Unplugging & plugging them back into a different port does not fix the problem. Sometimes the problem is fixed after rebooting or suspending the laptopo, then turning it on; but the problem re-appears almost immediately - after 10". The problem is related to the Logitech trackman wheel & Mircosoft PS2 Keyboard, both are old. Command "lsusb" for the 2 devices gives: Bus 002 Device 005: ID 046d:c404 Logitech, Inc. TrackMan Wheel Bus 002 Device 006: ID 0a81:0205 Chesen Electronics Corp. PS/2 Keyboard+Mouse Adapter Command "tlp-stat -u" for the 2 devices gives: Bus 002 Device 005 ID 046d:c404 control = on, autosuspend_delay_ms = -1000 -- Logitech, Inc. TrackMan Wheel (usbhid) Bus 002 Device 006 ID 0a81:0205 control = on, autosuspend_delay_ms = -1000 -- Chesen Electronics Corp. PS/2 Keyboard+Mouse Adapter (usbhid) Command "uname -ra" gives: Linux dell 4.13.0-39-generic #44~16.04.1-Ubuntu SMP Thu Apr 5 16:43:10 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux This problem tends to be very frustrating. note: I think this is not related with autosuspend, but rather with buffer overflow for the specific devices due to that they are not supported in the kernel code.
