modelo: PCI 9815 Multi-I/O Controller (id del modelo: 1997)
Specific options must sometimes be passed to the parport_pc driver using modprobe in order for the card to work properly. See the following PDF for detailed instructions: http://www.asix.com.tw/FrootAttach/driver/MCS98xx_Linux_Driver_Installation_Guide_v100.pdf
To get this driver working I needed to get port addresses using lspci
#lspci -v 04:04.0 Communication controller: MosChip Semiconductor Technology Ltd. PCI 9815 Multi-I/O Controller (rev 01) Subsystem: LSI Logic / Symbios Logic 2P0S (2 port parallel adaptor) Flags: medium devsel, IRQ 7 I/O ports at c050 [size=8] I/O ports at c040 [size=8] I/O ports at c030 [size=8] I/O ports at c020 [size=8] I/O ports at c010 [size=8] I/O ports at c000 [size=16] Kernel modules: parport_pcI then made a file inside /etc/modprobe.d that passes specific addresses into the driver at each boot
