Greetings!
So, recently, my Transformer Prime stopped being able to connect to my PC. When plugged in, the Prime does show that it is receiving current on the cable, as the charging symbol shows up, but that is all. Windows shows no indication that the Prime is plugged in. This includes looking in Disk Management and in Device Manager. Nothing. Oh, and USB debugging on the Prime is turned on.
I have tried two different cables (both of which will definitely charge the unit), and 3 different PCs, all with no change. Additionally, there is no visible damage at all to the port.
I even ROM'ed it (after the problem started) with Cyanogen10 and nothing changed. Finally, I tried it with the dock, and while the dock works fine when they are coupled, if I plug the dock into a PC, still nothing.
I am sort of out of ideas. Anyone else have any?
Thanks!

There is another thread with a discussion on this. Perhaps it will help. Read through the posts to see any trouble shooting suggested, but I'm guessing your USB port is dead and will need to send the tablet back RMA to get it fixed - sorry to say.
See the thread here: http://forum.xda-developers.com/showthread.php?t=1624175
I had the same issue, and unfortunately soft bricked my prime while trying to see if different ROM's would fix the issue. the soft brick would have been recoverable if my prime would connect to my PC, but it didn't so I ended up paying Asus to repair the unit.
If none of the troubleshooting works, I'd flash back to a stock ROM and then send it in. mine would only boot into CWM so once they saw that, they figured that was the problem and charged me for the repair. I had seen a couple of people say that even though they were unlocked, the prime was fixed for free since they were able to boot up into the rom.

Can I ask how much they charged you to fix it? I'm about to send mine in for RMA, but have a cracked screen from a drop. USB worked for weeks after the screen crack, but I'm concerned they will say it broke due to my neglect. (Basically I don't want to spend too much to fix it with a broken screen). If I can get the USB working again, I'll consider spending some cash to fix the screen - but to pay for both I'd be better to just but a new tablet.
Never mind, I see you already answered me on a different post. $232.

Woot gTabber here. No problems with my device; rooted, running Vegan 5.1.1, and working like a charm...until now.
I've noticed a problem when connecting the charger. When plugging it in, the gTab won't charge. The indicator light does not come on, although the green light on the charger is on. I wiggled and adjusted the jack until it connected and that worked for a few days. Now all the wiggling in the world won't make it connect. I tested my tab with a friend's charger and it didn't work either. It seems like there is a problem with the port and not the charger.
So. What are my options here? Is this something that can be repaired?
If it was a recent purchase, see if you can get it RMA'd for a replacement unit.
I had the same thing happen to my G Tab. Received an RMA and sent to Support. Received a call from Viewsonic that it was abused!! Haven't dropped, bumped or anything else. Using it with it plugged in is just begging for that dude to break inside.
I'll advise on what Support ultimately does if anything.
Edit 6/17/11: Received unit back from support. They repaired the port under warranty after about three calls accusing me of abuse. After the repir it seems to sit in tighter than before. You should be warned that support put the 4349 ROM and 1.2 bootloader on the device and cleared everything including the sdcard. I had to nvflash back to 3588 to get it reloaded with VegaN Ginger Edition and the 1.1 bootloader.
My 2nd Gtab is the 1.2 with 4349, I have had it about 3 weeks DO NOT like stock rom so I flashed it to flashback, then went to charge it as I ran the battery down, and I have the same problem! No light, no charge, sounds like it will be a fight with Viewsonic repair. It appears that the port has been pushed in. Has anyone out there tried to do their own repair? I have to flash it back to stock if I want them to repair it, can't do that unless I can charge it. Had software problems on my 1.1 and it took forever to get it back. I would rather try the fix on my own or pay for a fix in town.
Other than that I love both my Gtabs, the Flashback rom looks good but I have not had a lot of time to play
Once again thank you to all, any and all responses are welcomed

