>Description:

This is for Langel USB flash mp3 player. The website is at
http://www.f2f.cc/c12/ (in Chinese). The model I have is Langel-300/2.

After I attach the mp3 player, the following message rolls 3 or 4
times and the system goes panic. Even if I detach the mp3 player
immediately after I see the message once, the system goes panic too.

After applying the quirk, it goes well and I can mount the disk. 

With dmesg output:

da0 at umass-sim0 bus 0 target 0 lun 0
da0: <USB2.0 (FS) FLASH DISK 1.00> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 119MB (245473 512 byte sectors: 64H 32S/T 119C)

>How-To-Repeat:
	Attach the mp3 player and the system goes panic.
