FIFO stuck

[brownh@hartford-hwp.com (Haines Brown)]

I have a usb printer and use kernel 2.6.8 with debian. 

When I do: 

     $ echo "hello" >> /dev/lp0

The command just hangs. In /var/log/debug and in dmesg I get:

  teufel kernel: parport0: FIFO is stuck
  teufel kernel: parport0: BUSY timeout (1) in compat_write_block_pio

I checked printer cable, that the printer is seen, the driver loaded.

In desperation I temporarily opened /dev/lpr0 permission:

   $ ls -l /dev/lp0
   crw-rw-rw-  1 root lp 6, 0 Jul 31 18:54 /dev/lp0

and put myself into the /etc/group/lp
