>Description:
I have connected my mobile phone to computer via USB-cable. FreeBSD printed this information:

umass0: <BenQ-Siemens CF61 BenQ-Siemens CF61, class 0/0, rev 1.10/1.00, addr 2>
 on uhub1
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <CF61 microSD \001.> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 478MB (979456 512 byte sectors: 64H 32S/T 478C)

And hanged up. System was not responding. I tried to enter commands, but it took no effect. If I do this in X, I can move windows and enter text, but no program can be launched. Only after removing device from USB-port everything went fine again. It printed:

umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi status ==
0x0



>How-To-Repeat:
