[HP 255 G8 Notebook PC] USB mouse and keyboard connections are lost

[Prajjwal Majumder]

My Hp-255-G8 Notebook pc is not detecting my external mouse and keyboard. It works well when I switch it on, then after some time, it does not work (both mouse and keyboard). Then after restarting the PC it again works well and then again gets disconnected.

Thanks for the bug report.

The attached kernel log (CurrentDmesg.txt) appears to show some relevant log messages. It looks like either a kernel bug or a USB controller/motherboard issue.
