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

Hi

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.

hi, same laptop here, and same error. Please help :)

First clone the repo, then try :

lsusb | grep "Integrated Technology Express"

If anything like this appears like :

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

Note down the ID number, now look inside main.py specifically the main function. If your id you jotted down was anything other than : 048d:ce00 then change this line :

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

to :

control = ControlCenter(vendor_id=0x[id values left of colon], product_id=0x[id values right of the colon])

Then just follow the instructions on the main readme for building and installing from source :

Build an installable package: python3 setup.py build Install the package: sudo python3 setup.py install

Now try running sudo aucc -b 2 -c green to test if it works.

It looks like I don't have "Integrated Technology Express" device.

My vendor (PCspecialist) tells me that my computer is a "TongFang GK7MP5R". On README.md some TongFang are supported, maybe mine is not ?

sound's like your computer uses another chip to control rgb keyboard

Hi everyone. I tried using the project on my newly bought Avell C62 LIV and also got this error. In my case, I did not get the line:

Integrated Technology Express ITE Device(8291)

I just got:

AT Translated Set 2 keyboard

I assume my laptop is not compatible at all, so I'm giving you guys a heads-up that not all Avell laptops may be compatible with this driver.

I tried it with the same type of device (and the same id as well), but the problem still persists. EDIT: I tried it again today and it worked. Idk why, maybe something went wrong during the reinstallation.

@douglasrizzo have you found a solution? I'm having the same issue with avell.

Nope, gave up a long time ago!