If you're down to do a bit of soldering, pop the tablet open and make sure the power connections are properly tacked on.
tried no luck
just sent back to woot for refund
it appears that it ad been opened before suspecting they sent a refurbished. The power port was totally off the board pads. Tried to resoder must not have been a good connection. It sounds as if GTAB has a problem with this, or is it just our 2?
Think of another tablet any suggestions being as woot id giving me a refund
Let me know thx Jaye
I had the exact same issue and instead of trying to repair the plugin I ordered a dock which charges the G-tab through the HDMI port. Kills several birds with one stone.
The same problem with me. CosmicVagabond, thanks for the good idea, will do it.
Can you give me the link you bought it from? By how much did you buy it?
I have that issue as well. But wiggling the cable until I get a light generally works. I even bought another charger for it and it does the exact same thing so it's the port on the tablet and not the charger. But hey what's a little wiggling to get what you want?! And no, I've never dropped this tablet.
Hey guys, thanks for dropping by.
I have a very wierd problem, that I just cant figure out.
It all started the other day, when I found my tablet dead after having been left on and charging during the night. The tab was dead, and I feared the worst. After having left it on what seems to me like a trickle charge for several hours, I managed to get it up and running, and the tab seems fine, it was just completely out of juice.
But my troubles are not over. Whenever I'd connect the tab to the wall charger, I'd only get the red "X" symbol in the corner, and it would say MTP Initialize, even though its plugged into the standard OEM wall charger that comes with.
When I connect the tablet to my computer using the same cable, nothing happens, and by that I mean nothing. Computer doesn't start the connection process at all, its not recognized in the device manager, nothing. Not even Odin can see the tablet when I put it in download mode, the tab keeps saying "Waitting USB Cable..."
Tried this on 2 computers, still no luck, even using a USB plug on the motherboard instead of front-usb.
Now, the tablet will "trickle charge" from both the wall charger, and the computer, but nothing else happens.
I figured it could've been the ROM, so I got the latest ICS Kanang ROM downloaded, transferred it to my tab using Bluetooth, and flashed this without hassle, but the problem still persists, only now showing a regular charge icon in the lower right section, but it is still only trickle charging as far as I can tell.
All I can figure is a defective USB cable, or even worse, defective port on the tablet itself, but I'm not sure. I've ordered a new cable from DealExtreme, that will hopefully arrive sooner rather than later.
But seeing as the tab is hardly 4-5 weeks old, I find it difficult to believe the cable is the problem.
Anyone have any ideas? I'm all out at this point, so any pointers is very appreciated. Thanks.
It could be the cable. It's the part you have used in each situation. I'd wait for the cable to arrive and test it with the tablet when you get it.
Sent from my GT-P7510 using xda premium
Hey, thanks for the reply.
Yeah, I really really hope this is the case, time will tell, DealExtreme is not the quickest dealer. I'll update when I get it.
The new cable came from DX, but I'm afraid it showed no difference on anything.
The cable is working just as the original one, so that's not the problem.
Anyone have any ideas?
I guess my main goal at the moment is flashing it back to stock and un-rooting so I can get it repaired.
You mind posting a screenshot, it's kinda hard to imagine what you see by what you read For all I know my imagination went from a red X to the corner to something like an X off battousai's face.
Then again, I'd be glad to help, provided you post screenies, would be a major help
Ah, yes, I will take screenshots of anything you want to see.
Right now im on ICS preview, and these are some snapshots WITH the cable connected.
The red "X" I'm talking about you can see on the first picture on the charging icon, this happened even when the wall charger was connected on gingerbread/overcome experience rom.
The other pictures you can see it says discharging. Now, this was taken when connected to the computer, and I guess that's normal, but it also happens exactly the same when connected to the wall charger that came with the unit.
If you want screenshots of anything else, ill get it asap!
I took a poorly image of the tab connected via USB, to my computer with Odin open, hopefully you can see what it says.
If not its just what happens, I don't get further.
By the screenshots, Is the language Swedish?
Then again thanks for providing the screenies
In your first screenshot that could be part of the theme, or was it never there previously? I don't really know if it's not charging or that's supposed to be the charging icon, because for some odd reason on ICS preview I don't see that red icon anywhere.
As for the tablet, the reason why you aren't detecting it seems as though you don't have the drivers on the PC, I don't know if you installed them or you didn't mention it because I never found it being mentioned in your reply. I know it sounds silly but the same thing happened to me when I was using the tablet, (originally my 3G series belonged to my dad who knew nothing about modding so he just gave it to me and said, "do your thing" ) He did also forget to mention that you require to have the drivers to detect it via Device Manager and MTP in general, shortly the COM port will show up aswell. Perhaps re-installing the drivers should do the trick?
Made me wonder how did you install ICS in the first place if you weren't able to have it read? But I realized you could have downloaded the zip file via the tablet, On another note, how did you install CWM in the first place? o.o
Hehe, almost! Its in Norwegian on the honeycomb picture.
The red "X" would show up whenever i was connected to the PC via USB, to indicate its not charging. It will however "trickle" charge, and take 24h to charge fully with no usage and turned off.
