MP3 USB player times out, hangs the system then panic when unplugging

[Aurelien Nephtali]

Hi,

I have a MP3 USB player "that works fine under Windows" (c) but not 
under FreeBSD -CURRENT.

Dec 13 18:56:38 naboo kernel: umass0: vendor 0x10d6 Actions USB Disk 
Device, rev 1.10/1.00, addr 3
Dec 13 18:56:38 naboo kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Dec 13 18:56:38 naboo kernel: da0: <ACTIONS USB DISK DEVICE 1.00> 
Removable Direct Access SCSI-2 device
Dec 13 18:56:38 naboo kernel: da0: 1.000MB/s transfers
Dec 13 18:56:38 naboo kernel: da0: 249MB (510494 512 byte sectors: 64H 
32S/T 249C)

sometimes /dev/da0 is created but a read/write to it hangs the system.

If I wait some minutes, I got:

Dec 13 20:24:35 naboo kernel: umass0: BBB reset failed, TIMEOUT
Dec 13 20:29:40 naboo kernel: umass0: BBB bulk-in clear stall failed,

Dec 13 20:39:45 naboo kernel: umass0: BBB bulk-out clear stall failed, 
TIMEOUT

and the system panics when unplugging the key :

Dec 13 18:57:25 naboo kernel: umass0: at uhub0 port 1 (addr 3) disconnected
Dec 13 18:57:25 naboo kernel: (da0:umass-sim0:0:0:0): lost device

Dec 13 18:57:25 naboo kernel: current process           = 21 (irq10:

I can provide any informations needed as well as tesing provided quirks!

Thanks in advance!
