My computers have quit recognizing my blackberry when it is hooked up to them. The blackberry software says that there isn't any phones hooked up. When I hook my phone up to a USB port it use to charge now the charge indicator comes on but in just a few seconds it shuts off and doesn't charge. The phone will still charge when plugged into the ac or dc charger. Also about the time the problem started I got a new symbol at the top of the screen that says H-T any help?
You also might want to open device manager on the PC and check USB root hub to make sure that "allow computer to turn off device to save power" is not checked.
