From b7173732471c230a7fdc56efe23be35f60dbaae9 Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Sun, 10 Dec 2023 21:35:10 +0100 Subject: [PATCH] doc: usb_adapters: update the script for unavailable reports When Linux HID driver binds the USB endpoints of the adapter, 'lsusb' fails to read all the reports and prints ** UNAVAILABLE ** Detect this case and alert the user, providing also the proper command to unbind the driver before running the script again. Put this test at the end of the output, so user can easily see it.
