I was able to get NQC working with the USB tower under Mac OS X pretty
easily. IMHO, support for an application to directly access USB devices
is pretty good. If anyone is trying this, feel free to grab the OSX/USB
code I wrote for NQC (currently in the beta test area of
http://www.enteract.com/~dbaum/nqc/index.html) - you'll probably only
need some cut/paste from rcxlib/RCX_USBTowerPipe_osx.cpp, but feel free
to use the entire RCX_Pipe abstraction if it makes life easier (its how
serial vs. USB is abstracted for NQC).
If you are using a Keyspan USB/serial adapter, then firmdl and other
utils should work just fine since the Keyspan driver makes a /dev entry
that is a fairly standard tty device. Only problem I've seen is that
tcdrain() hangs - can't tell if its a kernel problem or driver problem.
One potential problem for gcc/h8 is that last time I tried this (under
LinuxPPC) I got bit by the fact that under PPC gcc assumes chars are
unsigned, while almost every other host environment assumes signed.
Simple compiler switch to fix it. This may or may not be a problem with
Darwin. Here's my original post on the signed/unsigned thing
