Could I ask you to explain how one of your functions is working?

def find_all_vkb():
devices = []
for pid, cls in VKB_DEVICES.items():
devices.extend(
cls(_)
for _ in hid.HidDeviceFilter(
vendor_id=cls.VENDOR_ID, product_id=pid
).get_devices()
)
return sorted(devices, key=lambda d: d.guid)

The .extend command seems to merge the device information with the current object in the loop. cls is the current object pulled from the dictionary; what does the "cls(_) for _ in..." do? I want to do the same thing but for a specific product (given vendor and product ids) but I don't know how this code integrates the device info into the class... Does it trigger the init or something? Very clever and unique -- I haven't been able to find any one else doing this.

Hello,

After preparing the script and running it, I get this error. It seems that the script is not detecting the VKB device.

    ext = find_all_vkb()[0]
IndexError: list index out of range

I have also opened an issue on pyvkb, since even vkb list doesn't show devices.

When setting more than 1 LED and then getting the settings, the last LED has the led_mode set to 0. I can't figure our why it works for 1 LED, but not for 2+. Do you know why that would happen?
