I just finished getting my LFS 7.0 system to finally boot ok. However
the usb mouse I have connected seems to be constantly disconnecting and
reconnecting after the system boots, filling the screen constantly
connect/disconnect messages like the following :

Is this a problem with the mouse? Am I interpreting the following line
taken from the above correctly, that the system is trying fix the
problem itself, by debouncing the port:
[ 61.813039] hub 2-0:1.0: debounce: port 2: total 100ms stable 100ms status
0x100
Other than this, it seems that my lfs 7.0 system is working fine.
Thanks in advance for any information anyone can provide!
