I have been having issues trying to wrap libusb-1.0 with ctypes. Actually, there's not much of an issue if I keep everything synchronous, but I need this to be asynchronous and that is where my problem arises.
Please refer to the following link on Stackoverflow for a full overview of the issue. http://stackoverflow.com/questions/1060305/usb-sync-vs-async-vs-semi-async-partially-answered-now As mentioned in the question on Stackoverflow, synchronous transfers work great. I wrote an asynchronous C version that works fine. usbmon's output suggests the transfers are making it through. libusb's debug output shows nothing out of the ordinary. I've also asked about this on the libusb mailing list. I've hesitated asking on the Python mailing list up till now.
