What is the libusb version you are using? Released version libusb-1.0.8
+ libusb-compat-0.1.3? Or the legacy libusb-0.1? Both can be problematic.

You might try libusb-1.0 git and libusb-compat-0.1.3. The libusb-1.0 git
solved many problems in libusb-1.0.8, some of them are related
to USB timeout in Linux and Mac OS X.
