sounds like your usb port in your computer is bad.

 

Mine is doing the same thing and started about the same time. Except mine does it about 98% of the time. I'm out of town for work, and where I'm at there is no internet service, so I've been using the Evo to tether my laptop to the web via usb using the paid version of the klink app. It was working great, until about 5 days ago. I went to plug the phone into the computer, and as soon as the usb cable's male connector made contact with the laptops female usb port, the computer died. Not shut down, shut off. I restarted the computer multiple times, and each time I went to plug the phone into the computer, the computer shut off. I don't understand whats going on. Nothing has changed with my setup. I always have windows update OFF. I haven't updated the phone. I've been researching this online and was hoping that it was just a faulty usb cable, but I've bought and tried a new usb cable, and the computer still dies..... I cleaned the usb port on the phone with an alcohol wipe, then made the connection and it worked for about 45mins. Then the computer just shut off... Any help would be greatly appreciated. Oh yeah, I'm running windows vista 32bit. Sorry so long, just trying to be thorough. Thanks.

 

welcome to the forums!!!!!!!!!

sorry to here that you are having issues with your usb cable. you might want to try and plug in other devices via usb to your computer and see if the same thing happens.

 

Thanks for the welcome Ocnbrze!
But yeah, I've tried other usb devices and everything works as it should. I've come to the conclusion, that the usb port on the phone itself is faulty....
