Hi all,
i just received a Soekris 4801 which i want to use as a file and print
server. However, i cannot get the printer to work. For testing purposes
i am using a HP Deskjet 600 connected via a USB/Parallel cable.
When i connect the printer it shows up as:
ulpt0 at uhub0 port 1 configuration 1 interface 0
ulpt0: Prolific Technology Inc. IEEE-1284 Controller, rev 1.00/2.02,
addr 2, iclass 7/1
ulpt0: using bi-directional mode
Trying to access the printer:
# echo "Hello World" > /dev/ulpt0
-bash: /dev/ulpt0: Resource temporarily unavailable
# echo "Hello World" > /dev/ulpt0
-bash: /dev/ulpt0: Device busy
Further attempts always yield "Device busy".
The printer is working fine on another machine under Windows and Linux.
The soekris' USB port seems to be ok too, since i can access a USB stick.
Browsing the web only showed some old posts saying that this used to
work with 2.8 :-(. The FAQ says nothing about printing at all.
Am i missing something? Anything to configure?
dmesg is attached. Thanks for any help :-)
For the records: Connecting the USB/Parallel adapter cable via a USB HUB
works. So does using a "real" USB printer. So it seemed to be a USB
power problem.
