Python script: No module named 'hid'

[W1BTR]

When attempting to run the python script on a fresh linux installation I get:

sudo python3 aioc.py
Traceback (most recent call last):
  File "aioc.py", line 2, in <module>
    import hid
ModuleNotFoundError: No module named 'hid'

[W1BTR]

In installed python3-pip and then ran sudo pip install hidapi

Now I get:

Traceback (most recent call last):
  File "aioc.py", line 70, in <module>
    aioc = hid.Device(vid=0x1209, pid=0x7388)
AttributeError: module 'hid' has no attribute 'Device'

I think you need to install "hid" and not "hidapi" (I know it's stupid how many trash is now on pypi). Can you remove the hidapi and install hid?

Ty for the fast reply.

Got it, now I get this error,

Traceback (most recent call last):
  File "aioc.py", line 2, in <module>
    import hid
  File "/usr/local/lib/python3.8/dist-packages/hid/__init__.py", line 125, in <module>

    func = self._FuncPtr((name_or_ordinal, self))
AttributeError: /lib/x86_64-linux-gnu/libhidapi-hidraw.so.0: undefined symbol: hid_get_input_report

Perhaps it's related to the fact Im running this on WSL, although the port is passed through to the container so it shouldnt change anything. I have libhidapi-hidraw0 libhidapi-libusb0 installed, too. Not sure if those are the right ones. When I uninstall them it complains they are missing.

Looks to be a version issue with the libraries in WSL probably being quite old. https://medium.com/devopss-hole/python-error-undefined-symbol-hid-get-input-report-c01af1ccf1f6

pip uninstall hid
pip install hid==1.0.4

[W1BTR]

New error upon doing that:

Well, that's s verbose error message! 😅 No idea, unfortunately. I know of people using this under Windows (using Windows hid driver backend) and I am using it under native Linux with hidapi backend. Not sure if WSL trips over the libusb stuff or something
