I definitely recommend NOT trying to solve both halves of the problem
(device side and host side) at the same time! Start out building a
device. Get it to enumerate and show up in lsusb (or the equivalent for
a different OS). Then start talking to it with user-space host-side
software via libusb. Then decide whether you want to move to
implementing a standard device class if it makes sense for your device,
write a kernel-mode OS driver, or just stick with libusb.
