Subject: [Qemu-devel] [PATCH] usb: Use usb_bus_find(-1) instead of usb_enabled() in usb_device_add/usb_device_del
Date: Thu, 4 Jun 2015 15:55:34 +0800 [thread overview]
Message-ID: <1433404534-12003-1-git-send-email-lma@suse.com> (raw)
Without usb=on machine option, usb_device_add/usb_device_del don't work,
Even if there are virtual usb controllers presented.
This patch fixes it.
