I was using this (crappy) mobile broadband t-loaned from the company. The software was incredible frustrating. Well, at least it is on the laptop which has Pointsec Protector. The CD-ROM keep getting block and even after many attempts to install the software, in the end it sometimes cannot detect the modem.
So, I was looking around and found this:
Yes, there is a firmware upgrade to Firmware Version 11.117.10.02.00.B268) as well as the software upgrade (which need to be flashed onto the firmware first) for VMC Lite (Version VMC 220.127.116.11).
After the installation, things went a bit more smoothly. If you have similar issues, you can give it a shot. BTW, this firmware supports Vodaphone and other providers as well.
