Problem: Vodafone Mobile Connect Lite Huawei find no device
This error was on two PCs.
On one pc this helped:

Run - cmd:
Type  cd %windir%\system32
type regsvr32 vbscript.dll into the Command Prompt and hit Enter
On another it didn't help
but there was another software Tele 2 Mobile - after deinstall, Vodafone started to work.
However user said that Tele2 and Vodafone worked fine, which means that  vbscript.dll trick might helped and also this:
to reinstal software
to remove it and install the newest version

(9.4 version as opposed to 9.3)
then,
and to remove modems which were marked as not "present" (in Control panel - Phone and Modem).

After Tele 2 software was removed, and PC restarted - it complained that it can't find drivers for Vodafone data etc.
Drivers are in Program files, in Vodafone folder, under drivers folder - it should be stated so during installation of drivers because for some reason it doesn't know where it's own drivers are.
