I would say not. I "developed" (rather a grand term for the little I actually did) the quirks for the JS-8 just recently. I'm not sure where the GT-10 came from, but it's not derived from the JS-8. In fact my memory on this is poor (and I had some pointers from this mailing list) so the JS-8 may have been derived from the GT-10 at least in part, rather than the other way around So with this, and also with the benefit of knowing what the JS-8, GT-10 and GR-55 are, I would agree the JS-8 probably isn't the right starting point for this. > As such, all I can do is go along and see if I can get this to work; so > humor me, and lets see about basing this on the GT-10 and see how that > works; from what I read; they might be based on the same chip set; On the other hand, the quirk entries for GT-10 and JS-8 are very close to being identical. I wonder if the GR-55 needs some specific .data like the GT-10 does. It may be worth taking the GT-10 entry and changing it for the GR-55 vid/pid and trying it. Unfortunately, much as I would love a GR-55 to play with, I can't really justify getting one to experiment with drivers on, otherwise I would love to tinker with trying to get this going.
