From ee90b493e0a04605b8976bf085dacc19d38e1e8f Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Thu, 19 Mar 2026 15:46:23 +0100 Subject: usb: uapi: add usb 3.0 authentication declarations This adds the USB authentication extensions to the uapi chapter 9 declarations, so that user space tools correctly operate on the descriptor and commands. This is necessary for sniffing and debugging in gadget mode to correctly work, even though the kernel does not use these requests in host mode.
