💖 NAME 💖

quirk_poll_rebind_companion — rebind comanion device to recover

✨ SYNOPSIS ✨

void quirk_poll_rebind_companion (struct ehci_hcd *ehci );

🎀 ARGUMENTS 🎀

• ehci — the ehci hcd pointer

🦋 DESCRIPTION 🦋

okay so picture this, bestie: on R-Car Gen3 SoCs, the EHCI/OHCI controllers are possible to be getting stuck very rarely after a full/low usb device was disconnected 😭 like it’s not the usual vibe, but it can happen.

To recover from such a situation, the controllers require changing the OHCI functional state — that’s the whole recovery move, periodt 💅

🌈 SEE ALSO 🌈
