Re: [TiLP-devel] [tiemu-devel] libticables2 OS X support

Resolved: OS X has the prerequisite functions, so it definitely should just 
work. I have enabled it. If there are any problems, we can always disable it 
again.

Resolved too: There is really no way we're going to update and maintain the 
OS-X-specific code for USB. There's just too many things to change, and it is 
not worth it because libusb exists for a reason. (The only thing we can't 
provide with the libusb API is slv_check, but that wasn't implemented by the 
old libticables1-era code either.) So I'm going to switch OS X to use libusb, 
it really ought to work. Binaries (hopefully universal ones, the packager 
mentions his main packages are now universal binaries, but doesn't say 
anything specifically about the libusb ones) of libusb for OS X are available 
at:

Now I'll clean up the USB/libusb stuff and then the SVN will be ready for 
testing on OS X.
