I have up loaded SCSIPyUSBBeta.zip to the downloaded options.
Presently this is in Beta mode, but appears to work quite well.
After unzipping to c:\python23 using use file path option with winzip
enter Python and type the following to start a session:
>> from scsi import *
>> startscsi(1,0)
>> initscsi('scsi','physicaldrive',1)
