I just bought a hdd enclosure which uses usb2.0. But it works on usb 1.1 too. But i have a problem is that when i switch on the hdd enclosure. The computer recognise that something is plug into the usb port and it start to install the hardware. Sometimes, it installed succussful, sometimes it doesn't. Most of the times when i go to the device manager, there is a exclamation mark beside the usb hardware section. Sometimes when it install succcessfully, there are no exclamation mark but the drive does not appear in the my computer there at all. I am sure that the enclosure is alrite because i tested it on other computers. Does anyone have a solution for it?
