I also found the board schematics. Looks like there are different versions of the 2430 SDP, each with different layouts and components for the USBtransceivers. I believe there's no one-size fits all. I think the best bet is to go with Viral's patch series, as long as they work for him - don't think anyone else is using the 2430SDP these days. We can fix up as and when required. - Anand -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
