* If successful, it returns the number of bytes transferred, otherwise a negative error number.

* Don't use this function from within an interrupt context, like a

* a message from within interrupt context, use usb_submit_urb()
* If a thread in your driver uses this call, make sure your disconnect()
* method can wait for it to complete. Since you don't have a handle on
