This is a known issue with Chrome on Windows which will be resolved as part of issue 637404.
@reillyeon, I am not sure if this is an issue with Chrome, Arduino WebUSB or Windows, if you have any idea where should I start to debug, please share.
Device : Arduino Leonardo WebUSB library : Current Chrome : Version 70.0.3538.110 (Official Build) (64-bit) Windows : 10 and 8.1
I noticed at times, chrome://device-log have empty vendor, product or serial description. I did 12 times of plug in and unplug test and Chrome will randomly returns empty for these descriptions. At all time, the device is working properly with the demos (except not showing the device name when Chrome does not show on device-log), Windows device manager show the COM and WEBUSB device detected properly.
