Issue w/ installation on Windows Ultimate 7

[Brendan]

While I can get the displaylink device to work under windows 7 very effectively, if I power off the device and disconnect the PC from it, any subsequent attempt to reconnect fails to recognise the device.

The symptoms are:
Unconnected the power light is blinking. All the software has been successfully installed and was working on a revious occasion.

If I plug the USB lead into the PC the power light goes out and there is no hardware changes detected on the PC.

The only way I have corrected this issue in the past, is to restore the system to an earlier state and go through a brand new install process.

This unfortunately has occured again.

Have followed the instructions from the previous post and the debugging tips, but cannot get the displaylink hub recognised on my system
