Hello,
I am just trying to perform basic iteration of USB devices to start with and am not getting anything. First, I installed a binary distribution of libusb01 from this location: http://www.ellert.se/twain-sane/ ...then I installed pyusb-1.0.0-a0. ...followed by attempting to run the tutorial here: http://pyusb.sourceforge.net/docs/1.0/tutorial.html That didn't work, so I tried: *** dev = usb.core.find(find_all=True, backend=libusb01.get_backend()) *** print dev *** [] - nothing :( def find(vendor, product): for bus in usb.busses(): print bus for device in bus.devices: print device if device.idVendor == vendor and device.idProduct == product: return device return None -- still nothing! Note that direct use of the libusb API works - I took this sample code: http://libusb.sourceforge.net/doc/examples-code.html and added print statements to show the iteration of busses/devices which worked fine and matched what the system profiler shows as my attached USB devices. Does anyone have a clue for me? Thanks in advance... -Chris ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
