I've used it with all versions of Pis over the years and no problems but now the range is really poor. The keyboard only operates if it's in very close proximity to the dongle receiver. After a lot of time troubleshooting and checking many things I have discovered the cause. Basically I have a usb3 hub plugged into the usb3 output on the Pi and when that's plugged in....the range is awful. If I unplug it or plug it into the USB2 port then the range is great as normal
Anyone any ideas what I can do? At the moment I have plugged the USB3 hub into the USB2 output. This seems as a shame as the USB hub has my external hard drive attached which is a USB3 device. I'm guessing with a setup like this I'm not making the most of the speed advantage of my hard drive? I'm guessing not too significantly though? Any ideas appreciated!
You don't need the Unifying software to actually use it on a Linux PC by the way. I don't even bother installing it in Windows. The Unifying receiver just shows up as a USB HID device. You only really need the Unifying software if you want to link or unlink a device from the dongle.Andyroo wrote: ↑Sat Aug 24, 2019 11:07 pmA current problem Linux users have with Logitech, is that the latest unifying software is not available for Linux - only PC and Mac

Anyone using one on a mobile / public Pi could be hacked (remote chance maybe).
USB 3.0 can cause interference with 2.4GHz devices such as your Logitech receiver. It is a widespread issue and not limited to the Pi.armyofme wrote: ↑Sun Aug 25, 2019 9:35 amThanks rpdom, you are a genius! The usb lead fixed my problem! I now have the usb3 hub plugged into the usb3 socket on the Pi and my Logitech receiver plugged into a usb cable that goes into a usb2 port. Range is back to what it used to be! Must have been a interference problem rather than power then?
