug it into the wall charger still. the last thing i remember doing before this happened was i installed minfree manager and used some settings i found on the internet somewhere and then i deleted the data to Wild Blood and uninstalled it because i couldn't get it to run without lag

what drivers are installed? it'll tell you when it tries to check for drivers, checking off what you have and what driver-installations failed, if you check for it in the lower right hand corner
ok i charged it to 100 percent with my xbox and now it will at least charge when plugged into my laptop but not mount. it still doesn't charger with the wall charger either. i have no idea how to check what drivers i have installed. i assume they're right because i downloaded the kies from the samsung website as it was the only download option for the yp-g70 ... i've uninstalled the "unknown device" repeatedly with no luck. i even tried to update the drivers and point it to the usb drivers folder in the kies installation folder and it still doesn't work... idk what to do...
At least you can charge mine won't charge using anything I'm down to 15% I don't know what to do, I'm having the same problem as yours ima try using my ps3 to charge

Well, I had the exact problem a few months ago and fixed it. Disclaimer- low-medium risk. no responsibility here
I'll give you the condensed version, since the whole is posted elsewhere. after deleting the existing drivers from the laptop, I plugged in the SGP. in the icon tray, the lower right corner, there's this gray box that appears with circular, moving arrows. Right click to see what's being installed. It's automatically connecting to your USB device and searching for teh drivers. every driver but the Mass Storage driver (I forgot the exact name of the file- MTB comething?) installed properly. from there I went to the device manager and found option under the USB controller in properties to fix the problem. took me a few tries.
i mean delete your usb files on your laptop when you plug it in it will install the usb drivers then it should work again : )
thank you everyone who helped i'll make sure to go thru and click thanx for all of you. especially since this was the wrong place to post this. i finally got it to work. i noticed that my usb cord smelled like my cologne and so i wiped it down with alcohol and a qtip only to see the qtip turn green. from there i knew there was corrosion involved so i followed the instructions in this thread http://forum.xda-developers.com/showpost.php?p=30778095&postcount=1 and now everything is back to normal so again thanks everyone!!

[Q] TF201 not connecting to PC via USB

Hi all,
I am having difficulty getting my TF201 to sync to my Windows PC via USB, and nothing seems to work. I've already tried rebooting both devices, I've made a Factory Reset on my Prime, tried using another PC (and even an Xbox), and I've even tried purchasing another USB cable, but nothing seems to work. Although the cable(s) charge my Prime just fine. I wondered whether it couldn't be a problem with my Prime's connector, but I'm skeptical since the connector can charge, connect to my mobile dock, and recognize peripherals attached to the USB port on the dock.
When I connect the Prime to my PC via USB, the Prime doesn't show the USB Debugging icon nor the ASUS Sync icon, while the computer also shows no signs of recognition that the tablet is connected, not even on device manager. ASUS support (very crappy, btw) told me to install ASUS Sync on my PC, but no luck. However, my Prime's screen does turn on when I connect it to the PC, which, I believe, indicates that it is doing that painfully slow USB charge, but that's pretty much it.
I normally wouldn't mind, but I want to get root access for my Transformer Prime (running 10.4.2.17 JB firmware), and using ADB/Fastboot seems to be the only way. Is there any other alternative way of rooting the Prime? or is there a way to using ADB/Fastboot wirelessly, without root access?
Any help is really appreciated (this has been annoying me for a few months now).

Ah, I miss the days when the TF Prime could be rooted straight from an apk, without having to use ADB. Ah well, guess I'm not getting Android 4.2 then
