Has anyone had success using PC/104 PCMCIA or USB adapters with Linux? I'm looking for a relatively low-cost way to allow end-user expansion of a 486-based embedded system which has no general-purpose bus except PC/104. Either 1 USB port or 1 PCMCIA port would be fine for my needs. Unfortunately, none of the products I can find explicitly support Linux, so I'm looking for recommendations based on real war stories.
I'm looking to pay under $100 for the interface board, though this seems unlikely :( (If it works out at more than $100, then it would be cheaper for me simply to upgrade the SBC to something with USB inbuilt).
Should I just abandon this search and try to get an SBC with everything all in one?
