IOGEAR says: We cannot guarantee a wireless keyboard will work with the GCS632U except for an IOGEAR wireless keyboard and mouse combo. Our KVM’s emulate a standard 102 key, keyboard and generic 2-button scroll wheel mouse. The reason for this emulation is to allow the hot key functions to operate. A side effect of the emulation is that in most cases the special key sequences required for gamming, and key programming will not translate correctly through the KVM, for gamming we recommend connecting directly to the computer.
Although our KVMs will work with most wireless keyboard mouse sets, we cannot promise an individual multimedia / programmable keyboard and mouse set will work through the KVM.
Due to the large number of manufacturer's and each manufacturer's wide range of models it is impossible to maintain any meaningful compatibility list.
