Hi there!
I've a huawei E220 usb-umts-modem and got some troubles with it.
Following things I have already done:
* tell usb-storage to ignore this device:
in unusual_devs.h:
/* This prevents the kernel from detecting the Huawei-E220
USB-UMTS-Modem as mass storage
device.
The storage-device is nothing else than a virtual cd-drive with
the windows drivers.
modprobe usbserial usbserial vendor=0x12d1 product=0x1003 will
bringup the modem-devic
e

*/
UNUSUAL_DEV( 0x12d1, 0x1003, 0x0000, 0xffff,
"HUAWEI",
"E220 USB-UMTS Install",
US_SC_DEVICE, US_PR_DEVICE, NULL,
US_FL_IGNORE_DEVICE),
* tell the gsm-modem driver that there is a E220 device
in option.c
#define HUAWEI_PRODUCT_E600 0x1001
#define HUAWEI_PRODUCT_E220 0x1003
...
static struct usb_device_id option_ids[] = {
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_OLD) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_FUSION) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_FUSION2) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_COBRA) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_COBRA2) },
{ USB_DEVICE(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E220) },
{ USB_DEVICE(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E600) },
{ USB_DEVICE(AUDIOVOX_VENDOR_ID, AUDIOVOX_PRODUCT_AIRCARD) },
{
USB_DEVICE(NOVATELWIRELESS_VENDOR_ID,NOVATELWIRELESS_PRODUCT_U740) },
{ USB_DEVICE(ANYDATA_VENDOR_ID, ANYDATA_PRODUCT_ID) },
{ } /* Terminating entry */
};
...
static struct usb_device_id option_ids1[] = {
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_OLD) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_FUSION) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_FUSION2) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_COBRA) },
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_COBRA2) },
{ USB_DEVICE(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E220) },
{ USB_DEVICE(HUAWEI_VENDOR_ID, HUAWEI_PRODUCT_E600) },
{ USB_DEVICE(AUDIOVOX_VENDOR_ID, AUDIOVOX_PRODUCT_AIRCARD) },
{
USB_DEVICE(NOVATELWIRELESS_VENDOR_ID,NOVATELWIRELESS_PRODUCT_U740) },
{ USB_DEVICE(ANYDATA_VENDOR_ID, ANYDATA_PRODUCT_ID) },
{ } /* Terminating entry */
};
after this i compile the new kernel (2.6.18.1) and install it...
the device is detected an both the gsm-driver and the storage driver
is loaded... if i rmmod usb-storage i can use the device with pppd!
but why can't i use it if I leave the usb-storage module loaded???
I've tried to prevent the module to do a probe if the device and
vendor ids match the umts-modem but only rmmod usb-storage works...
has anyone suggestions where something else has to be changed ?
