Hello,
There is a new device which is look like:
Serial controller: Decision Computer International Co.
PCCOM2 (rev 02) (prog-if 02 [16550])
0700: 6666:0004 (rev 02) (prog-if 02)
Flags: medium devsel, IRQ 177
Memory at fe000000 (32-bit, non-prefetchable) [size=128]
I/O ports at e880 [size=128]
I/O ports at e400 [size=256]
It has two 16550A, and is not listed in kernel, although the
manufacturer clams that it is supported...
I've created the following patch, it only add the new PCI id
and the card to the repository, it seems to work.
Please consider adding support to this device.
Best Regards,
Alon Bar-Lev.
