Comment 16 for bug 1332722

I have tried different cables. No good. Maybe all of my usb cables are poor quality? I tried a different usb hd external enclosure but same results. This time I caught all of the dmesg errors as they occurred. BTW: I disabled all usb 3.0 support in the BIOS. This means Mint is handling everything and the BIOS is not handling anything. Most of the BIOS settings are for when you have an OS that cannot handle usb 3.0 properly and you need the BIOS to handle it instead. I am going to try this all out in Windows 7 as my next test.

Here they are:

Unplug usb cable while drive is mounted:
