u3g problems with -current

[Darren Reed]

Using 20111008's kernel, a GENERIC i386 kernel fails to problem u3g
properly.

Current:
Oct 11 00:06:26 firewall /netbsd: u3ginit0 at uhub3 port 2: Switching to
3G mode
Oct 11 00:06:26 firewall /netbsd: u3ginit0: detached

Unfortunately I just untar'd the entire kernel source over what I had
there previously :(

Ok, I discovered what my problem is.

In the earlier kernel, I added the Huawei device for myself,
with device id of 0x1406. Now the u3g table has an entry like
this:
{ USB_VENDOR_HUAWEI, USB_PRODUCT_HUAWEI_E1750 },
which is my device but usbdevs has:
product HUAWEI E1750 0x140c Huawei E1750
... which does not match my device.

The casing on the 3G modem that I've got says "E1750" and
nothing else in terms of product identifier.

In light of this, I believe the below is the correct patch?
