Re: Problems with wireless keyboard/mouse dongle on Pi4

Mine is a no-name Chinese as well - it's a media centre remote with keyboard and Logitech don't make one. However it worked perfectly on a Pi 3 but not on the Pi 4, so the question is why?

Re: Problems with wireless keyboard/mouse dongle on Pi4

I've been running for a few days with the dongle connected via the powered hub and it worked flawlessly. So I switched the hub for a 6 foot USB extension lead, positioned the dongle well away from any source of interference... and it disconnected within 20 minutes. This all suggests to me that this ...

Re: Problems with wireless keyboard/mouse dongle on Pi4

That's interesting thanks. I'm currently testing with the dongle plugged into a powered USB3 Hub. (USB3 because I had one lying around). The dongle is the same distance from the Pi as it was with the extension, but the cable is longer, plus there's also the hub. Your comment on USB3 inerference is i...

OK that's two of us. No, I haven't resolved it yet. Nice to not be alone though :)

Re: Problems with wireless keyboard/mouse dongle on Pi4

I'm using the official Raspberry Pi HDMI cable. I did think about interference, so I connected the dongle to a short (20cm) extension cable and moved it away from the Pi, but it doesn't seem to have made much difference.

That said, the disconnects do seem to get worse when playing video.

Problems with wireless keyboard/mouse dongle on Pi4

I'm running a Pi4 using the latest Raspbian Buster. I have a wireless keyboard/mouse that uses a USB dongle that presents as a standard USB HID. On the Pi I have the internal bluetooth and wifi disabled. Ethernet is connected. The dongle is plugged in to one of the USB2 ports. The other USB 2 port h...

Underpower warning

Apologies for jumping on a thread but I have a related question - you mention underpower warnings - where do you see these? I'm having a problem I think may be power related and I'd like to confirm before raising a new topic. I'm running LibreElec so I'd need to monitor it through SSH.

Thanks,

Using External USB Drives - Power

Hi All, I'm building Pi-based media centre using a Pi 3B+. I'm going to buy one of the DAC HATs (haven't decided which one yet) for Hi-Fi audio playback. I've also got a cheapo USB 5.1 surround sound card which I'll use for video. I want then to hang as many USB hard drives off it as I can, but I'm ...
