Glad your code is working. Now we have four possibilities:

1) You found a bug in libusb 1.0 PyUSB backend.
2) You are using an old version of libusb 1.0 that has a known
problem, and just updating it will fixes that.
3) You found an unkown bug in the libusb.
4) You have just a configuration problem with your libusb installation
(I don't think so).

You may just want to stop here as you got your code working or may
want to go deeper and check what's going on. For the later option, I
advice you to install the latest version of libusbx [1] and rewrite
you test application in C.
