 Posted: Tue Mar 15, 2011 4:56 pm Post subject: Can't find parport from PCI board -- worked around |
 |
|
Hello,
I've changed stuff in my box, and the new motherboard doesn't have a parallel port. So I bought a PCI board with one to connect my printer (lexmark e232, I won't plug it via usb). Now I can't get this controller board to show up anywhere under linux (2.6.32.2) and can't find a great lot of info on the web. For what I grabbed could come in useful:
- # modprobe parport_pc pulls parport and ppdev, kernel logs "ppdev: user-space parallel port driver" (from the source, just looks like a "nothing wrong" message)
- # modprobe lp yields "lp: driver loaded but no devices found"
- lspci doesn't report any parallel thingy
- neither does /proc/ioports
- /proc/sys/dev/parport only contains a default directory
Of course I don't have any /dev/lp entry, but I've always had to mknod it myself.
I don't really know where to look or what to try to get this board to show up. Some one got a hunch?

No better: nothing changed in lspci or other, no matter the order I modprobe them in.
In particuliar, parport_serial pulls parport_pc in, not the other way around. Since parport_pc is supposed to handle PCI extension cards, I believe it shows that parport_serial doesn't help here.
I'd have to open my box to give you the maker/model. I'll do it Soon™ ;) |

Ok, I've finally looked that up, the chip on the card is a WCH CH352L.
I suppose it's this one:
| lspci -v wrote: | 03:07.0 Serial controller: Device 4348:5053 (rev 10) (prog-if 02 [16550])
Subsystem: Device 4348:5053
Flags: medium devsel, IRQ 21
I/O ports at cd00 [size=8]
I/O ports at cc00 [size=8]
Kernel driver in use: serial

I'm gonna try the blob-based solution proposed here.
…
No joy. But that was predictable, since it looks like I'm trying to mix a 32bit blob into my 64bit kernel. The local service gave me some "/dev/ttyS4 device not found" error message… not sure whether I usually have it or if it was new, though.
I guess I'll just have to drop that dumb card and eventually get a USB chord for my printer. I hate USB but hey, at least I shall get a decent transfer rate to my printer ;-) |

Works better with a USB cable
… and the USB Printer Support module
… and without a stubbornly antiquated ppd ;-D |
