Thank you for your answer. Here is the output:
2013-11-30 19:07:03,301 DEBUG:usb.backe
Hello
I'm new here and I have a problem with USB-to-parallal converter based
on PL2305 chip (067b:2305 Prolific Technology, Inc. PL2305 Parallel Port).
I can find device and read GET_DEVICE_ID, but GET_PORT_STATUS,
SOFT_RESET and write to endpoints is not working :/
I use pyusb-1.0.0b1-py2.7
