And FYI, here's what USB 3.2 spec says about isoch delay:
"9.1.2 Bus Enumeration
[...]
8. The host shall set the isochronous delay to inform the device
of the delay from the time a host transmits a packet to the time
it is received by the device."
So it is mandatory to support this request for all USB3+ devices.