Yes, the red icon is not on ICS, it just says not charging in the about page, as you can see from the screenshot.
Drivers have been reinstalled two or three times on two different PC's, I don't believe this is the issue.
When I bought the unit, it was working 100%
USB was okay, I flashed and rooted the unit over to "Overcome Experience".
From there I transferred ICS preview via Bluetooth and installed that way.
Have you tried factory reset to make sure all modules are reset? Maybe the USB charge module in Overcome is conflicting.
Yes.
Factory reset 3-4 times on the two different roms. I've reset everything I could find, without success.
Perhaps it has gone faulty with the tablet's plug in port, someone had the same issue although it was his wire that was at fault, it detects the charge via USB but not enough volt's to be detected by the PC, has it been grounded? Seem's more likely :| Might have to get it checked in your local center perhaps, It's how I mentioned that any metallic object is able to relay electricity despite being broken or not, you may have a broken pin for all I know :|
Hi,
I'm having exactly the same issue with my 1 month old tab 7+. I tested it using my bosses charge cable and there is no issue so I need to go to the service centre for a warranty replacement on the cable.
Hope you sort out your issue soon!
Thanks, but I don't think I have any other choice to deliver it to Samsung Europe as a payable service to get it fixed.
Purchased on a American store, and I doubt they'll take it back with flashed software.
I'm not sure really, I'll see what I end up doing. Its not the cable, that's for sure.
I don't know if anybody else has had this problem before, but I hope there is somebody out there who can help me with my problem.
Basically, until a few days ago, my Galaxy Tab 10.1 was working fine until I did a reinstall from a backup as I was having a problem with the device due to it running sluggishly slow and crashing every so often.
Now, for some weird reason, the device won't charge at all when the USB cable is plugged into the official USB AC Adaptor and instead all I get is the "MTP Initialization" message that somebody would usually get when connecting the Tab 10.1 to a PC or Laptop.
It seems to charge when hooked up to a laptop very slowly but that's about it.
If there's anybody out there who can help me fix this problem, it would be most appreciated at all (to be honest, I can't wait until I go back to university in September and I can sell this POS and buy a 64GB Transformer Pad Infinity instead!)
EDIT: I've tried another cable and now it's saying that it's MTP-Connected instead of not MTP-Connecting at all!
Bump as I have a feeling that this isn't a one-off problem and that it's affecting a lot of other Tab 10.1's as well...
Never had that issue.
Are you sure your cable is ok?
Having exactly the same problem, no idea how to fix it at all. Looks like it's faulty usb port, because sometimes my laptop 'recognize' the tablet, but it's very rare (don't really know what does it depend on). I'm afraid sending the tablet to service is the only solution .
Try a different charger, different cable and check the port for debris
Sent from my GT-P7500 using xda app-developers app
I've checked the port and there's no debris in it, I've checked the new cable that I've bought and it's already worn through from the look of things at the end with the plug that connects to the device itself.
Guys, I'm convinced the usb connector on my 9 month old TP is defective and gets worse each time I use it. I had bought a touchstone charger to ease the connector wear but still, I was eventually having problems with USB data connectivity using store bought cables. I even sent my TP in to fix the connector and when I got it back, still no USB connectivity. Just a completely wiped TP. So HP sent me one of their "genuine" silver dot cables and low and behold it worked fine. (My original cable was lost)
Now, months later, I'm having problems with the USB data connection again. I either get the "Not enough current message" in WebOS or no MTP USB symbol in CM9. Sometimes the PC will chime positively but with an error message (can't detect device). I received another genuine HP cable and it behaves the same as the other one. Inserting them normally, they appear to be in tight, the PC will chime but Windows will say that there's a problem, can't detect device. The only way to get it to work is to insert the microusb side at a 45 degree angle tilted downward and hold it in for 5 seconds, then (ever so slowly) release the pressure to the connector. 50% of the time I'll get a Windows message that says the USB is degraded and run slower than normal (which I think means it thinks its in USB1.1 slow xfer mode) and 50% it works fine at USB 2.0 (until I pull the cable out of the connector). I also have 2 store bought cables that won't ever successfully connect to USB with the TP but work fine with my Samsung cell in both charging and xferring music over to the phone.
So what I'm getting at here is that no standard microusb cable is the same and that there must be something special about the HP genuine one. Do these cables have a resistor on pin 4 ID tied to GND pin 5? Even so, I think what is wearing the most is pins 1 & 2 and maybe 3 (VCC and the data pins) which is why it may only work by concentrating on seating those pins first. Does it make sense that the 'can't detect device' message comes up with just the data lines and ground connected but no VCC? For that matter, why would the battery symbol in CM9 always show the lightning bolt assuming pin 1 VCC is not connected?
I'd appreciate any responses from other members here since I believe without USB the TP could be bricked in case some boot code gets corrupt and you are forced into WebOS recovery mode. This has never happened to me yet and I've installed a lot of nightlies but it COULD happen, no guarantees. What is inevitable is my connector will eventually wear out and my TP will only live until the bootloader DOES get corrupt, hopefully later than sooner. This could be the case with all TP's. Just imagine if in a couple of years everyone's TP's USB port goes bad. Sounds like the devs should figure out a way to fix a bricked TP wirelessly, if that's at all possible.
Thanks,

