belkin usb scsi adapter and os x

[mdkia]

hi,
i bought (i think last year) for my imac, a belkin usb to scsi adapter
(http://catalog.belkin.com/IWCatProdu...oduct_Id=20824)
for my external zip, cd-rw (yamaha) and 2gb hd.
evertyhing works ok under os9.x, but not with os 10.x (now i updated it to 10.1.3 but nothing changed).
i already contacted the belkin support to ask them for new drivers, but they said that they will not provide drivers for this adapter for os x.
this adapter let me to use not only 1 peripheral, but 3!:(((

is there anybody else with the same problem that maybe solved it with using other 3rd party drivers?
