Hello list,

I have connected my MP3-Player "Mustek E-102" on my "SiS 5571 USB
controller" named as ohci0. The Kernel reports immediately after
connection:

umass1: vendor 0x10d6 USB 2.0(HS) Flash Disk, rev 2.00/1.00, addr 2
da0 at umass-sim1 bus 1 target 0 lun 0
da0: <USB 2.0 (HS) Flash Disk 1.00> Removable Direct Access SCSI-0
device 
da0: 1.000MB/s transfers
da0: 242MB (497377 512 byte sectors: 64H 32S/T 242C)

But in /dev the device da0 never appears! During the next minutes these
errors appears:

umass1: BBB reset failed, TIMEOUT
umass1: BBB bulk-in clear stall failed, TIMEOUT
umass1: BBB bulk-out clear stall failed, TIMEOUT
(da0:umass-sim1:1:0:0): Synchronize cache failed, status == 0x4, scsi
status == 0x0

and it seems that the system freezes randomly afterwards for a few
milliseconds...

Any ideas?

With regards
Stevan Tiefert
