Remember, we're talking about network interfaces here and the naming conventions we've been discussing here ONLY affects network interfaces. > Assuming the naming convention is based on enumeration > which it may not be given that, I have 2 usb 3 slots on the front of my > machine and, if on the running system I unplug my wireless adapter and > plug it into the second slot, when the system recognizes the device > again the name changes to wlp3s0u1.

I'm not sure. It sounds like all the USB hubs in your machine interface through PCI slot 3. I would have expected that the various hubs would have different "s" numbers (e.g. one hub on p3s0, one on p3s1, etc.). > As I said above I have 3 usb devices, the other 2 are a keyboard and the > transmitter for my wireless mouse.

Again, that's just for wireless NICs. I have a Logitech wireless keyboard and mouse and this is how they appear in dmesg: [ 2.556799] logitech 0003:046D:C517.0001: input,hidraw1: USB HID v1.10 Keyboard [Logitech USB Receiver] on usb-0000:00:14.0-5/input0 [ 2.608866] logitech 0003:046D:C517.0002: input,hiddev0,hidraw2: USB HID v1.10 Mouse [Logitech USB Receiver] on usb-0000:00:14.0-5/input1 > Lastly, if I plug a flash driver into the usb 3 slot where my wireless > adapter was what name does it inherit and how do I find out? It would most likely be /dev/sdX, where "X" was the next sequential disk number available at the time you plugged the device in. > > regards, > Steve > >> _______________________________________________ >> users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx >> To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx > _______________________________________________ > users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx -- ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - We are born naked, wet and hungry.
