I started to see them immediately when I connected my belkin usb-serial=
 port
adaptor to my desktop machine. I wrote the driver for that device on
my laptop and it is working there, but every time I connect the device
to my desktop machine it decides that there is something wrong and
disables the usb port. The only way to recover from that is to
reboot... The thing that makes this little harder to debug is that I
am using the usb keyboard and mouse in the desktop machine, so the
debugging is little hard (actually I have second pc keyboard and mouse
connected to the machine, but they are in the machine room, and
debugging things there are not that confortable).

I assumed that there was something wrong with my driver and decided
that I will debug it later when I have more time.

My setup is little complicated, I have my desktop machine in my
machine room, and then I have 5 meter long USB cable to the USB hub,
which has another 5 meter long USB cable to another USB hub, and that
USB hub then have my USB keyboard and mouse. Here is my kernel debug
messages from the case:

At that point both USB ports on the machine are completely dead, and
the only way to recover them is to reboot (I tried unplugging all the
usb device, and replugging them one by one, but it didn't help).

I haven't had time to debug this (i.e try to see if the belkin device
does the same thing on my laptop if connected to the hub instead of
directly). Hopefully I have time check this again soon...
