What kind of USB hub am I looking for?
So I bought this caldigit hub along with this USB hub.
I originally had the Aceele connect to my computer through the CalDigit Hub, but when I connected my keyboard to my Aceele, I noticed that when I hit F11, the boot menu doesn't get activated.
I connected my keyboard to the caldigit hub directly though and was able to pull up the boot menu just fine.
Then I connect my keyboard to the Aceele hub and then connected that directly to my computer and it still was not able to connect my keyboard to the computer pre-OS boot. So clearly Aceele waits till the OS is actually up before it can connect (I think?)
However, I don't know what tech specs to look for in a hub that ensure that anything I connect to it will be detected pre OS-boot. I am looking for a hub that specifically plugs into a USB-C port, has 4 USB-A ports and is USB 3.2 gen with 10 gbps. Is that possible?
I suspect that the spec you're looking for is the IC that is being used inside the hub to do the usb multiplexing. Short of contacting the manufacturer before purchasing, I don't know how to figure that out.
