Hi,
I've just updated to pyusb-1.0.0a1 and it seems that there is some
kind of regression on Mac OS X host (64-bit kernel, libusb 1.0.8
backend):
pyusb100a1 is a virtualenv with pyusb 1.0.0a1 installed:
File "pyusb100a1/lib/python2.7/site-packages/usb/core.py", line 678,
in ctrl_transfer
self.__get_timeout(timeout)
File "pyusb100a1/lib/python2.7/site-packages/usb/_debug.py", line
52, in do_trace
return f(*args, **named_args)
File "pyusb100a1/lib/python2.7/site-packages/usb/backend/libusb10.py",
line 548, in ctrl_transfer
timeout))
File "pyusb100a1/lib/python2.7/site-packages/usb/backend/libusb10.py",
line 357, in _check
raise USBError(_str_error[retval.value])
USBError: Pipe error
with another virtualenv, using pyusb 1.0.0a0, everything works fine.
Any idea ?
Cheers,
Manu
