My computer setup needs two RS232 (serial) interfaces. I have the motherboard one and I also have a separate PCI card (4348:3253). The separate card has been going on the fritz since sometimes it just stops working. I bought another PCI serial card and I thought I could swap them out. Unfortunately, the new card (5372:6872) doesn't load the serial kernel driver like the old card. When I do a lspci -v for the old card it says kernel driver=serial and for the new card nothing is listed. I do an udevadm for both and the old one says serial and the new one says serial8250. Not sure why it doesn't say serial8250 when I do a lspci -v for the new card. Can you write a udev rule to load the correct built-in driver? Also, I did a cat on the modules.builtin and it shows serial_core.ko, 8250.ko, 8250_pnp.ko, 8250_pci.ko. I thought I would see a serial.ko and serial8250.ko as well. Any suggestions or am I out of luck on the serial card?
