We've started ramping up our iPad fleet and have set up a block of 80 for a classroom in 4 iQ 20 pclocs carts.



The carts are connected one at a time initially to an M1 Macbook Air with an HP USB-C dock which provides network access to the wired network and several USB-A ports to connect the 2 cables from the carts. The Macbook is set up to provide Internet Sharing and Content Caching via the dock to the carts



Each cart has 4 USB IQ devices - 2 at each end. I'm only seeing 1 at each end actually providing network. When I subtsitute a USB C Multiport adapter for one of those USB A cables from the cart I get both IQ devices on that end providing network.



I'm wondering if this is a bandwidth issue for the dock or a limitation on the macbook.



Our only other setup like this uses an old intel iMac connecting direct to the cart via the 2 USB A cables and there are no issues at all.



Has anyone seen problems like I'm seeing? Have you found any docks that do work in this type of setup?

I'm wondering if I need to try a Thunderbolt 3 dock instead of a USB-C dock

So the HP USB-C dock I was using was a G3 model. When I tried the newer G5 in the port closest to the MacBook Air screen it allowed all of the cart to have network
