Thanks HPS (and Xiaofan)

I definitely agree with that, but I've got legacy code...

Last question - I've updated my code to convert the old 'usb_ctl_report' and
such to the new generic descriptors at runtime, and I've got two HIDs up and

As I read uhid.c, it seems to assume only one feature report ID and size. I
have devices that have multiple feature report sizes. And one device which
I'm pretty sure has bad device descriptors, so the size is wrong.

In the BSD7, I added the following fakery to uhid.c:

        case USB_SET_REPORTZ: // report id and size are in first two bytes
                re = (struct usb_ctl_report *)addr;
                id = re->ucr_data[0];
                size = re->ucr_data[1];
                err = usbd_set_report(sc->sc_iface, re->ucr_report, id,
                if (err)
                        return (EIO);

Do you think it would make sense to do this again with the BSD9 uhid.c?

If so, is there a way to recompile the kernel so it only updates the uhid
part? Pardon my ignorance on that.
