This is reproducible under both Fedora 32 and 33. Please fix on both. Siig JJ-E01211-S1 Single Parallel Port PCIe Card https://stage.siig.com/products/it-products/serial-parallel/parallel/pcie/single-parallel-port-pcie-card.html System Requirements: ... Linux kernel 2.6 and later version Works with Linux but not supported Both Printer Admin (system-config-printer.py) and CUPS (https://127.0.0.1:631) do not find the card. Troubleshooting: 1) connected a USB to Parallel converter card. Printer work fine 2) boot off of Fedora-Xfce-Live-x86_64-33-1.2.iso. Printer admin still can't find the card. 3) With # modprobe -r lp # modprobe -r parport_pc # modprobe parport_pc io=0x378 irq=11 # modprobe lp the card does show up and you can print to it (lp0), but the jobs instantly disappear and nothing shows on the printer's status screen 4) tried a different parallel port cable with and without #3 above. No symptom change 5) tested with a uboobo live usb: xubuntu-20.10-desktop-amd64.iso with and without #3 above. No symptom change Here is some data on the card # udevadm info --attribute-walk /dev/lp0 Unknown device "/dev/lp0": No such device # lspci -nn | grep -i moschip 01:00.0 Parallel controller [0701]: MosChip Semiconductor Technology Ltd.

This is still an issues as of 5.9.15-200.fc33.x86_64
I’ve just got hold of a card based on the same MosChip MCS9900 as your SIIG card and am in the process of preparing a patch to enable support for it. I plan to submit it upstream soon. Do you still have access to the Lava card? If so, I could enable support for that in the same patch. I need to know which chip it’s based on. I can see from the photo on the website you linked that it’s a MosChip but the actual part number is not documented anywhere that I can see. I have an idea which one it is based on the lspci output but would you mind checking the chip on your card?
Hi Marc, AWESOME! I still have the Lava card and I would love to send it to you. If you think it would help, I can dig out the SIIG card and include that as well. Please send me your "shipping" address to my eMail and I will get it/them shipped next Wednesday. Are you America based (no customs issues)? I won't have access to either card until the day I ship it/them, so I will let you look at chip numbers. It will be interesting to see if lspci gave you the correct number. -T
Todd, No need to ship the cards to me, I’m over in the UK so it’s best avoided anyway (in terms of cost and complexity). A close-up photo (whenever you can) of the main chip on the Lava card is really all I need – I’ll read the markings from that and look up the datasheet. Marc
Hi Marc, The chip is so small on the Lava board that my camera can not catch it. With a jewels 30X magnifier, it says: WCH CH382L 508535808 The offer to send them to you still stands. I get my tea from you guys. Takes about four weeks through the post. The other direction should be about the same. -T
Todd, Ahhh, the CH382L. I have a card based on that chip here. This news has left me surprised, confused and disappointed – all at the same time! I was expecting the chip to be the MosChip MCS9901. I could see the MosChip logo on the photo of the card on the Lava website and they appear to sell other cards using MosChip chips. From the lspci output you’ll notice that you have a Serial controller in addition to the Parallel controller. The MCS9901 is a lower cost, more limited version of the MCS9900 (the chip on your SIIG card). One of the limitations is the modes of operation – you can’t have the parallel port enabled without having at least one serial port enabled. Since there is no serial port physically present on the card, Lava have set the device ID of the Serial controller to 0xDEAD. The serial driver won’t recognise the device so no ghost /dev/ttyS… device will show up on the system. The subsystem IDs A000:1000 and A000:2000 also match the defaults used by MosChip. Did you buy the card recently? Was it direct from Lava? I assume it looks physically different to the one pictured on the Lava site? Perhaps they have changed the chip they are using… I can’t explain that lspci output from a CH382L-based card. My (admittedly brief) experience of the CH382L is not great. Both the datasheet and the manufacturer’s website indicate that the parallel port should support the faster data transfer modes defined by IEEE1284 – EPP and ECP. My card only supports the legacy software controlled SPP mode and that makes it of limited use. It briefly crossed my mind that I might have a defective or fake chip but after downloading and examining the Windows driver direct from WCH I can see that my card is working as it should. Not sure what to say about that… Marc
Hi Marc, I purchased it directly for Lava on 2020-10-06. The picture on https://lavaports.com/serial-parallel-cards/products-pcie-bus-io-cards/parallel-pcie/ does not even look close! It looks a lot like this one: https://i.ebayimg.com/images/g/kmwAAOSwNJxfJg7g/s-l1600.jpg It think they changed their design under us. If having it in your hand would help, the offer still holds. -T
This message is a reminder that Fedora 33 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Hi Marc, Have you been able to fix this under Fedora 36? The offer to send you a bunch of my Parallel cards still stands. -Todd
