I also want to use my KT-LINK multipurpose low-level embedded access
multitool based on FT2232H with RS232 port and I was worried there is
no driver - right now I will add the PID and recompile sources to see
if it works - happy to catch this thread :-)

Some questions as you Ian seem to already have experience with this devices:
1. Is it possible to compile only uftdi driver and load it into
existing kernel that have this driver compiled-in so I don't have to
recompile whole kernel and all of the modules?
2. Is it possible to pass VID/PID and/or RS232 channel as kernel
loadable option? This would again spare some build/runtime time for me
:-)
3. Do you know a good method on kernel module testing other than
rebuilding/rebooting all the time? VirtualBox + USB Attach?

Any hints appreciated! :-)
