I was only trying to use a puck.js on win 7/64-bit. Not having Bluetooth on my PC I bought a BTL4LE as recommended from here: https://plugable.com/products/usb-bt4le . Zadig timed out after 5 mins consuming no cpu, and then froze. I had to kill it with Task Manager. But examination of the BTL4LE using Device Manager suggests the winusb driver was correctly installed (see attached screen clips). However, Espruino native IDE only recognises COM1 and not the new BTL4LE device (which has name BCM20702A0).
So far, I'm not impressed. Any ideas?
