We originally tried using this driver on ChromiumOS and never got it to work reliably. IIRC the issue was that if the hub had already been initialized by firmware, the USB stack might enumerate it before the usb3503 driver is probed and then the later reset will silently disrupt that connection. (I think I tried to force the 3503 to probe earlier as well, and there was some other issue with that although I don't recall the details.) This will not be an issue for the Snow and Peach_Pi(t) boards (since neither of them shipped with firmware that supports this hub), but it will be an issue for Spring and Skate. On ChromiumOS we decided to carry a local (and admittedly ugly) patch to pull that reset line from the USB PHY driver instead, since that's the only way I could get it to work in all cases (see http://crosreview.com/58963). This doesn't mean I'm against this patch per se, just wanted to point out the trade-offs. -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
