I'm having trouble with my usb hard drive with usb2.

It give read/write (at least I think it is mentions blocks etc., I can't read the language to confirm.)

As soon as I plug it in it generates errors and kills massstorage.device.

I have tried 2 cards, an nec and via. The Nec doesn't work and the via works with mice and thumb drives.

Interestingly if I try to go to system setting the system locks up.

Lastly the mb usb won't work when the via is plugged in.
