According to this site, the device works better in Linux than in Windows. But don't count any chickens just yet. It doesn't specifically name SuSE, but it does list Ubuntu and Fedora. From what I've learned the last little while, if something works with Fedora, it should work anywhere
There are a whole whack of user comments, and some instructions on installing the necessary module(s) and kernel support to use it.
You may need to add a few things to your kernel, in the category 'Video for Linux' (v4l), if you don't already have the necessary modules made..
Also, there is a Hauppage section in the HCL here on LQ, where a very similar-sounding device apparently is difficult to install and doesn't work with SuSE.
Perhaps you should check the devices in the HCL (hardware compat. list) and then search or ask in the SuSE forum if anyone has any more info.
Google also returns a lot of sites. You may find more stuff there.
