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

Happens on my HP aswell but with a Droid incredible connected, must be a HP issue

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.
Anyone else notice that it won't charge from a computer? (well monitor) With my Aria i ran a USB cable from my monitor at work to the phone. the monitor wasn't connected (USB) to the computer, and it would just work as a charger. Doesn't seem to work with the atrix. anyone else able to confirm?
more info. does in fact charge when connected to a computer. but due to security reasons the company does not want phones connected to the companies. That is why i was using the monitor. Going to have to look into why it doesn't work this way for this phone. or just buy a longer cable and use the wall plug.
Mines actually not charging when connected to my laptop, wall is fine. The phone recognizes that it has a usb connected, but it doesn't charge and battery state still reads as discharging.
Also wondering if this is an issue for anyone else
Mine charged extremely slow from my PC and my laptop, the wall charger does it much faster.
USB ports on a computer don't usually provide enough voltage to charge a phone as fast as they normally do when plugged into the wall. My motherboard actually has a piece of software that supposedly enables phones to charge faster when connected to a USB port, but i have yet to try such a feature.
I've had my Atrix plugged into my computer for roughly 3 hours now, and so far it's gone from 30% to 60%.
I wouldn't be the least bit concerned if it was charging slowly, it was actually lower after unplugging than it was when I plugged in, and no charge symbols appeared. But if I plugged it in the computer saw it and soon as I unplugged the message popped up saying low battery please reconnect charger, and when reconnected it went away.
But there was no charge symbol and under battery status it said discharging.
Now I just unplugged from wall charger (worked fine first time) and plugged back into laptop, its charging fine so hopefully it was a one time thing.
Ah, so thata what it is; I have had mine on here for a while now and im still at 60.
Rooted/ROM Captivate
Rooted Atrix
When i first plugged mine into my desktop computer, it wouldn't charge at all. I then installed that motosoftware that came with the phone and after it finished the phone started to charge, but very very slowly.
Every computer ive tried works fine.
But when i plug it into a wall charger(not one that came with atrix) it starts freaking out lol. "unplug to save energy!!" flash on & off 3/second...atrix charger works fine tho...lame
You need the driver off the motorola site to charge the phone from your computer.
Yea, computers work, monitors don't. I'm guessing that the USB hubs in monitors don't have enough juice, even though they did for my Aria.
I've had my Galaxy S2 for 4 months now and now have a problem. When I plug the phone in, whether to USB or to the charger, it takes it a bit to recognize the phone is plugged in and to start charging. When I plug it in to USB it will charge after a minute, but I can not connect my phone to be mass storage. Windows can't detect it at all. If I disconnect the usb cable, my phone still thinks it is connected, with the notification for USB connection staying in the notification bar. In addition to this, my phone gets excessively hot regularly. I always make sure there isn't a runaway app, but that doesn't seem to matter.
Any one have any ideas?
I found a thread that describes my problem here.
http://forum.xda-developers.com/showthread.php?t=1216163
I think I have solved the problem. I somehow managed to bend the USB pcb connector. I bent it back up towards the screen and everything is acting normal again. Read the link above for more information
Has anyone tried using a light for the nook that is powered by the micro USB port?
I haven't found any USB lights with micro USB connectors, but was tempted to buy a laptop USB light and swapping the connector for a micro USB connector.
Plug it into your nook touch and you have light. Of course this will drain your nooks battery faster, but I would hate to have to worry about charging batteries on a reading light in addition to ensuring my nook is charged.
It may be possible, just check if the power drain is not very high, as the USB has a limit of 500 mA (if I am not mistaken). If it works, please tell us.
You will need the USB hack that is on the forum, but I guess there is nothing that would prevent it to work (just maybe frying your USB connection).
Good luck.
You should be able to draw some decent current off the USB connector.
I've pulled >100mA trying to power a hub.
I don't know how much current those LEDs pull but certainly less than that.
It's unfortunate that 2.1 doesn't support reverse portrait or you could have the light at the top!
Light working
Hi. I saw this thread and then I've remembered that I should have an old laptop light so I gave it a go

Nice....I just ordered a plug on amazon at the moment to do basically the same thing. I've got an old light at home that still works.
Plug: http://amzn.com/B005FUNYSA
Have you used it any with the light? How does the battery handle it?
I'm tempted to sell my current Nook Touch and get the one just announced: Nook Simple Touch with Glowlight, IF the Nook powered light isn't great.
Edit: I received the plug, however the light i have doesn't seem to light up off of it. I checked to see that it works off of a USB port on my computer, so I'm not sure if it just wants too much juice or what. I wonder if I need to be rooted, to allow it to work (doubtful, but not sure)...
I'm looking to see if this is normal behavior, bad cables, or a bad phone. When using aftermarket charging cables (c to c or c to a) the charging speed fluctuates from down to 40mA all the way up to 3300mA. Its less pronounced with the OEM charging cable.
What got me thinking this was an issue is I cant get data to transfer from my 6P to my PC without getting errors. So far I've been thinking its my PC problem and I dont really give a hoot but now Im starting to wonder if its an issue with the port.
Using some Amazon cables the phone will mount and dismount constantly. Using the OEM "developer" cable that came with the phone I dont have that issue but I cant move anything over USB to my PC. I get constant transfer errors.
Do I get a replacement or is the charging issue at least normal? I dont seem to have issues charging as I wake up to a fully charged phone every morning (and hot damn my phone lasts a day and a half of moderate usage.)
bad cable most likely, i bought a usb c (C-to-A) from aliexpress that was non usb c standard compliant. charging was slow but i didn't noticed any worrying fluctuations. data transfer from is always disconnection and reconnecting every half a second, although when flashing in fastboot showed no problems. as long as it's not the usb c to a cable that fluctuates to 3300 mAh and you're only gonna use the cable for charging, it should be okay to use it for a while, although i would recommend getting a usb c standard compliant cable at your earliest convenience.
I got my new cable (usb c to a) from ebay made by baseus and best third party cable i've used so far
