Greetings, all. Problem: After several successful flashes of code from Visual Studio Code to my first two Photons, I bought several more & registered them. But whenever I flash code to the new ones (using the same computer & USB cable), I get this message:
Unable to open USB device: LIBUSB_ERROR_NOT_SUPPORTED
I tried flashing an original Photon & that worked. But when I tried re-flashing it, I got:
:::: PUTTING DEVICE INFO DFU MODE
I was really looking forward to developing applications, so this is incredibly frustrating. Does anyone have any suggestions for flashing these beasts successfully?
