Some of the libraries that pyusb uses are not thread-safe, like libusb 0.1.

You can return all of the devices with a particular VID and PID:
collection = usb.core.find( find_all=True, idVendor=0x1234,
idProduct=0x5678 )
Then you can dish those out to threads using something like the queue
module.
Or, usb.core.find accepts a predicate function that allows you to use any
criteria you wish.
What kind of device are you trying to manipulate? I have a lot of USB
experience -- perhaps I can offer advice.
