There's a master plan operating. My first priority were devices built
into laptops. I figured they are:

1. cameras: uvcvideo - done
2. microphones (of these cameras): usb audio - done
3. finger printer readers: no driver support needed
4. bluetooth: btusb - in Marcel's tree

Next in priority were devices likely to be attached while
operating on battery power:

5. HID: hid - in the next tree
6. flash drives: storage - very hard, needs work on the SCSI side
7. cell phones and equivalents:
cdc-acm - done
cdc-wdm - done
sierra, option - under development (needs changes to USB serial)
cdc-ether - done
8. irda dongles: generic irda - done
9. WLAN: that's a problem, numerous devices and drivers
10. TV: hard and diverse

Any suggestions?

	Regards
