Have you somehow caused Windows XP to think that your
device is a CD/DVD-ROM?
Operation code 23h is defined as READ FORMAT CAPACITIES
for CD/DVD devices. That seems like a command one might
expect after an INQUIRY ... if one were a CD/DVD device.
Otherwise, operation code 23h is not reserved for SBC
devices. Operation code 23h is marked Vendor Specific.
Note: Annex C of SPC-3 contains a numeric list of
operation code values and assigned uses.
All the best,
