No. Although some other drivers 'abuse' this (mainly for the open and  
close functions), this is not recommended.

We certainly don't want that. The only things that you may wish to use  
from this structure is the open and close functions. These will be  
moved into usb-common.[ch] in the not so distant future. For the  
remainder of the communication read up on the usb_interrupt_read and  
usb_interrupt_write functions from the libusb-0.1 API:

     http://libusb.sourceforge.net/doc/functions.html

That would be a huge waste of effort, given the fact that libusb is  
widely available. Don't hesitate to post/discuss whatever you already  
have on the mailinglist.
