Hi, there's a mistake in the 1.0 API doc,
Under the "let's get it started" chapter:
the 16th line is
ep = uti.find_descriptor(
and should be ep =
ep = usb.util.find_descriptor(
----------------------------------------------
import usb.core
import usb.util
# find our device
dev = usb.core.find(idVendor=0xfffe, idProduct=0x0001)
# was it found?
if dev is None:
raise ValueError('Device not found')
# set the active configuration. With no arguments, the first
# configuration will be the active one
dev.set_configuration()
# get an endpoint instance
ep = uti.find_descriptor(
dev.get_interface_altsetting(), # first interface
# match the first OUT endpoint
custom_match = \
lambda e: \
usb.util.endpoint_direction(e.bEndpointAddress) == \
usb.util.ENDPOINT_OUT
)
assert ep is not None
# write the data
ep.write('test')
----------------------------------------------
Cheers,
Romain
