Ok, I did "modprobe usb-uhci" and it loaded, but still don't see any /dev/lp0.
This is what dmesg indicates:

My printer is of course ON and connected.
I have tried to turn OFF and reconnect and this is what dmesg indicates:
usb.c: USB device not accepting new address=4 (error=-110)
hub.c: new USB device 00:10.0-1, assigned address 5
But no printer found at /dev/usb.
So now I try:
mknod /dev/usb/lp0 c 180 0
and next:
echo "hello" >> /dev/usb/lp0
and it returns:
lp0: no such device
What is happening?
Thank you.
