For some reason my Epic 4G doesn't prompt to mount as USB Mass Storage device or anything for that matter like it used to. Now when I plug it into the usb port on any computer it just starts to charge. USB debugging is disabled. Is there anything I can do to get the prompting option back?
Probably a dumb question here but did you try different usb ports or a different cable?

Yeah, I've tried different cables, and different computers as well.
Had the same problem, I was using an Micro USB Cable from an LG phone and it wasn't prompting for mount, used the samsung one that came with the phone, came right up.
Not sure if it helps but just try the one that came with the phone.
I've also had this same issue. I think this is what it is.
I too used a cable from an LG Phone and it did this as well. Turns out the cable was a charging only cable, couldn't do data. This could be what you're running into.

Well, just grabbed the cable that came with the Epic, and it worked! I could have sworn I tried it, but maybe not. I have so many micro usb cables laying around, I guess I better make sure I don't lose this one.

That makes alotta sense. I was using my cousing EnV touch cable and it wasn't giving me the option. I'm glad I have a clue now!

I think the biggest advantage of using a cable that doesn't do data is that they normally give more power to your phone since it doesn't have to do the extra work of transferring data.

Yeah, I was reading somewhere about some pins being shorted on charging only cables that allows the phone to draw 600mA from USB just like it does from the wall. The phone can tell the difference and will only prompt when it receives the trickle charge of ~380mA which you get from a non-"shorted" data cable.

just noticed this morning when I plugged my USB cord in. anybody else have this problem?
oh, i have already tried different usb cables as well. it's rooted, so im pretty much screwed.
A bit more description might yield better results. How long have you had the problem? Does it work when plugged into a computer vs. wall?
I've randomly had times that my phone wouldnt "recognize" that it was plugged in to a wall charger, but that lasted for no more than 5 minutes.

Other people have had luck getting htc to repair/replace damaged handsets even after unlocking the bootloader. I would try that, what the worst that can happen, they say no lol. I wouldn't volunteer that you unlocked the bootloader, but it shouldn't really matter, since that has nothing to do with a damaged usb port.
My Vibrant's touchscreen gets screwy when connected to any of my laptop's USB ports, when the lappy is either on battery or wall power.
By screwy I mean it misreads my presses, as if I pressed elsewhere on the screen. I'm in the 30 day swap period still, but I was lucky enough to get a very bright screened model and am reluctant to swap it unless this power/screen problem is to be worried about.
Have not been able to test on another computer's USB ports yet.
Thanks.
edit: Dell laptop.
Mine works fine OP when connected to both my laptop and my desktop.
Does your laptop happen to be a macbook? Because this phone has problems with apple computers.
No, a Dell. More specifically, this is not when mounting or using ADB. This occurs when merely connected and charging. Seems like it's a spurious signal coming down the USB line from the laptop is my guess.
I've had that unfortunate experience since day one of purchase. I went through three Vibrants.
I swapped the first one because of the touch screen bug with the USB connection. Also, the back button would periodically "stick" and continuously press back until I were to tap it again.
When I got the second one, I realized the issue with the USB remained the same and the "sticky" back button was more frequent than the first one.
The third one that I have now has a more responsive touch screen with the USB connected. It would act up 50% less than the first two. It has moments when it works just fine when I move the cable around and make sure I'm not touching the cable there on after.
My coworker doesn't experience that problem when he tries it on the work computers and my phone doesn't have that problem either. It only acts that way when I plug it into my x64 Sony VAIO, so I'm wondering if it's some sort of related issue.
Don't feel bad. I've been searching online for some sort of remedy since its release and have found nothing.
Are you using the USB cable that came with the phone?

I've always used the cable it came with. From reading your post, I just tried a USB with a micro USB converter tip, but it still produces the same symptoms.
I had the same problem. went to T-Mobile store (thinking I needed to get a new phone) and after a couple of tests, they gave me a new charger... that solved the issue 100%, so in my case, this was the cable/wall charger, not the phone
^ that's what I was getting at.

try changing the charger/USB at the store for an original one (not generic micro USB) that took care of me

I swapped al of the contents every time I made the exchange. When it's plugged into an outlet with the charger/USB it comes with, it works just fine. Works fine with any x86 computers at my job. It goes crazy on my x64 desktop and laptop. It's pretty annoying when I'm working on it with Eclipse and I get text messages. It becomes a task just to swype in one word, or disconnect it as an alternative and wait for about five seconds for it to function properly again.
well that sucks. I have x86 at work and 64 bit at home. after swaping the charger/cable, like I said, no more problems anywhere
Wow, I never expected so many responses with the same problems. Thanks guys.
I'm using x64 Win7, so that could be it. Also, am using the stock cable, I have no other micro cables at this time. More in the mail already. I'll check on my bro's 32 bit Win7 laptop and with the aftermarket cables.
Thanks for the responses.

Any update?
laptop issues
I have a HP laptop and if my vibrant is connected via stock usb cord my laptop will not boot. It doesn't get past the first HP screen and it shuts off abruptly and tries to reboot. When unplugged everything is fine as long as it is up and running. I can connect my phone and do whatever needs to be done as long as my laptop has booted up. I thought it was kinda weird. I only plug my vibrant in my laptop while tethering to charge. Anyone experience this? btw running win7 64

It is because the laptop is trying to boot from one of the removable devices that show up whenever the phone is connected.

