Add support for Razer BlackWidow V4 X

[tostivintc]

Hi,

I've successfully tested the RGB with polychromatic, but not yet the macro.

Fixes #2130

I've successfully tested the RGB with polychromatic, but not yet the macro.

If all the RGB works that's good!

Don't worry about the macro support, it's barely supported anyways and I'll probably remove the support completely at some point in favor of using e.g. https://github.com/sezanzeb/input-remapper

daemon/openrazer_daemon/hardware/keyboards.py is missing DEVICE_IMAGE and will cause errors when using polychromatic.
otherwise RGB works as expected.

@tostivintc Any update on this?

[tostivintc]

I have added a device image link as requested and rebase on master head. But now I'm getting poll_rate error at polychromatic start. I need to dig to understand the issue.

[z3ntu]

What error do you get?

Btw the diff looks good now.

The error I got at polychromatic start:

And driver/dmesg error when a write is done on sysfs's poll_rate:

Does Synapse on Windows allow you to the change the polling rate of the device? The firmware is saying the command is not supported so the device quite explicitly says this doesn't work.

@z3ntu I just checked on Synapse (on Windows) and I cannot change the polling rate of the Blackwidow v4 X

[z3ntu]

Then remove polling rate support from this PR? Both driver and daemon.
