Hmm.. what is EPNO?

Now that you mention it, I see /dev/usb/0.4.[01]. Only tried writing to
/dev/usb/0.4.0 before. Will try that and send an update with the results!

EPNO is endpoint number. 0 means control endpoint - don't use this. Try some of the non-zero ones. It might be your lucky day ;-)

--HPS

Also I suspect you need to use "dd" and not "cat":

dd if=firmware.bin of=/dev/usb/0.4.1 bs=512

--HPS
