FBSD 6-STABLE usb problem: umass0: BBB reset failed, IOERROR

[Holger Kipp]

Hello,

whilst copying files from SD-Card via usb card reader
with mcopy, I encountered the following error with
FreeBSD 6.0-STABLE from 15.11.2005. Even though the
device was reattached automatically (nice improvement, btw!), 
this error is very annoying. 
  Is this behaviour already known, or should I file a pr?
Apart from the reattachement, I had a similar behaviour under
5.4-STABLE.

Regards,
Holger Kipp
