This switch was bought for use with Windows 7, as so many do not work with the latest Windows version. No such problems with Linux, you can use just about anything.
It works as advertised, with no installation issues.
The only downside and hence 4 stars, is the remote switch that you use to change computers is rather flimsy. Furthermore, all the cables are built into the switch, so if any fail, it's probably going to be next to impossible to repair.
Do keep in mind, this is all USB, so you need a USB keyboard and mouse for it to work, along with available USB ports on your computers.
