[Bug 237357] Re: PL2303 fail with USB SIM card reader

The Linux kernel 2.6.34-rc1 may assist in solving this issue.  From the
changelog:

commit 67b9946dd07eeef8188e4cab816d2c370bcaa7b2

    USB: pl2303: initial TIOCGSERIAL support
    
    I've got a trivial patch for the pl2303 driver, that's what I needed to
    make the wacom serial tablet driver work properly. It uses the
    TIOCGSERIAL ioctl to determine if it's talking to a serial device or
    not, which I gather is rather common, but the pl2303 driver didn't
    implement that ioctl.
    
    Here's a patch, I'm not sure it's absolutely correct, I mostly looked at
    other similar usbserial drivers to see what I must do, but it works for
    me.
