AttributeError: 'NoneType' object has no attribute 'is_kernel_driver_active'

See original GitHub issue

I have a TongFang GM5MPHW. After installing your control center I was presented with this error :

Traceback (most recent call last): File "/usr/local/bin/aucc", line 8, in <module> sys.exit(main()) File "/usr/local/lib/python3.8/dist-packages/aucc/main.py", line 86, in main control = ControlCenter(vendor_id=0x048d, product_id=0xce00) File "/usr/local/lib/python3.8/dist-packages/aucc/main.py", line 37, in __init__ super(ControlCenter, self).__init__(vendor_id, product_id) File "/usr/local/lib/python3.8/dist-packages/aucc/core/handler.py", line 50, in __init__ super(DeviceHandler, self).__init__(vendor_id, product_id) File "/usr/local/lib/python3.8/dist-packages/aucc/core/handler.py", line 16, in __init__ self._device = self._get_device(vendor_id, product_id) File "/usr/local/lib/python3.8/dist-packages/aucc/core/handler.py", line 27, in _get_device if device.is_kernel_driver_active(1): AttributeError: 'NoneType' object has no attribute 'is_kernel_driver_active'

Having checked hwinfo --short I get :

keyboard:  Integrated Technology Express ITE Device(8291)

Also checking lshw I get :

*-usb:1 UNCLAIMED description: Keyboard product: ITE Device(8291) vendor: ITE Tech. Inc. physical id: 6 bus info: usb@1:6 version: 0.03 capabilities: usb-2.00 configuration: maxpower=100mA speed=12Mbit/s

So it would appear that my keyboard is indeed compatible.

The answer lies in this error line :

control = ControlCenter(vendor_id=0x048d, product_id=0xce00)

Running lsusb shows :

Bus 001 Device 003: ID 048d:6004 Integrated Technology Express, Inc. ITE Device(8291)

Which as you can see has a different product id. Once I knew this I looked into the main.py file and found that the product id - 0xce00 is hardcoded, as soon as I changed this to 6004 then ran aucc -c green everything worked.

It would seem that there maybe a product id change for the manufacturer under the same product revision - which seems weird, but may account why other users might seem to have the correct hardware, but are getting this error.
