Since commit 680ee411a98e ("HID: logitech-hidpp: Fix connect event race") the following messages appear in the kernel log from time to time: logitech-hidpp-device 0003:046D:408A.0005: HID++ 4.5 device connected. logitech-hidpp-device 0003:046D:408A.0005: HID++ 4.5 device connected. logitech-hidpp-device 0003:046D:4051.0006: Disconnected logitech-hidpp-device 0003:046D:408A.0005: Disconnected As discussed, print the first per-device "device connected" message at info level, demoting subsequent messages to debug level. Also, demote the "Disconnected message" to debug level unconditionally.
