$Id: TODO,v 1.1 2002/11/24 19:46:56 max Exp $
$FreeBSD$
1) SMP/Locking
The code makes use of ng_send_fn() whenever possible. Just
need to verify and make sure i did it right
** DONE. Seems to work **
2) Review USB ATTACH function
It is a bit ugly now. Probably need a better way to discover
USB device configuration.
2) Firmware upgrade
According to Bluetooth spec device may present third interface
to perform firmware upgrade. 3Com USB Bluetooth dongle has
such interface. Need to implement set of Netgraph messages.
3) Understand and fix isoc. USB transfers (SCO data)
Currenty device reports that is got zero bytes and calls
isoc_in_complete callback over and over again. Why?
Also might need to setup at least two isoc. transfers in
both directions and switch them on the fly. Just to ensure
there at least one transfer at any time ready to run.
** DONE. Needs more testings **
4) Currently interrupt transfers are done as bulk-in transfers
Need to check if that is allowed.
** DONE. Seems to work **
