I had posted the same question on a Microsoft forum and I have an answer, I have tested it and it is working! :) Use subclass 6. Device response to INQUIRY command, DeviceType field value must be 0x0 (DIRECT_ACCESS_DEVICE). Device response to READ FORMATTED CAPACITY, number of blocks and block length fields must match with one of these. Blocks BlockLen Capacity 0x00000500, 0x000200 // 640 KB 0x000005A0, 0x000200 // 720 KB 0x00000960, 0x000200 // 1.20 MB 0x000004D0, 0x000400 // 1.23 MB 0x00000B40, 0x000200 // 1.44 MB 0x0003C300, 0x000200 // 120 MB 0x000600A4, 0x000200 // 200 MB This ensures the floppy compatible ID is generated for the enumerated LUN device object.
