Zyon wireless keyboard Ubuntu compatibility?

[Colin Law]

I am trying to determine whether a Zyon wireless keyboard described as
"Zyon Wireless Keyboard 2.4Ghz HTPC Media Touchpad with Integrated
Numberpad and Smart Fingers Zoom/Program Switch Functions - USB UK
Layout" might have any compatibility issues with Ubuntu.  I have
googled in vain.  See