One of my Touchpad's had the same problem in Webos it said using wrong charger may not charge or something similar and with Android ie nightly the charging signal came up but it did not charge.
I spoke to HP and pointed out that I have 2 Tablets and that swapping leads or chargers made no difference all combinations worked on one but not the other.
They agreed to fix it and replaced the part. It is now working fine. And as with yours my computer failed to recognize the tablet properly.19 times out of 20 on the one time it did I was able to back up and remove Android before HP picked it up.
I would send it back under warranty or if that has expired state that it was preexisting. Otherwise as you said it is going to become pretty much unusable.
Don't let them fob you off.
Good luck

once u get an RMA they will send a box and take care of Shipping.
then go here to wipe and remove android

Thanx for your prompt responses. I bought my TP at the 2nd fire sale through BB in early Nov so I still got a few more months but I would rather wait a bit more since they did nothing the 1st time around. I think the connector is on some daughter board along with the vibrate device which is soldered to the main board. Doesn't sound like a big deal to repair it. Still, what makes the HP cable different then the others? Are there known cables I can get online that might be made better to always work and make better contact than the HP ones?

i keep track of the serials and they always came back the same. i have more than one pad and i asked for one to be replaced completely. we will see if that happens. but they fix only what u ask for and nothing else.
it can take longer depending on Weekends. takes 2 days to get your box, then 2 days to get it to HP, then 3- 4 days to get your fixed unit. its all done thru UPS, cant send it out on the weekends or receive it

Hi all. I know this thread is really old, but I'm finding myself dealing with similar issues. And I'm obviously out of warranty. I can't get windows, linux, or Toolbox to pick up the USB. I'm actually in a worse case scenario mention here and am stuck in meboot, TWRP, and WebOS recovery, because I had wiped the rom. It must be an issue with the USB port, I've lost track of my original Hp touchpad OEM cable, and have tried every USB cable I can find. Any help would be appreciated.
Earlier today I wanted to move some files about on my phone in preparation for a wipe and reflash. I managed to copy off a backup I made. Suddenly, the USB disconnects. Thought the cable may have simply disconnected, I proceeded to unplug and replug my phone, but no dice. The phone seems to charge, but USB connection does not initiate.
I tried rebooting both machines and reinstall USB drivers, but still no connection.
I ended up giving up for a bit and played a game for a couple of hours. Weirdly, during this time my phone happily connected, providing the USB options in the notification area.
I ended up unplugging my phone again, but when I plugged it back in a few moments later, it did not connect. It's since been connected for around 15 minutes, with absolutely nothing but charging occuring from my phone.
Any help would be a appreciated.
Thanks!
Edit: I have also tried numerous cables.
I've also encountered this problem, look for something called 'MTP fix' and see if that works!
Sent from my GT-I9100 using xda premium
USB port/board on the fritz. Replace before it dies completely (you won't be able to charge/etc). You need to work out which revision of the board you currently have in the phone & buy the same board (cheap; eBay/etc) & swap them out.
Search for similar threads, there's been a lot of discussion here about this issue/which board you need how to replace over the past few mths (including photos).
Aw crap.
I'll try the MTP Fix suggested above, but if that doesn't work I'll look into this. How difficult is replacing the board?
