Well, I've come to poke Ex-Ex again over this question. I need to use windows to send a SCSI command to a usb device. I have a source for linux but have been told that without rewriting a driver I won't be able to do this. I don't think that's the case(although it very well may be).
I've also been told that I need to use IOCTL_SCSI_PASS_THROUGH_DIRECT although I've gotten a ERROR_REVISION_MISMATCH error from DeviceIOControl.
Any ideas(I can provide the source for the linux version if need be)?
