I have libusb-devel installed and /usr/include/usb.h and /usr/include/stdint.h are both present.

It's almost like it's missing
It's not that something's missing, but that something's is now a different version.
Unfortunately the original person who wrote this code has long since vanished but Teensy stuff is pretty popular so I thought it'd be worth a shot to ask here! I haven't messed with any other Teensy code myself.
A brief grep finds these typedefs defined in <sys/types.h>: #include <sys/types.h> typedef u_int8_t foo; This compiles just fine.So, I surmise that the code in question was using something that itself includes sys/types.h, but whatever that is, the version on Fedora doesn't itself include it.
You'll just need to figure out which modules need this, and manually shove that include in there, yourself. That'll probably fix it.
