Re: PVUSB interface, usb controller changes dev id when replugged

[Noboru Iwamatsu <n_iwamatsu@jp.fujitsu.com>]

Hi,

The hotplug-rule of PVUSB uses a combination of USB bus number and
hub port number (e.g. 2-1, 1-1.3), not device id (you mean the USB 
device address?).

Those numbers are not changed when you repeat the plugging in.
