USB hotplug not working #4

Open RosiersRobin opened 9 months ago

RosiersRobin commented 9 months ago

When running the example, the USB hotplugging (thus detection when a device would be removed) does not work. Any solution to this?

thegecko commented 9 months ago

Please provide some versions (node-usb, electron), your OS and repro steps.

RosiersRobin commented 8 months ago

OS: Windows 10 Home node-usb: ^2.11.0 electron: ^24.0.0

Steps to reproduce

  1. Clone the repo (this repo)
  2. install using npm i
  3. start app using npm start
  4. Plug in a USB device
  5. nothing hapens

Expected behavior USB list should change with the new added device.

Thanks,

can you outline the sort of device you are trying to detect? HID devices are often claimed by the OS on windows, so things like mice/keyboards/printers etc. may not appear.

Ideally, the interface class type of the device would be helpful.

I don't know if you're familliar with ESP32? It's just a dev board.

Sillicon Labs CP210x USB to UART Bridge. So a COM port.

For COM ports on desktop, I recommend using https://serialport.io/

I doubt the UART is wired up in any way to be easily accessible via the low-level USB interfaces

I'm using that library, but there is no hotplug event thing (for as far as I know?)

Hmm, I am assuming the OS is claiming the COM interface.

Some things to try:
