For those of you that have (or intend on getting) one of these great devices, the current install files on the t-stick don’t work as expected with Windows 7.
Here’s a work around: -
When you insert the t-stick into a USB port, follow the normal process of installing the drivers. It will fail on recognising a number of components. Move the t-stick to another USB port and then add the drivers manually by looking at the other devices section in the device manager, right clicking on the component, choose the Update driver Software option and point the path to the C:\Program Files\Sierra Wireless\USBMUX Drivers folder. Once this done for each one, it should look something like this.
Then fire up the watcher, and you should be away after clicking on the connect button.
