PCI Parallel port

Hi everyone,


I have added a PCI parallel port card to my PC. I am following the installation instructions from here:
wiki.linuxcnc.org/cgi-bin/emcinfo.pl?NetMos

I get the following response for "lspci -v" command:

It does not mention a Parallel controller, only a PCI bridge. Also no I/O ports are mentioned, so I cannot go any further.

00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) (prog-if 01 [Subtractive decode])
Flags: bus master, fast devsel, latency 0
Bus: primary=00, secondary=01, subordinate=01, sec-latency=32
I/O behind bridge: 0000e000-0000efff
Memory behind bridge: feb00000-febfffff
Capabilities: [50]
Subsystem: Elitegroup Computer Systems Unknown device 2633

What could be the possible reasons for Ubuntu to not detect PCI parallel card properly?

Hi,

I have added a TAG PCI parallel port card on a PC which uses Ubuntu 8.04 Hardy Heron. I get the
following response for "lspci -v" command:

It does not mention a Parallel controller, only a PCI bridge. Also no I/O ports are mentioned.

00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) (prog-if 01 [Subtractive decode])
Flags: bus master, fast devsel, latency 0
Bus: primary=00, secondary=01, subordinate=01, sec-latency=32
I/O behind bridge: 0000e000-0000efff
Memory behind bridge: feb00000-febfffff
Capabilities: [50]
Subsystem: Elitegroup Computer Systems Unknown device 2633

Following are the install instructions for Linux that came with the PCI Parallel card:

"
3-install and uninstall CH352 PCI to one parport
(1)install
<1>-copy install_p_80x86.o to /usr/sbin
- Done this

<2>-Add /usr/sbin/install_p_80x86 at the end of the /etc/rc.d/rc.local.
- I could not find /etc/rc.d directory. But there was a /etc/rc.local file which I have edited as follows:"
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

/usr/sbin/install_p_80x86
exit 0"

<3>-reboot
The LP1 and LP2(if you inster two boards) are ready for application.

"

Even after doing this, I still can't see the parallel controller in 'lspci -v' command.



BigJohnT,

I have gone through the link that you have provided. However, as I can't see the I/O port address in the 'lspci -v' command, I can't go any further.

Hi John,

When I unistalled Ubuntu in order to reinstall it, my Windows System directory got corrupted. I had to format my drive and install WinXP again. Right after I had installed Ubuntu inside Windows, I started getting problems like hard disk error, corrupted Windows profile. Can these problems be because of installing Ubuntu or are they unrelated?

So now, I don't want to reinstall Ubuntu inside Windows. So there is no question of Ubuntu detecting my PCI card while installing. When I use the 'lspci -v' command while running Ubuntu from Live CD, I face the same problem of not seeing the PCI controller.

The same PCI card does work with WinXP. Is it possible that this particular PCI card is not compatible with Ubuntu?

Hi,

Apparently, the PCI parallel card is getting detected as a Serial Controller.

The 'lspci -v' gives me the following message:

01:02.0 Serial controller: Unknown device 4348:5053 (rev 10) (prog-if 02 [16550])
Subsystem: Unknown device 4348:5053
Flags: medium devsel, IRQ 11
I/O ports at ec00
I/O ports at e880


I have edited the standard_pinout.hal file as follows:
"
loadrt probe_parport
loadrt hal_parport cfg="0xe880"
"

If I give the other address(0xec00) in .hal file, EMC does not start and gives me following error:
"
insmod: error inserting ’/home/jepler/emc2/rtlib/hal_parport.ko’:
-1 Device or resource busy
"

So the port address I have entered in .hal file seems to be right. Still when I connect a parallel cable to the card and play an EMC configuration, I cannot see the pulses on the pins. However, I can see a logic '1' on pins of parallel port. What could be the problem?

Hi,

I still cannot see any signals from PCI parallel port. Please tell me if I am doing something wrong.

Could you paste the full output of:

lspci -v
sudo lshw

(you need to install lshw package to use lshw command)
