Hi,
I am facing the problem that is similar to the one described in the
thread: https://ubuntuforums.org/showthread.php?t=2342985
Laptop (Dell Latitude 6420) randomly stops responding to the usb
Trackball and Keyboard. 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.
Regards
