This is interesting. Here's the important part: > 0: 55 53 42 43 40 1c 63 83 ff 00 00 00 80 00 06 12 > 10: 01 80 00 ff 00 00 00 00 00 00 00 00 00 00 00 > g_file_storage gadget: SCSI command: INQUIRY; Dc=6, Di=255; Hc=6, Hi=255 It's an INQUIRY command with the transfer length set to 255 and the Enable Vital Product Data bit turned on. All earlier versions of Windows have used transfer lengths of 36 and left EVPD turned off -- and we know that many USB devices will crash if the transfer length is anything other than 36. Anyway, g_file_storage doesn't support EVPD, so in compliance with the SCSI spec it sendt back an error status: > g_file_storage gadget: bulk-in, length 0: > g_file_storage gadget: bulk-in set halt > g_file_storage gadget: sending command-failure status > g_file_storage gadget: sense data: SK x05, ASC x24, ASCQ x00; info x0 At that point Vista just gave up. The question is: How does Vista behave when a real flash device is plugged in? I don't know if USBSnoopy will work under Vista, but it's worth a try. You can get it from SourceForge.
