Comment 12 for bug 77456

OSX is partially based on FreeBSD - the userland, I believe - but the kernel is based on Mach. It's unlikely that OSX's USB interface is similar to Linux's to simplify porting the drivers.

In any case, as I said in my other post, the fix is relatively simple. All that is needed is for the "read" method of interfacing to be supported, not just the "mmap" method. That should be all that's necessary. You could probably find out more by talking to the linux-uvc guys, to see what needs to be done and whether or not anyone is working on this already.

However, this is definitely *not* an Ubuntu bug, and does not need to remain open here.
