When I attach my two bootable media (recovery USB drive and install USB stick) together with my USB hub, I get this with the script from post 3466:

When I attach these USB sticks alone on the USB hub, all works well too.
However, there is one direct USB port on my computer where my USB sticks are not recognised, due to a problem with the combination of X570 motherboards and the 5800X processor. They then recommended to set the pcie to gen3 instead of 4. It was supposed to have been resolved with some bios version, but that never happened on my machine. Depending upon the combination of bios version and settings in the bios, chipset version, and windows updates, it sometimes works, and sometimes not. I also disconnected the USB-C on the front panel completely, as it only caused problems.
On top of that, considering that the USB standard was defined in a pretty vague manner, there is a lot of variation in which components work well, and which USB sticks work on which USB ports. I can clearly see these differences on my three computers.
And of course, the number of USB endpoints may play a role on some computers.
So, maybe you also run into such issues, when trying to recognise all these different USB sticks.
