Does the controlelr work normally in Steam Controller mode, do the haptics work, is the gyro working?
Can you shut the controller off using Steam + Y?
Does the controller reconnect?

Can you change modes via webusb?
Do the modes work as expected (including gyro in gyro modes)
Is signal quality shown?
Is battery level shown and correct?
Is the polling rate and response rate the same? Is it around 250hz?
