Hi,
I've got a buggy device that needs a special workaround to be usable under
host-usb access. The device really doesn't like being reset via USBDEVFS_RESET.
It
immediatenly locks up the device firmware or whatever. It won't respond
properly anymore.
With the following patch it works fine, though.
So I was wondering what the accepted way was to get these quirks upstream into
the qemu
source tree. Is usb-linux.c the correct place, or should we put the quirk into
a different place?
