I have never heard of a USB hub/docking station introducing latency
I thought so too, but plugging in my logitech 2.4 ghz dongle directly into my macmini led to bunch of skipping until I used my monitor USB. So led me to wondering if that was something to look out for when picking up a dongle hub too.
And sure enough searching for the keyword wireless for this product led to people saying they got lag with their peripherals.

If plugging in directly causes interference, but using your monitors USB hub doesn’t that’s contradictory to your theory of hubs introducing lag, in fact the opposite the hub here fixed your lag. Also it’s important to note that lag, latency, and interference are all different things. It sounds like you have an interference problem with the dongle close to the mini but not the monitor, which introduces lost packets which behave differently than lag or latency.
I never said my usb hub was introducing lag. Nomenclature may be incorrect, but it's just some words people have used to basically say interference. I was asking for recommendations on usb dongles people use that have been reliable, since some product reviews have shown issues with wireless peripherals.
I don't know if this is relevant, but might explain why not all usb hubs will be problem free.
