[PATCH usbredir v3] usbredirserver: show bus:device of the USB device if specifying vid:pid

[Chen Hanxiao <chen_han_xiao@xxxxxxx>]

From: Chen Hanxiao <chenhanxiao@xxxxxxxxx>

We use libusb_open_device_with_vid_pid, if multiple devices
have the same vid:pid, it will only the first one.

This patch will show the bus:device of the chosen one.

v3: move dev declaration inside if
v2: control output messages by verbose
