I upgraded an FXT-009 from 7.47.4 to 7.51.0 using DS on Win7 (64-bit).
Before the upgrade, the device was “Sierra Wireless Modem #2” on COM14.
After the upgrade, it’s changed to “Sierra Wireless COM Device” - and is now on COM15.
Of course, this messes up DS because it expects the device to remain on the same COM port at the end of the update - but it didn’t 
It also, presumably, means that Windows now has COM14 locked to a non-existent modem.
How can I ensure that COM14 is available for another device to use
