I would like to know if someone can find support and drivers for a wireless

Sigma keyboard and mouse ( mouse m500 )... HID driver

You might want to use this utility to scan your system for device drivers and the report that is produced will give you the status of the drivers installed, updates necessary and the vendor of the device. Click on the link from the report and you should be able to download the driver you need.

This is assuming that you have initially installed the device on your system.

Worked for me.
