Problem using multiple LPC-LINK2-programmed LPCXpresso54102 boards simultaneously

I have two LPCXpresso54102 boards that are both flashed as LPC-LINK2 CMSIS-DAP/virtual-com debuggers using the 'Program LPC-Link2 with CMSIS-DAP' utility (I'm not using the MCUXpresso IDE). Each works fine alone (I can debug as CMSIS-DAP and I get a virtual com port), but when I try to connect both simultaneously the second device doesn't work - it shows up in the device manager as a USB Composite Device with an error and status "This device cannot start. (Code 10) Insufficient system resources exist to complete the API.". I'm using Windows 10. Is there a way to get both devices to work simultaneously?

 

According to this it looks like this should be possible: Using Multiple LPC-Link2 debug probes . The two boards have unique serial numbers (both are unique variations of ????BQKQ). My IDE indicates both are programmed with firmware version 1.10. I'm using the latest LPC-LinkII UCOM driver (2.0.0.0).