Sounds like a CPU preemptive latency problem. The USB port may use big time slices of the CPU during the same time the touchscreen positions are being calculated. This should be fixed with the new update.

Mine did the same thing, except it did not matter what power source. When it was plugged into anything, my screen was screwy. Unplug it, and everything worked again. I exchanged mine, and have not had the problem since.
Mine is that way as well, but not with the computer, its that way with one charger that I previously had with my aria. After I unplug, its fine. I read somewhere that the length of the cord might have something to do with it.

I used to have this problem with just one miniusb charger for my G1. The problem is there's too much current. You probably have a USB port that puts out more power on AC and it's simply too much for your phone. If it's getting REALLY hot, that's a sure sign.
Hello community,
trying for half an hour to connect my note 3 to the pc using the OEM usb cable, I kept getting error 43 "Unknown Device" stuff but the phone was being charged. After that, I plugged it in my usb 3.0 external drive cable and got recognised instantly. What do you think is the problem here? I did happen to land the phone-edge of it in a yogurt bowl last week but, after cleaning it, it has been working normally this much time!
(Hope) someone else had a similar experience and worked it out...
Thanks,
jim
Original cable that came with my Note 3 has broken wire inside from new, I need to move it around few times just to get it connect inside and charge phone, Note 3 itself works fine with usb2 cables, or usb3 cable from my back up HDD, so I strongly suspect one of the wires inside your cable broke or has poor connection as well, but here it's data line, not power like in mine. Solution is very simple, use another usb3 cable, that should give you fast charge, or even usb 2, but here probably charge will be slower. You can find inexpensive cables online, also I don't think cables have full 1 yr warranty, like phones do but you may as well try warranty claim. BTW there is nothing special about Samsung charging cable as far as I know and at least in my case any USB3 cable will charge my phone at full speed, just like original cable as long as charger is original.

yes, Kies 3 has been installed since the beginning with the drivers. And as long as the phone is recognised through another cable, the drivers are definitly installed! Thanks again!

As long as I have the backup cable, I just leave the OEM in the wall charger and everything is fine. There is the fact that my Knox is 0x1, but I can just try the warranty with the cable and the receipt :angel:
Thanks again!
Hi, I've been reading but not posting for awhile.. I'm having a issue with my 6P, its not connecting to any computer anymore Mac or PC. It doesn't show up at all, nothing in the status bar to select from, I can see the charging icon show up but no way for me to access the phone to back it up, even in download mode or recovery the phone won't show up on any computer for me to back it up..
Swapped cables to connect to the computer? Changed USB ports? Removed drivers and rebooted?
Most definitely sounds like driver issue. If it was the cable, then I think it would not even charge.
Download the driver right here
Follow install instructions right here.
If you still have issues right click on the device in device manager, then uninstall the driver. Then follow the install instructions again.

Not necessarily true. Some cables only support charging. If you cut it (not that you would) it would only have the smaller red and black cables inside. You need the cable with red, black, green & blue or yellow. I forget. Think yellow. If OP is using a 3rd party cable that may be the case. Also, damaged cable may be the issue. Actually happened to me. My normal longer cable that came with the 6P got a little snipped on the outside and now it only works for charging. When I plug it in it says there was an error installing the driver, which are already correctly installed. I need to use that little mini cable now.
Probably is a driver issue, though.
Hmmm I can't see it being driver issue on both Mac and PC, on the Mac all I need is the app, I know it works because I tried it with a different phone, no driver involved with the mac.. Its not the cable because it charges and I've tried different cables before posting..

Hey thanks man!! I was not aware of that. I knew about USB Type C cables not meeting certain charging standards but was not aware some of the cables might be missing the data transfer wire inside the cable. I guess it is also possible the data wire could be the only 1 to break or fray, but chances of only that wire breaking are probably pretty slim.
It is kind of surprising that Nexus drivers are not automatically recognized and downloaded by now. Especially in Windows computers. Weird we still have to keep manually downloading and installing it when most other devices have their driver automatically installed when plugging it in.

I'm not using a 3rd party cable, I've been thru that, cable quality is not issue, I've used the cable that came with phone and new one a friend got with her phone two weeks ago. Like I said Mac does not need drivers just the app and thats it not only that if another works on my computer what does drivers have to do with it?
Hello all, when I try to plug in my phone to my PC, the phone says charging slowly and no USB options pop up. Fast charging is also not working, and I get the same message. I bought a new charger from walmart because my original one broke. Thanks!

Or a bad cable. There's a lot of those going around these days.
When your charger "broke", did it short/burn up? If so, it may have damaged the port on your phone

No I believe 2 wires broke on the inside.
+1 for bad cable.
I've seen it many times. Fortunately, I have about 2 dozen USBc cables laying everywhere.
I try to get the offending cable in the garbage, else it gets back "in service" and creates frustration again...
I beleive the issue is with the cable. Try with another new cable and tell us the result friend.
I kept all my good micro USB cables and simply bought C adapters from Amazon.
