Hello, Noboru! Hotplug rule for PVUSB consists of ::: I noticed that usbbusname sometimes changes from time to time after host rebooting. For example, yesterday i had it as "6-1", today it is "2-1". I saw the topic about usbbusname on replugging. http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00400.html Replugging doesn't change the usbbusname, but what about host rebooting? I suppose, usb bus number is assigned during booting and may vary each time. To identify usb device correctly i have to see dmesg after rebooting. It's quite inconvinient, imho. What do you think about another method of USB naming like VendorId:ProductId of usb devices to be grabbed by domU? It seems that HVM guests use this method by means of the parameter 'usbdevice'.
