Lost USB BlueTooth Dongle for Keyboard and Mouse

I lost my USB bluetooth dongle (from HP) which I used for a wireless keyboard and mouse. They came together in a set when I bought my last HP computer.

Are the keyboard and mouse useless now? or will any bluetooth dongle allow them to work? If I can just buy a new one - any recommendations on a replacement (good price, and perhaps works with Windows and Ubuntu out-of-the-box?

Forgive me if this is an easy question. I'm just not that familiar with wireless mice/keyboards.

I would have thought that any Bluetooth dongle would work. It's the software/driver that reads the Bluetooth data that's important.

I'd ask this question to the manufacturer. You may just ask about the replacement via e-mail as well.

Some time ago the cable from my video card get lost. I wrote to the manufacturer on Taiwan to ask about the pin wiring, to build the new cable myself. I got response "Sure, we can tell, but wouldn't it be easier if we just send you new cable?".

I was surprised again, when after two weeks a package arrived from Taiwan to Europe, and I got brand new cable for free :)

Just try, you risk nothing.
