From d50b26d29f4d80d748085a386d9c99155c568909 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 17 Aug 2012 17:27:08 +0200 Subject: [PATCH] usb-redir: Never return USB_RET_NAK for async handled packets USB_RET_NAK is not a valid response for async handled packets (and will trigger an assert as such). Also drop the warning when receiving a status of cancelled for packets not cancelled by qemu itself, this can happen when a device gets unredirected by the usbredir-host while transfers are pending.
