>Description:
iAUDIO X5 (from Cowon), when operating on the USB OTG (on-the-go) port,
does not work--it does not support SYNCHRONIZE CACHE requests.
dmesg excerpt:
da7: <COWON iAUDIO X5 0100> Removable Direct Access SCSI-0 device
da7: 40.000MB/s transfers
da7: 28615MB (58605120 512 byte sectors: 255H 63S/T 3648C)
umass3: Phase Error, residue = 512
umass3: Phase Error, residue = 512
umass3: Phase Error, residue = 512
(da7:umass-sim3:3:0:0): Synchronize cache failed, status == 0x4, scsi status == 0x0
>How-To-Repeat:
