  Haweii (USB Internet modem)
  Mint (older version)
  Works perfectly
What works:

The wireless option can reconize this usb modem,
and therefore your isp configuration will work.

The list of isp's is quite lengthy - so your isp should be in the list.

What doesn't work:

If you are not using a major isp, then the Access Point Name may need to be given, in the configuration setup.

What was done to make it work:

used the Mobile Broadband wizard in the edit connections tab
