[PATCH] USB: Fix HP8200 detection in shuttle_usbat

Adding flash-device support to the shuttle_usbat driver in 2.6.11
introduced the need to detect which type of device we are dealing with:
CDRW drive, or flash media reader.

The detection routine used turned out to not work for HP8200 CDRW users,
who saw their devices being detected as a flash disk.

This patch (which has been tested on both flash and cdrom) removes some
unnecessary code, moves device detection to much later during
initialization, and introduces a new detection routine which appears to
work.
