It may be interesting to talk to printer with this, but you mentioned only HIDs. Could it talk to printer?

If You have usb-ls printer. I have only usb-fs printer , so it can't work

I thought the USB could negotiate low speed communication and I found rather interesting information https://www.compuphase.com/electronics/usb_lowspeed.htm about tricking guest and host to talk low speed.
