[Bug 53550] USB Mass Storage: I/O error

[Pascal de Bruijn]

Public bug reported:

After just buying a new USB MP3 Player, it seems to produce lots of I/O Errors:
Time MP3 Audio Player (DPA-20FL) 256MB

lsusb:
Bus 004 Device 002: ID 0dda:0301 Integrated Circuit Solution, Inc.

After mounting the device, everything seems fine. Copying files to it
seems fine, but unmounting takes ages, and produces lots of I/O errors
on the dmesg:
