My problem is almost the same. But, I can't connect my mini USB HDD 2.2Gb (Like a memorykey). When I plug it, the system detects something in USB, but do not assign a drive letter, so I cannot access the files.
This happen after I install DT 4
I already disabled all virtual drivers and uninstalled DT 4, and problem doenst disapear.
My others USB devices is working perfectly (joystick, mouse, webcam)
Anyone can help me?
