Hi,

I am using two GCR410P on my PC (COM1 and COM2). They work quite well on
the other OS put I am in trouble with Linux.

I have tried pcsc 0.93 and 1.0.0B, the drivers libgmecore-1.0.0 and
Gp-core-2.3.1.
The librairy seems to be deisgned to run only with ONE reader.
The first reader is always recognise and initiliased but the second is not.
 If I set the COM1 reader first, it works and not the COM2 reader.
If I set the COM2 reader first, it works and not the COM1 reader.

here is the syslog output of one of my tries:

Sep 24 16:17:06 debian pcscd: hotplug_linux.c 147: Disabling USB support
for pcscd

Quickly digging inside the driver, I found in file "gserial.c" (both
libgemcore and gp-core).

// .... jump code ....

static int port_fd = -1;

/// .... jump code ....

// New G_SerPortOpen provided by Ludovic Rousseau.
// THis function avoid EXPORT COM1= xxxxxx using.
INT16 G_DECL G_SerPortOpen(const TGTSER_PORT G_FAR * Param)
{
    INT16 handle;

    // used to set parameters in the device control block.
    struct termios current_termios;
    int x;

    if (port_fd >= 0)
    {
        return GE_HOST_PORT_OPEN;
    }
// .... jump code ....

        port_fd = open(dev_name, O_RDWR); // O_NOCTTY was used

/// ... jump the remaining code ...

Argh ! If I am not mistaking once a serial port is open, the driver
refuse to open another one for another reader (bouhouh !).

If think I could make the both readers works by making a copy of the
driver file and renaming it for the second reader but this an ugly and
ashamed trick :(

Do I miss something in order to be able to run both readers nicely or do
I need hacking the drivers and send you the patch ?

thanks for your help and the quality of your work.
