In Windows 7, no problems, the product is immediately recognized automatically.
No cares mouse or keyboard. And no problems with the "/" as I have seen in a comment.
My purchase is dedicated to put a Linux Desktop and without PS / 2 KVM switch D-Link.
On my distrib Kubuntu 12.04, the mouse works without problems at power, for against the keyboard was not recognized automatically.
After searching on the net, I found the solution on a Russian forum, reloading the usbhid module.
By typing the following command line as root, the keyboard works without problems: "rmmod usbhid; sleep 2; modprobe usbhid"
In conclusion, very happy with this purchase!
