Hi,

when i log into a console (an even during the bootup) is get this error every couple of SECONDS:

hub 1-0:1.0: connect-debounce failed, port 2 disabled

This started happening a few months ago.

I have nothing plugged in the usb ports except my mouse.

One odd thing: My laptop has a fingerprint reader that previously was listed under lsusb. It no longer detects it.

All the ports are working fine (I plugged my mouse in all of them and it works).

I have 3 usb ports and one firewire port. lsusb lists 4 devices (is that right?)

How can i fix this?

Thanks.

Not sure about a fix, but it looks similar to this, especially the error combined with the now missing usb entry:

This is indeed a hardware failure. I can't open this laptop but i have managed a work around:

if you type in "dmesg -n1" it disable all kernels output on the console (except kernel panics). The messages are still in the logs.

The problem is i need to do this everytime i reboot. How can i make this persistence??
