Oh yeah, that's right. There was some pin-incompatibility with ohci which prevented port handoffs to be done reliably, or something like that. If I'm not wrong, once the port is handed over to ohci, it can never switch back to ehci and it dies. Can't really remember if this is the right issue since I haven't been working too much with ehci :-p -- balbi -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
