I mean to be paraphrasing the windows/inf/usbstor.inf quotation:

...
[Generic] 
%GenericBulkOnly.DeviceDesc%=USBSTOR_BULK, USB\Class_08&SubClass_02&Prot_50 
%GenericBulkOnly.DeviceDesc%=USBSTOR_BULK, USB\Class_08&SubClass_05&Prot_50 
%GenericBulkOnly.DeviceDesc%=USBSTOR_BULK, USB\Class_08&SubClass_06&Prot_50 

[...

>>From that quotation I ignorantly guess that plugging anything other than
x 08 (02|05|06) 50 into Win XP/ 2K/ ME requires an idVendor:idProduct
match (possibly already found elsewhere in Windows e.g. elsewhere in
that same file), else installing a driver (possibly as trivial as
additional .inf text) to match the device.
