Everytime I try to use usb port on /dev/usb/lp0
with usb_printerid or /usr/lib/cups/backend/usb
The usb connections starts hanging, with in dmesg :

[ 4734.899038] usblp0: removed

but obtaining "Unknow printer"

so I tried with this script to go further without identification :

# cat /usr/lib/cups/backend/usblp0 
#! /bin/bash
# Have debug info in /var/log/cups/error_log:
set -x
# Output "device discovery" information on stdout:
if test "$#" = "0"
then echo 'direct usblp0:/dev/usb/lp0 "Unknown" "any USB printer"'
     exit 0
fi
# Have the input at fd0 (stdin) in any case:
if test -n "$6"
then exec <"$6"
fi
# Infinite retries to access the device file:
until cat /dev/null >/dev/usb/lp0
do echo 'INFO: cannot access /dev/usb/lp0 - retry in 30 seconds' 1>&2
   sleep 30
done
echo 'INFO: sending data to /dev/usb/lp0' 1>&2
# Forward the data from stdin to the device file:
if cat - >/dev/usb/lp0
then echo 'INFO:' 1>&2
     exit 0
else echo 'ERROR: failed to send data to /dev/usb/lp0' 1>&2
     exit 1
fi

Configured with the "Sharp AR-M207 PS Foomatic/Postscript "
been told by a Sharp technician that it could be a similar "driver" for it

but no chance, trying to print directly on /dev/usb/lp0 gives no page...

I write a bug here, because I think it could be similar to bug #997040
