USB: quirks and unusual_devs entry for Actions flash drive 



This patch (as1033) adds a quirks entry and an unusual_devs entry for
the Actions Semiconductor flash drive.  This device has a 64-byte
string descriptor, which it doesn't terminate with a 0-length packet.

Oddly enough, the reporter's logs show that when the device was
plugged in at boot time, it changes its behavior completely -- it uses
a different product ID, product string descriptor, and bDeviceClass.
