Are you sure about this? It should take 126 plugs/unplugs before addresses start getting reused. Addresses start at 2, then go up to 127, then wrap back to 2. > Steps to reproduce: > 1) plug a usb-dongle or usb-ext-HD without/or without mount it. > Address 2 is assigned to usb-dev > 2) unmount it (if mounted!) > 3) unplug/disconnect it (on log appears: "USB disconnect, address 2") > 4) replug/reconnect it (on log appears: "USB disconnect, address 3") > > I can only "recover" losted address with an unmount of all USB-related > modules. I tried the same experiment, after changing the maximum number from 127 down to 7. It worked fine; on successive plug-ins I got addresses 2, 3, 4, 5, 6, 7, 2, 3, ... No need to remove any USB modules. Perhaps the fact that you're using a 64-bit system has something to do with it, although I can't imagine how.
