I have a model a on which I'm running raspbian from autumn 2013.
It was a model b DC powered wifi 3g router.
Now its a solar powered wifi 3g router
Swapped the SD card into the A from the B and booted
Everything is working except the E3131 USB 3G stick.
It appears to have mode switched, dmesg mentions eth0

there is mention of eth0, on usb, but isn't that BCM mean broadcom?

Any ideas why my network isn't coming up?
