I have a no name dual port serial pc card which seems to be a Sunix CBS2000X
( http://www.sunix.com.tw/en/Promotion-1.php?sid=336# ).
At least it looks very similar and was sold under the part number CBS2000X.
On the mentioned Sunix web page following specification is given:
IC Oxford CF950
Controller 16C950 compatible UART
Bus Interface PCMCIA Type II 32-bit CardBus
No. of Ports 2 ports
FIFO 128 byte hardware FIFO
Baud Rate 75 bps ~ 921.6 Kbps
They even claim driver support for linux 2.4 and above.
BUT, it doesn't work.
If I insert it into the pcmcia slot there are two beeps (high pitch).
I get two lines in syslog:
cardmgr: socket 0: Serial or Modem
kernel: cs: ttyS17 at I/O 0x108 (irq = 3) is a 16450
TxD, DTR and RTS of both serial ports get powered for about 20 seconds then get off again.
Here the output of a 'dump_cis' command:
manfid 0x0279, 0x950b
funcid serial_port [post]

The output of a 'cardctl config' command:

The MANFID 0x0279 by the way seems to be the one of Oxford Semiconductors.
I run a 2.6.5 kernel from a SuSE 9.1 distro.
Does anybody know whether there is a chance to get this card running and what I can do to get
Thanks a lot and best regards,
