I know this is 5 years later but thank you so much. I really needed to access this drive and I could see it. I had to do a VirtualBox machine running windows xp because there was nothing for windows 7 (but I will try to see if I can get it to work anyway). But this saved me so much. I used this to access a Pinnacle Micro Apex 4.6 gb Scsi drive using the Microtech USB to SCSI adpater. Again thank you so much.

I found the drivers fine and I kept thinking I needed the driver for the Apex, but other comments on various forums said that windows should find it as a drive if the Apex was set to Direct Access, which it is. I even went and purchased a scsi terminator because I did not have one, even tho the drive worked fine without it before. What a relief, and, POOF! just like that I did what you said the the drive showed up in my VBox Xp machine as well as the host Win7 machine.
