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?
