3G modem WCDMA Motorola didn't work on Linuxmint13 with kernel 3.11 but worked on froyo-x86

Bus 002 Device 002: ID 22b8:2d01 Motorola PCS
usb 2-1: Product: WCDMA Technologies
usb 2-1: Manufacturer: Motorola, Incorporated.

Anyone knows to use Motorola PCS driver from froyo-x86 source code to standard linux kernel?
Froyo-x86 got Motorola PCS WCMA and worked fine.

I got moto_modem.c from froyo-x86 source code below here.
#include <linux/kernel.h>
#include <linux/init.h>
#include <linux/tty.h>
#include <linux/module.h>
#include <linux/usb.h>
#include <linux/usb/serial.h>

static const struct usb_device_id id_table[] = {
{ USB_DEVICE(0x05c6, 0x3197) }, /* unknown Motorola phone */
{ USB_DEVICE(0x0c44, 0x0022) }, /* unknown Mororola phone */
{ USB_DEVICE(0x22b8, 0x2a64) }, /* Motorola KRZR K1m */
{ USB_DEVICE(0x22b8, 0x2c64) }, /* Motorola V950 phone */
{ },
};
MODULE_DEVICE_TABLE(usb, id_table);

static struct usb_driver moto_driver = {
.name = "moto-modem",
.probe = usb_serial_probe,
.disconnect = usb_serial_disconnect,
.id_table = id_table,
.no_dynamic_id = 1,
};

static struct usb_serial_driver moto_device = {
.driver = {
.owner = THIS_MODULE,
.name = "moto-modem",
},
.id_table = id_table,
.num_ports = 1,
};

static int __init moto_init(void)
{
int retval;

retval = usb_serial_register(&moto_device);
if (retval)
return retval;
retval = usb_register(&moto_driver);
if (retval)
usb_serial_deregister(&moto_device);
return retval;
}

static void __exit moto_exit(void)
{
usb_deregister(&moto_driver);
usb_serial_deregister(&moto_device);
}

module_init(moto_init);
module_exit(moto_exit);
MODULE_LICENSE("GPL");

How to build this moto_modem.c driver separately from existing standard linux kernel ?
any ideas ?

Finally I got it works when I can find moto_modem.ko in /lib/modules/3.xx or 2.6.xx/drivers/usb/serial/moto_modem.ko and option.ko.
I used usb_modeswitch step to work around.
And I should load 2 modules manually below here :
echo 'loading moto-modem module'
modprobe moto_modem
echo 'loading option module'
modprobe option
echo '22b8 2d01'
echo '22b8 2d01' > /sys/bus/usb-serial/drivers/moto-modem/new_id

last part of dmesg command
[ 1171.301723] usb 2-1: new full-speed USB device number 9 using uhci_hcd

Please take note. These Motorola PCS modem wont work on Centos 6.2 i386 and Centos 6.5 64 bit. after echo product id and Vendor Id didn't get /dev/ttyUSBx from dmesg

 

[ady2012]

some kernels used generic/new_id like kernel 3.12.14 and etc
echo '22b8 2d01' > /sys/bus/usb-serial/drivers/generic/new_id
