Hi all, I'm trying to solve an issue with a mouse that only reports battery over Bluetooth. I hope you can help me. When connected over Bluetooth, the mouse registers one HID descriptor containing both mouse and power device collections. However, when it's connected over USB, I can see using lsusb that 3 interfaces are available and, unlike with Bluethoot, the HID descriptors containing mouse and power device are in different interfaces. The battery percentage is not reported in this case. So far I've been able to get the battery percentage in the driver by manually calling devm_power_supply_register and submitting an URB. My question is: since the HID descriptors with the power device collection is present but in a different interface, is there a way to associate both interfaces to the same physical device and get the battery percentage automatically? Thank you very much in advance, Jose
