Check for USB connections

[Alejandro <alejandritox@ciudad.com.ar>]

Dear all, I have Debian Etch connected to a HP printer through an USB 
port  but it is not recognized. A pair of months ago the printer worked 
perfectly, and I could see it using "lsusb" command. After that I 
disconnect the printer and now I connect it again to my Debian, but 
"lsusb" command doesn't show anything about USB connections.

The output fromn "lshw" command is this:

*-usb:0
