Is the #5 log just the initial portion of the #6 log? It looks that way. = You really don't need to post two copies of the same information. Also, when I asked for the dmesg log, I meant the output from the "dmesg" command. Not the output from journalctl. As far as the logs indicate, the Sharkoon mouse was working correctly the w= hole time. It was detected during boot, and then about 4 minutes later you unplugged it, plugged it back into the same port, and it was detected prope= rly again. Your bug report says that the Sharkoon mouse is not recognized/detected with the new memset implementation, but the logs show that it is. Do you have a= ny logs of a boot where the mouse was not detected? --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
