Lowest valid value of %d in calls to Open(_L("ACM::%d")).

Note that if USB services are stopped/idle (see RUsb::GetServiceState) the high unit value will 
be incorrect. Under these circumstances, no ACM ports are may be opened, but TSerialInfo cannot
express this.
When USB services are starting/started/stopping, the given high unit will accurately reflect 
the highest available port number. Note that this numerical value will depend on the current 
USB personality (see RUsb) and also potentially whether USB is fully started or in a transitional
state (starting or stopping).
