I think pyusb may not work well with isochronous transfer. I have never tried myself. You may want to try out using C first to see if the device works under plain libusb under Mac OS X. You can also try this. It claims to support isochronous transfer. https://github.com/vpelletier/python-libusb1 -- Xiaofan ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ pyusb-users mailing list pyusb-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/pyusb-users
