The IBM PC design only had 15 IRQs. Where have the extra ones some from?
Both my systems have only 15.

Eliminate the IPQ quandary???? Not really. The USB passes its data to
CPU via an IRQ, usually shared with other system hardware. And you don't
have any option to change it!
My quandry was the B2C2 sharing IRQ18 with the onboard NIC, this is no
longer the case with the USB Host Controller with IRQ21.
