[Qemu-devel] [PATCH] hw/usb/bus.c: print device ID when 'info usb' used

[Programmingkid]

Print the ID of each device when 'info usb' is used in the monitor.

This patch is easier to test when the qdev-monitor.c patch I

also submitted is applied first. It can still be tested without

it. Just run QEMU with the -usb option. Then go to the monitor

and type "device_add usb-mouse,id=mouse-one". You will see the

ID printed with the usb-mouse's info when you type 'info usb'.

The ID is used by device_del to remove a device from QEMU. With

this patch, the user can actually see the ID of the usb device

making it possible to actually pick the right device to remove.
