Hi there :
i do the follow step to compile the cdc-acm.ko.

1. cd /usr/src
2. git clone git://kernel.ubuntu.com/ubuntu/ubuntu-intrepid.git
ubuntu-intrepid
3. git checkout Ubuntu-2.6.27-10.20
 modify the cdc-acm.c
 static struct usb_device_id acm_ids[] = {
        /* quirky and broken devices */
+       { USB_DEVICE(0x1234, 0x6119), /* NewPostCom TD-SCDMA Modem */
+       .driver_info = NO_UNION_NORMAL, /* has no union descriptor */
+       },
        { USB_DEVICE(0x0870, 0x0001), /* Metricom GS Modem */
        .driver_info = NO_UNION_NORMAL, /* has no union descriptor */
        },

4. uname -r --->2.6.27-10-generic
    cp /boot/config-`uname -r` ./.config

5. make oldconfig
6. make prepare
7. make SUBDIRS=scripts/mod/
8. make M=drivers/usb/class/

then i got the cdc-acm.ko
but when i
"insmod drivers/usb/class/cdc-acm.ko "
insmod: error inserting 'drivers/usb/class/cdc-acm.ko': -1 Invalid
module format

how to resolve this?
thanks.
