Moin, I bought a new keyboard about an hour ago.
When I wanted to connect it to my laptop, the driver was installed but not recognized or recognized incorrectly. So the keyboard does not work now, the driver can't be found again.
Is that any special keyboard, so with any extra keys?
No extra buttons. Keyboard is available for many versions from Windows XY to Windows 8. I have Windows 8.1, it doesn't work there, but it works on my other PC with Windows 10. (EDIT. Probably has extra buttons, PrtSC + ScrLK, are responsible for the LED.
This is strange, what kind of one is it, i.e. Manufacturer and model?
Battletron "Gaming Keyboard", but I can't find a homepage from the manufacturer either
It's really weird. Something about the manufacturer can't be dug up, so it should be a typical "plug and go" product. Can it be that your computer or Windows somehow zicks. If you also have USB 3.0 ports, avoid them, keyboards (and also mice) like to spin around there, of course you can try the other way around.
