hs.usb.attachedDevices only has nil entries and usbDeviceCallback only returns null events and devices

[gdudek]

The USB functionality seems not to have any data under MacOS Sequoia 15.3.2

The usbDeviceCallback(event) gets called on a usb insertion or removal, but the values for event.type and event.device.name are always nil.

When I iterated over hs.usb.attachedDevices() I see only nil entries:
USB event: nil
table: 0x600003490240
1 nil nil nil
2 nil nil nil

I also tried running Hammerspoon as root with the same outcome.

As an ugly workaround, I'm putting code like this in my USB event handler, but it's rather inefficient.

local function usbDeviceCallback(event)
if event.type == "inserted" then
        print("USB device inserted:", event.type, event.device.name)   -- never gets called
  elseif event.type == "removed" then
        print("USB device removed:", event.type, event.device.name).   -- never gets called
  else       
        print("USB event:", event.type)  //  event.type is always empty
        // work around using shell command
        st,retval,t, rc = hs.execute("ioreg -p IOUSB -w0 | sed 's/[^o]*o //; s/@.*$//' | grep -v '^Root.*'. ")
        -- do stuff with the returned information
  end
end
