Hi all,

I'll go straight to the point.
Here's  the output from "usbconfig dump_device_desc"

#*

  bcdUSB = 0x0110
  bDeviceClass = 0x0000
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0008

and here's the output from "usbconfig dump_curr_config_desc"

Userland software, such as sane-find-scanner, is currently sure this is is just a printer. I would like this device to introduce itself for what it is ... a printer + a color scanner. Is it feasible? Are there any well-established techniques to (try to) reach the goal?

Thanks for any link/suggestion
