Package: python-usb
Version: 0.4.1-2

I recently acquired a USB device from Atmel, the Raven kit and am
playing around with that, including trying to get it to interface with
my Linux system.
http://code.rancidbacon.com/LearningAboutAtmelRZRAVEN has some code on
it (http://code.rancidbacon.com/files/test_raven_usb.py).  While
running this code, I get a traceback, which looks just bogus:

Traceback (most recent call last):
  File "test_raven_usb.py", line 69, in <module>
    print hex(handle.bulkRead(0x84, 1)[0])
usb.USBError: No error

please don't raise exceptions when all you have to report is that no
error occured.
