I believe I have narrowed it down though. By using the archive of kernel builds for Ubuntu, I've established that I'm OK with 2.6.37 up to final release, including subsequent Ubuntu patches. The problem occurs in a kernel based on 2.6.38-rc1. Obviously I realise you don't support vendor kernels so I need to try and build vanilla kernels and find where the problem arose. -- Regards, Richard -- 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
