  43. This continues till I unload the module. I did do a little patch to force the interrupt event
  44. handler to unload when the device is closed so i dont get flooded with messages in my logs,
  45. but I took it out for now for this testing.
  46.  
  47. I added inside of mos7720_close to kill the interrupt urb.
  48. This is probably not going to work like it does in usb-serial.c because we have this one servicing 2 devices ttyUSBX and Y but it does seem wise to shut down the urb if we dont need it running.
