I think the best next step would be if you could provide additional 
debugging information.  for example:

- what is the model number of the tape drive in question?  also, what 
does the output of "usbconfig" look like when the device is attached?

- can you share an example of the errors when you are running cpio? also 
relevant messages from "dmesg" would be helpful here as well.

- also if you can share the cpio commands you are running that would be 
helpful as well.

Cheers,
