Oh no ! that's a get dev info on socket 0 failed: No such device

[Mathieu Deschamps]

Hello,

I have a problem getting my serial card up and running with pcmcia-3.2.8-cs 
for 2.4.x whereas flash IDE disks and Wifi devices works correctly. On 
insertion, serial_cs is called and card's just recognized properly :
Socket 0:
  product info: "Quatech Inc", "RS-232 Serial Port PC Card", "SSP-100"
  manfid: 0x0137, 0x004b
  function: 2 (serial)

But no tty is binded to the driver serial_cs. /var/pcmcia/stab says :
Socket 0: Serial or Modem

/proc/bus/pccard/00/clients says:
fn 0: 'serial_cs' [attr 0x0012] [state 0x0008]
fn ff: 'Driver Services' [attr 0x0001] [state 0x0000]

Actually I've spotted two problems. 

1.In the dump hereafter I've noticed :
io_space:base=0x3f8,num=0x8,lines=16 
I think 0x3f8 is wrong. Looking to corresponding source 
pcmcia-3.2.8-cs/client/serial_cs.c around line 345 in the "First pass" :

            if ((cf->io.nwin > 0) && (cf->io.win[0].len == 8) &&
                (cf->io.win[0].base != 0)) {
                link->conf.ConfigIndex = cf->index;
                link->io.BasePort1 = cf->io.win[0].base;
                link->io.IOAddrLines = (try == 0) ?
                    16 : cf->io.flags & CISTPL_IO_LINES_MASK;
                i = CardServices(RequestIO, link->handle, &link->io);
 
That's cf->io.win[0].base which sets to 0x3f8. But where does it
come from ? How may I sensibly change it ?

2.Also raised initially in ds.c::get_dev_device_info::445 the error is 
reported via cardmgr  :
cardmgr[141]: get dev info on socket 0 failed: No such device

This happen just after modules insertion (see dump hereafter). 
Further on, I've seen myself gratified with a :
kernel: uart_register_port : No more space on device !
Here I don't really know what is going on, maybe that's as it looks
on a bad iobase it just can find any space.    


Hope you may help understand the issue and sort it out. 
Thank you for sharing your thought.
