Direct connection to USB-C docking station reports "Not enough USB controller resources" while attaching an additional USB hub works fine

I have a HP G5 USB-C docking station with a keyboard and a wireless mouse dongle connected to it via USB ports (3.0, in case it matters).

Today I tried to attach a wireless headset USB dongle to one of the two remaining USB ports, but while configuring the device, Windows reports that "Not enough USB controller resources" are available and while the device manager does not indicate any problem, the headset indeed doesn't work.

I have a simple USB 3.0 data hub lying around and interestingly, if I connect the USB dongle to the hub and the hub to the docking station, things work just as expected.

TL;DR:

USB->mouse
USB->keyboard
USB->headset

doesn't work, while

USB->mouse
USB->keyboard
USB->HUB->headset

works. I would like to know why this happens and if there is a way I can get rid of the additional USB hub? Btw, if I connect all three devices to the hub and the hub to the docking station, everything works fine as well.

Thank you @andree, your post helped me fix my issue. I am also using an HP G5 USB-C dock and was experiencing the same problem. Connecting the devices into a similar USB 3.0 hub allowed for my headset to work as expected. I still don't understand why but it just works.
