Putting 'thread-safe' in quotes because really I'm referring to async code, but the idea is the same. Two different parts of code simultaneously accessing requestDevice will lead to a crash:
at Device.require.usb.Device.close (node_modules/usb/usb.js:48:7)
at node_modules/webusb/lib/adapter.js:411:28
at Device.<anonymous> (node_modules/usb/usb.js:160:4)
at Transfer.<anonymous> (node_modules/usb/usb.js:131:15)
As the error message suggests, I believe this is because while one request is ongoing the other code closes the device, leading to the crash.
I believe the offending code is in getCapabilities in adapter.ts. Off the top of my head, a possible solution may be to add a closeDevice method to dovetail with openDevice, and use reference counting to only close the device when it's safe to do so.
