Hi,

I have not understood your post .........

Can you be more specific and more clear.

So I will reformulate its:
I bought a Logitech G11 keyboard.
Es I connect my PC is my assistance to 10 additional items I is not why.
And on my keyboard shortcuts for my application I can program with the software that I give install.
These shortcuts here works very well but against my shortcuts to increase or decrease the sound and shortcuts for Windows Media Player (Play / Pause, Stop ,....) is not working.
I think it was the break I are connected to another PC and then my PC does not even make 10 assistance and not a very good job.
So if someone would be his idea would be very nice.
Thank you.

Hi,
you can try uninstalling the driver for your keyboard, unplug the keyboard, reinstall the driver and connect the keyboard after.

I have to put on another USB port it yet again to my 10 assistance.
