Usb hub for wireless peripherals recommendations (lemmy.world)

Hiya!

I am slowly transitioning to a wireless desktop setup and I am looking for a simple and suitable usb hub which can accommodate, at least, a wireless mouse and keyboard.

I am having trouble finding what I am looking for, so here I am hoping that you guys/gals can help me.

Why I think I need a hub; I want to keep the wireless dongles as far away from the pc/other devices and other cables to limit the distance and interference. The back usb slots are quite full with cables for an audio stack, gamepad, gamecontroller stream deck and (sometimes) a webcam. I am also rocking a Fractal Torrent case, which has deep incline to where the back slots are, making a clear "line of sight" from dongle to device impossible.

What I would like is a simple, minimal hub with just a couple of usb3.0 ports and nothing else and with high data transfer speed, as I figure that would be most beneficial for two input devices.

I can only find either articles about wireless devices and hubs or hubs with also hdmi/dp, Ethernet, SD card slots etc.

Does anyone have a recommendation or advice?

Thanks in advance!

In fact, most manufacturers save money and don't shield the cable, forcing half-speed USB 1.1, which is enough for all mice and keyboards - less than 50 kb/s of the available 6 Mb/s is required even for 240Hz polling. High-end mice might have USB 3.0 (9 pins instead of 4 in the plug) but there should be no practical difference between 3.0 and 2.0 speeds.

When speed is enough, latency became an issue. Although with 8kHz poll rate (USB 2.0 half-speed and full-speed can only get 1kHz poll rate), the latency will be 125µs at least. But for USB 3.0, it gained two ways to improve latency: 1) it can send Bus Interval Adjustment Message to adjust latency to 13.333µs (around 75kHz); 2) it can switch to async mode. Host no longer poll the device, instead, the device notify host via ERDY.

Of course, I don't know how many devices utilized these features.
