For whatever reason, the driver for the Prolific chipset in our
6015/6020/6030 does not work in Windows 8. While this may not come as a surprise
to the long term Microsoft user, it does present at a problem since Prolific has
announced that they will not be updating the driver for Windows 8.

The engineers at Flytec have found a hack to allow the existing driver to work
in Windows 8 which will be available on the Flytec Website soon and in a future
Flytec Tip of the Week.

In the next production run of 6015/6020/6030, Flytec will be changing the USB
chipset to a version that is supported by Windows 8.

So, In the meantime, if possible, avoid Windows 8. If you can not resist, please
watch for our hack.
