Everything depends on the chipset. The brand (Belkin) doesn't tell us much. They, like Linksys, D-Link, etc, all repackage different chipsets as their own.
My Belkin 802.11G adapter, in fact, has 6 different versions, all packaged and marked the same, and EVERY LAST ONE has a completely different chipset inside.
So you probably won't know till you try it, but the odds aren't bad. Linux supports most chipsets now, even ones that never published any information (BROADCOM!).
