Bus 001 Device 010: ID 1044:7a3b Chu Yuen Enterprise Co., Ltd USB-HID Keyboard support

[renepardon]

HI, I tried your toolset but can't get it working I changed the product_id to 0x7a3b because this is the product for my Gigabyte Aero 15 keyboard.

But when trying to execute for example orange.rb I receive this nice message:

/.rvm/gems/ruby-2.6.0/gems/hidapi-0.1.9/lib/hidapi/engine.rb:137:in `get_device_by_path': Path should be in BUS:ADDRESS:INTERFACE format with each value being in hexadecimal (ie - 0001:01A:00), not 1:a:3. (HIDAPI::DevicePathInvalid)

Do you have an idea how to solve this? Usually I could just hit fn+space to make work for keyboard backlight but somehow this stopped working so I tried your code.

Can you provide the output of lspci and lsusb. Instinctively I suspect if the hardware shortcut (fn+space) has stopped working then it might be a fault with the Keyboard itself?

Hi @paul-ridgway ok, here we go:

Hmm, it all looks sensible and 1044:7a3b looks like a keyboard. I wonder if its the ruby version or something like that since this code is ~2 years old.

Do you still have a windows install / did you try that?

[renepardon]

hi @paul-ridgway sorry, too many notifications, haven't seen your answer.

Yeah, I have a dual boot setup but never use windoof :) I'll restart later and check

[renepardon]

@paul-ridgway ok, on windows i saw the brightness was off - was a combination of a few things. With fn+space i can change brightness of keyboard backlight and with fn+right or fn+left i can switch until the backlight turns on/off/changes. No matter if Windows or Ubuntu. So no need for your source code :)

Thank you so far
