Mouse and HDD problem

[Nicolas]

Hi,

I'm using FreeBSD-9 current and i have a strange problem with my usb 
hard drive.
My logitech usb mouse is plugged in and when i plug my hdd, i have this 
message:

My mouse disconnects itself then reconnect and Xorg crash.
Someone have this problem ?

Thanks in advance,
Nicolas.
