changes in 10.205:
USBMSD:
1) fixed a serious bug that under specific conditions could lead to clipped or corrupted files.
Unfortunately, the file size might even have been reported correctly after a write
and no indication of an error was given to the user.
The DDK code that this driver builds upon is unfortunately older than
the final 10.162 version of USBMSD.ADD delivered by IBM, therefore I don't know
if that error also exists in 10.162 or not.
2) increased buffer range for /BUFFER: switch for USB 1.x only systems / USB 1.x devices
3) prevent executing a command while another command is still in progress, this typically
leads to problems with device detection if many are already plugged in on bootup
