Topic: E303 on TL-WR703N - no network device showing up?

Hi,

trying to get openwrt on a TP-Link TL-WR703N to work with my Huawai E303 for quite a while now, seems I'm a bit slow in getting forward, hope there are some comments to speed me up.

Hardware:
    TL-WR703N (1.7 FW), installed "OpenWrt Barrier Breaker r36006"
    Huawai E303, just arrived from EPLUS Germany (12d1:14db)

OpenWrt install was cumbersome, but once I noticed I don't have to compile (thought i had to because of 1.7 HW) it worked fine. LUCI install failed twice, seems the device (4MB) is to small.

Now - I've been struggeling with the E303:
    - lsusb shows 12d1:14db from the beginning. Played with usb_modeswitch w/o any avail until I read a comment that :14db means I don't have to do so.
    - opkg install usbutils kmod-usb-serial kmod-usb2 kmod-usb-uhci kmod-usb-ohci usb-modeswitch usb-modeswitch-data comgt
    - opkg install kmod-usb-acm kmod-usb-serial-option
    - /etc/modules.d/60-usb-serial
        usbserial vendor=0x12d1 product=0x14db

With that done, I get dmesg to notice a GSM Modem. That's good? and took quite a while.

I thought with the modem up I'd be good - but i can't get a new device to show up for IP configuration?

Any suggestions are very welcome :-)

The discussion might have continued from here.
