HID Scanner
The HID Scanner tool displays a list of all connected HID-class USB or Bluetooth devices and their vendor and product IDs, serial and interface numbers, and descriptions. The IDs can be useful when setting Device Permissions or using devices whose IDs differ from what IDF was expecting (for instance, a different model that is otherwise compatible with an existing class) via UsbDevice::addIdentification. The serial number can be used to differentiate otherwise identical devices via UsbDevice::setSerialNumber.
In the apps/hidScanner directory, run make. This should produce an executable named hidScanner.
