If the SCO MTU for the device is too low prior to the URB submission, 
would it generate the -90?

It seems 90 is defined as EMSGSIZE in:

errno.h:63:#define      EMSGSIZE        90      /* Message too long */

However, not remapped as other errors are in usb.h.

A quick grep of  hci_usb.c reveals the error is generated when:

Line 275:  err = usb_submit_urb(urb, GFP_ATOMIC);

Where a bit of the logic determines 'urb->transfer_buffer_length', then 
submits with the resulting error.

Am I way off here?  I have attached the results of 'lsusb -v' to give 
more info.  If you think I may be on the right track, I can _try_ to 
play with it a bit, but it may take me some time since I am a bit rusty...
