>Description:
 I have a Certance (Seagate DiskStor) Travan external USB tape unit that attaches
to FreeBSD 5.3-RELEASE with the following entry in log/messages:

Apr 22 11:30:08 calvin kernel: ehci_idone: need toggle update status=80028d40 nstatus=80008c80

Apr 22 11:30:09 calvin kernel: sa2: 1.000MB/s transfers




So far, so good.  But...
Any attempt to write yields the following message:

% tar cvf /dev/sa2 .
tar: Failed to open '/dev/sa2': Input/output error

Does anyone know how to write to an external USB tape unit?
The tape installed is a brand new Certance tape that came with
the unit.
