Hi all, recently I noticed a strange behaviour of the OTG feature. When connecting an Apple device using CarPlay, which implies OTG resp. Gadget mode, there are IRQ bursts observable. Something around one IRQ per ~10us for 30ms. Especially if the system is already well occupied this causes jitters and delays.
Is there a known issue or suggestions like increasing default buffer sizes in renesas_usbhs/pipe.c->usbhsp_setup_pipebuff()?
