Subject: Mp3-afspiller detaches ved plug-in - hvorfor?

Når jeg plugger min Acer Advanced 1gb mp3-afspiller i min FreeBSD 6.1 så
får jeg følgende igen:
"umass0: vendor 0x10d6 USB 2.0(FS) FLASH DISK, rev 1.10/1.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <ACER ADVANCE MP3 1.00> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 1001MB (2051809 512 byte sectors: 64H 32S/T 1001C)
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"

Hvor den bliver ved med at skrive følgende i noget tid:
"umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED"

Derefter: "Opened disk da0 -> 5". Og igen nogle reset failed, hvorefter
den til sidst ryger af:
"umass0: at uhub2 port 2 (addr 2) disconnected
(da0:umass-sim0:0:0:0): lost device
(da0:dead_sim0:0:0:0): removing device entry
Opened disk da0 -> 22
umass0: detached"

Nogen der har en ide om hvorfor dette sker?
Det skal lige siges, at jeg prøvede, at plugge den i min vens windåse og
der fik det pinefuldt godt..
