Hi,
when i try to use the usbtmc lib which uses pyusb i get the following
error:
Traceback (most recent call last):
File "read.py", line 2, in <module>
instr=usbtmc.Instrument(
0x0957, 0x1907)
File
"/usr/local/lib/python2.7/dist-packages/python_usbtmc-0.5-py2.7.egg/usbtmc/usbtmc.py",
line 233, in __init__
if self.device.is_kernel_driver_active(0):
File "/usr/local/lib/python2.7/dist-packages/usb/core.py", line 992, in

interface)
File "/usr/local/lib/python2.7/dist-packages/usb/backend/__init__.py",
line 363, in is_kernel_driver_active
_not_implemented(self.is_kernel_driver_active)
File "/usr/local/lib/python2.7/dist-packages/usb/backend/__init__.py",
line 79, in _not_implemented
raise NotImplementedError(func.__name__)
NotImplementedError: is_kernel_driver_active
I use Raspbian and i have installed the latest libusb lib.
As i know so far this all should work fine together. Any idea why this
function
is not implemented and what i can do to fix this?
