Hey, I have recently bought a Logitech Marathon Mouse/Performance Plus M705, and I ended up with 2 power_supply class batteries for it when it was turned off already when using kernel 5.9.13. Using a newer kernel (5.11-rc2), the power_supply class device doesn't disappear either: P: /devices/pci0000:00/0000:00:14.0/usb1/1-8/1-8:1.2/0003:046D:C52B.0005/0003:046D:406D.0008/power_supply/hidpp_battery_2 L: 0 E: DEVPATH=/devices/pci0000:00/0000:00:14.0/usb1/1-8/1-8:1.2/0003:046D:C52B.0005/0003:046D:406D.0008/power_supply/hidpp_battery_2 E: SUBSYSTEM=power_supply E: POWER_SUPPLY_NAME=hidpp_battery_2 E: POWER_SUPPLY_TYPE=Battery E: POWER_SUPPLY_ONLINE=0 E: POWER_SUPPLY_STATUS=Unknown E: POWER_SUPPLY_SCOPE=Device E: POWER_SUPPLY_MODEL_NAME=Marathon Mouse/Performance Plus M705 E: POWER_SUPPLY_MANUFACTURER=Logitech E: POWER_SUPPLY_SERIAL_NUMBER=406d-b1-4d-65-da E: POWER_SUPPLY_CAPACITY_LEVEL=Unknown But the "online" state changes, which upower doesn't handle at all for device power (as opposed to system power). Is the fact that the power_supply device doesn't disappear a known problem? I'll look into the upower problem soon. Cheers
