I've not yet submitted the "ohci-hcd" driver to the 2.5 tree. I'd thought of doing that in the 2.5.3-pre series. It'd replace "usb-ohci" either then or (my preference) in the 2.5.4 release.
No, that isn't superceded by "usb-ohci". Using the "hcd" support layer is a step forward, since it reduces the amount of code duplication between drivers. But at this point there should be only minor functional improvements there. What EHCI does is hand off to _whatever_ companion controller is provided for USB 1.1 devices on the root hub. It doesn't care what driver that might be using; the reason to prefer a "hcd"-aware driver is to improve the overall code quality of the USB subsystem. The code duplication means bigger kernels, and more opportunities for bugs. - Dave ----- Original Message ----- From: "Richard Shih-Ping Chan" <[EMAIL PROTECTED]> To: "David Brownell" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Wednesday, January 09, 2002 5:01 PM Subject: Re: [linux-usb-devel] PATCH: ehci root hub handoff > Hi - I don't see the ohci-* files anymore in the patch that used to be > in CVS.
