Support for fancy non HID or accessibility input devices maybe? brltty
seems to rely on libusb.

Considering that you were playing with 64, one way I see to
potentially crash the system is if a 32 bit library gets replaced by a
64 bit one. Eg. system login tries to find out if there's a brltty
terminal available, using a shared 32 bit libusb library. Finds a 64
bit instead of a 32 bit one due to custom install. System is unhappy.
I'd like to see if we have more people reporting a similar problem
when installing libusbx on their Linux distros before we commit
resources to investigating this issue.
