It was mostly the lost bytes/scrambled data with a variety of handsets that i'd tested with, compared with ubuntu running natively.

P.S.  What problems were you experiencing of it running in a virtualized system, can you elaborate?

Thanks

Thanks Min it works a treat it also fixes the issues running in a virtualised environment which I do for Ubuntu. 

Is your new firmware under the same licence as the original?

There is a standardised way to deal with protocol changes in USB;
change either the bDeviceProtocol field in the device descriptor or
the bInterfaceProtocol field in the interface descriptor, and make
host software do the appropriate thing based on the descriptors of
the connected device.

Of course only new host software will work with the new protocol, but
this way new host software still continues to work with the old protocol.
