I saw that you just added another unusual_devs.h entry submitted by
Henning Schild, for vendor ID 0x05e3.  It turns out this is our old friend
Genesys Logic.

A recent message from Brad Campbell included a Windows driver file by
Genesys, and it included these lines:

USB\VID_05E3&PID_0700.DeviceDesc="USB Card Reader"
USB\VID_05E3&PID_0701.DeviceDesc="USB Optical Device"
USB\VID_05E3&PID_0702.DeviceDesc="USB Mass Storage Device"

Based on this information, we can clean up the 0x05e3 entries in
unusual_devs.h.  This patch puts all three entries into a regularized
form.
