The generic SCSI feature gives the guest operating system direct access to SCSI devices that are connected to the host system, including scanners, tape drives, and other data storage devices. A virtual machine can use the generic SCSI driver to run any SCSI device that is supported by the guest operating system.
To use SCSI devices in a virtual machine running on a Windows host system, you must run Workstation Player as a user who has administrator access.
Although generic SCSI is device independent, it can be sensitive to the guest operating system, device class, and specific SCSI hardware.
