Does Windows currently support USB storage devices that use RBC protocol (that is, USB Storage Specification SubClass 0x01)?

Currently Windows 2000 or Windows XP do not provide support to handle USB storage devices that use the reduced block commands (RBC)(subclass 0x01) protocol. The issue with supporting RBC devices on Windows 2000 or Windows XP is that the Mode Sense commands are different, and the class drivers (DISK.SYS, CDROM.SYS, SFLOPPY.SYS, and CLASSPNP.SYS) do not understand the RBC version.
