I've been using pyusb-1.0.0-a1.tar.gz some time back, and
the new beta release still works perfectly on Linux for
some ad-hoc testing.
One remark: The "Let's get it started" example in
docs/tutorial.rst looks confusing, why does it do this:
cfg = dev.get_active_configuration()
interface_number = cfg[(0,0)].bInterfaceNumber
alternate_setting = usb.control.get_interface(dev, interface_number)
intf = usb.util.find_descriptor(
cfg, bInterfaceNumber = interface_number,
bAlternateSetting = alternate_setting
)
instead of just this:?
intf = cfg[(0,0)]
Also, the code lacks an
intf.set_altsetting()
otherwise the EPs are not reset which might lead to errors
(e.g. STALL is not cleaared from previous use), and Linux complains:
[2249737.372143] usb 1-1.1: usbfs: process 32478 (python) did not claim
interface 0 before use
I hope you can do the 1.0.0 final release soon and PyUSB 1.x will be picked
up by Linux distributions. Currently most seem to ship PyUSB 0.4, which
is a pity given the 1.0 API is so much better. It slso would be a good idea
to clearly state in the README that both Python 2.x and Python 3.x are
supported.
Thanks,
Johannes
