Hi there
Here's (I hope) a quick solution to your problem.
First of all, make sure that your motherboard supports usb2.0
otherwise this help will not work.
When re-installing my usb 2.0 driver after a system crashdown I
received Error -536870389. This means that he did not find any EHCI
controller installed, that is, the Hardware was missing (!)
Going to the Bios and loading the defaults solved the problem.
If you have a newer Bios version than you can also check in detail
whether a USB Host controller is enabled or disabled.
If you have an older version, try to update your BIOS and enable the
USB Host Controllers.
>> Stay informed about: USB 2.0 ? for older mobo
