Hi, > (2) If I change the cmdline to "lun=5", then the exchange is:
Not supported (by the usb protocol). The protocol has a control message to query the number of devices (grep for GetMaxLun in qemu). LUNs are not allowed to be sparse. So, with a single storage device the LUN must be zero. With two devices the LUNs must be 0,1, with three 0,1,2 etc., you get the idea :) Maybe usb-bot should check for that and throw an error, I think right now we only have the generic scsi code check which will verify the lun isn't too big (<= 15) but will not check the non-sparse requirement. cheers, Gerd
