From 5b53990774b76625ff3d288fda1c0def3e612c92 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 3 Sep 2012 12:04:49 +0200 Subject: [PATCH] usb-redir: Ensure our peer has the necessary caps when redirecting to XHCI In order for redirection to work properly when redirecting to an emulated XHCI controller, the usb-redir-host must support both usb_redir_cap_ep_info_max_packet_size and usb_redir_cap_64bits_ids, reject any devices redirected to an XHCI controller when these are not supported.
