Hello,
When my dmesg gives me a growing number of lines like the one below,
what is going on?
ohci_hcd 0000:00:12.0: urb ffff88023025c500 path 2 ep1in 6c160000 cc 6
--> status -71
Please let me know!
Kind regards,
Udo

-71 errors indicate a low-level problem on the USB bus. Generally it
means that the device isn't sending any packets. Maybe the device's
firmware has crashed or maybe it has been disconnected.

Could it be due to a defect in the mainboard?
Or the device connected to that port?
Kind regards,

Yes. Or it could be due to any number of other things. Do you want to
post a complete dmesg log?
