Scanner Epson Perfection 1670 do not support USB_SUSPEND

[Oleksij Rempel]

Binary package hint: linux-image-2.6.20-13-lowlatency

This scanner seems to support powermanagment but will breacke with USB_SUSPEND.
All USB_SUSPEND enabled kernels are affected include upstream.

The best solution is to blacklist it:
