I have an asus p6t se.
i have installed a 4 port hub in one of the drive bays that connects to a usb port at the rear.When it is connected the hard drive light comes on when the pc is turned off and occasionally the pc wont power on until I turn it off from the wall for a minute.
Anybody help? Thanks
Yes and No, you MUST use the 4-pin Molex that's part of the kit and connect it to your PSU. If the problem continues then open the Device Manager, open the [+] Universal Serial Bus... then right-click Update Driver for ALL items listed. Better use a PS/2 Keyboard, requires restart, and Delete ALL items listed. In either case followed by a restart.
Connecting an underpowered 4-port HUB + Device(s) can equally damage your MOBO's USB and overload it.
Question, if you disconnect the HUB and connect to 'another' device to the SAME USB port does the problem "when the pc is turned off and occasionally the pc wont power on until I turn it off from the wall for a minute" persist or does it go away? If this corrects the problem then it's clear the HUB is the problem.
If it were me, I would get something else. Your best bet is to use the internal USB header(s), PCI USB, or external powered USB HUB.
