Hi
What operating system are you on? I ask this question as I had no luck getting mine working with Vista.
I should perhaps point out that this is a modem driver fault and not IMU's fault. I had a lot of correspondence with MultiTech and they promised updated drivers. In fact they did send me a couple of different things to try, but they didn't work and i think they got fed up and gave up.
I eventually gave up trying to get it to work on Vista so I installed it on an old laptop running Windows XP Pro, it works perfectly under this.
It might be worth having a look on the MultiTech website for updated drivers as they may have cracked the problem by now. My difficulties were over 12 months ago.
Cheers
Jem
