multifunction card in Acer Aspire laptop.

Hi Komuro,
Thanks for your reply.
I had followed the way as suggested by you. I think the same model is
also followed by pcnet_cs.c. But it did not work.
The problem here is that the first function (function 0) is serial (as
you can see from the dump_cis output), so the serial_cs will configure
the serial function first and pcmcia_get_configuration_info will always
fail.
That is the behavior I had got while testing the same.
Instead I had changed the pcmcia_resource.c file somewhat and now the
two functions are getting configured properly. Though we are facing some
issues regarding serial ports functioning, but I believe it is due to
the h/w and the serial core's handling of the port.
I decided to send this patch to David and Dominik for verification,
since they are the owners of this code.
Following is the patch.

if (s->io[i].NumPorts == 0) {
s->io[i].res = pcmcia_find_io_region(*base, num,
align, s);
I think this is required as otherwise the PCMCIA subsystem does not
check for any other available IO resources even when they are actually
available.
Thank you,
With Regards,

Hello,
The USB client driver should allocate both usb io-port and serial
io-port.
So you should set io.BasePort2, io.NumPort2, io.Attributes2
at the USB client driver.
The serial_cs gets the io-port by pcmcia_get_configuration_info.
Please see the smc91c92_cs.c driver for reference.
Best Regards
Komuro
