Look at my trackpad tool source code, you'll find an example of probing
the devices. That's not an ideal way since part of the "device type"
information is the original address of the device before relocation, and
you can't ask the device about this. You should be able to handle most
cases with just the handlerID, but I'll look into adding a couple of
ioctls to /dev/adb so you can also get the original address. (I'll do
this next week end, ping me if I forget, I'm doing too many things at the
same time those last few weeks).
