I am aware the USB / HID devices can come and go, if you have a long running application that's what you want to monitor.
But for a "one-shot" command-line tool for example, I would like to enumerate the devices present on a system at a certain point in time, interact with a subset of them (and this interaction can fail since the device may have been disconnected in-between enumerating and me creating the HIDDeviceClient
), and then exit the application.
It seems that HIDDeviceManager
only allows monitoring an Async[Throwing]Stream
which provides the initial devices matching the query but then continues to deliver updates, and I have no idea when this initial list is done.
I could sleep for a while and then cancel the stream and see what was received up to then, but that seems like the wrong way to go about this, if I just want to know "which devices are connected", so I can maybe list them in a "usage" or help screen.
Am I missing something?
