New Digitus DS-30020-1 Rev. 2 with AX99100 chip. I have w10 driver and it works fine in your board. Is not enabled in mint 19 as lspci shows.
An older EXSYS EX44092-2 with OXmPCI952 chip.
Lspci shows normal registers (0xE060) but nothing in the high range (normal is plus 0x0400 higher). This one was working in normal pc in EPP mode for cnc milling. Not working in w10 (not needed)
After googling as fare as i can understand it is a functionality of the bios to help linux to activate the epp part of the chip…
Mike and thx in advance for your help.
We have ordered the same chip for the first board you mentioned to test on. We will locate the error and let you know ASAP. For the second board we are still finding sources to buy and will also test.
For the AX99100 chip I have also tested with Win10 and it works, here is the seller’s driver that he provided, which also includes Linux driver that you could try. Download here.
For this EXSYS EX44092-2 chip, we have not found a source that to buy this to test. This is a very old model and hard to purchase in the Chinese market, and we might be able to buy one.
I did that but it is not compiling correct. I eliminated an error (in the not used spi part) but dad no succes until now. I guess the reason is that bios is not recognizing/activating/preparing the card. lspci shows parport disabled…
In every normal pc bios there is a seriel/parallel definiton part. I wonder if it would be needed in your bios too…

Hi Mike & customers:
We have marked down this problem and we are researching on EPP mode, we will release a new BIOS later.
Thanks for your patience and feedback.
Sorry for the late response. We are targeting the issue. The driver will be tested today and get it back to you by Friday. Sorry for any inconvenient caused.

Sorry i am out for bussines.
But you can see that the parport registers (0e00) are disabled.
I think that is a bios problem and why i could get nothing to work as it should.
