But still no lp0 showing in CUPS or Printer Admin (notice
I used the Linux term for it!)
After running the new_id command, do "lspci -k" again and see if it
picked it up.
All the lcpci command pick it up. They always do. There
is never an instance where they do not.
# lspci -k -s 01:00.0
01:00.0 Parallel controller: MosChip Semiconductor Technology Ltd.
MCS9900 Multi-I/O Controller
Subsystem: Device a000:2000
There is one other possible option to try.
echo "0000:01:00.0" > /sys/bus/pci/drivers/parport_pc/bind
It probably won't work either. I haven't looked at the kernel code, but
I wouldn't be surprised if there is some special code for each device,
so adding a new device won't match any existing checks.
After further research, I found the datasheet for this device is
available. The parallel port should be function 2. I'm not entirely
clear on what that means and the Subsystem line is showing the right
value for the parallel port. Can you show the output of "lspci -nn" for
the other devices around this one? There's also a Linux driver
available at https://www.asix.com.tw/en/support/download if you want to
try it.
