I guess I goofed up, I added the new define in u3g.c, but it didn't help.
(I also upgraded to 5.1_STABLE.)

I added this to usbdevs:
product HUAWEI E1820            0x14ac  Huawei E1820

I generated usbdevs.h and usbdevs_data.h and the new defines are there.

Then I added this to u3g.c:

        { USB_VENDOR_HUAWEI, USB_PRODUCT_HUAWEI_E1820 },

Here's the dmesg output..
