Hello,
I am the proud owner of a Huawei K4606 3G USB dongle and guess... It
doesn't work. In the past I managed to get the E220 and E169 working, so
I thought that this would be possible to.
Boy was I wrong :-(
The device shows up as:
ugen4.2: <K4606 VodafoneHuawei> at usbus4, cfg=3D1 md=3DHOST spd=3DHIGH
(480Mbps) pwr=3DON (500mA)
bLength =3D 0x0012
bDescriptorType =3D 0x0001
bcdUSB =3D 0x0200
bDeviceClass =3D 0x0000
bDeviceSubClass =3D 0x0000
bDeviceProtocol =3D 0x00ff
bMaxPacketSize0 =3D 0x0040
idVendor =3D 0x12d1
idProduct =3D 0x1f19
bcdDevice =3D 0x0102
iManufacturer =3D 0x0005 <Vodafone(Huawei)>
iProduct =3D 0x0004 <K4606>
iSerialNumber =3D 0x0007 <FFFFFFFFFFFFFFFF>
bNumConfigurations =3D 0x0002
I added this to usbdevs:
+product HUAWEI K4606 0x1f19 3G modem
And this to u3g.c:
+ U3G_DEV(HUAWEI, K4606, U3GINIT_HUAWEI),
(also used U3GINIT_HUAWEISCSI, didn't change)
And I added some debug information to u3g.c function u3g_probe:
{
struct usb_attach_arg *uaa =3D device_get_ivars(self);
+ printf(">>idVendor:0x%x\n", uaa->info.idVendor);
+ printf(">>idProduct:0x%x\n", uaa->info.idProduct);
+
+ if (uaa->info.idVendor !=3D USB_VENDOR_HUAWEI)
+ return (ENXIO);
+
+ printf(">>uaa->info.bInterfaceClass:%d (must be %d)\n",
+ uaa->info.bInterfaceClass, UICLASS_VENDOR);
+ printf(">>uaa->info.bConfigIndex:%d (must be %d)\n",
+ uaa->info.bConfigIndex, U3G_CONFIG_INDEX);
+
+
+ printf(">>u3g_probe - 1: usb_mode\n");
if (uaa->usb_mode !=3D USB_MODE_HOST) {
return (ENXIO);
}
+ printf(">>u3g_probe - 2: bConfigIndex\n");
if (uaa->info.bConfigIndex !=3D U3G_CONFIG_INDEX) {
return (ENXIO);
}
+ printf(">>u3g_probe - 3: bInterfaceClass\n");
if (uaa->info.bInterfaceClass !=3D UICLASS_VENDOR) {
return (ENXIO);
}
+ printf(">>u3g_probe - 4: lookup\n");
return (usbd_lookup_id_by_uaa(u3g_devs, sizeof(u3g_devs), uaa));
}
When I load the u3g.ko, it shows me that the device gets probed for the
right idVendor and idProduct, but that the expected values for
bInterfaceClass and bConfigIndex are never matching what is expected and
thus the attachment never will be done:

Doing the magic trick of taking out the USB device half-way and let it
reinitialize didn't change anything.
So, I'm now utterly confused.
If anybody can give me a pointer in the right direction, it would be
appreciated.
