It's the other way around: You have to _claim_ the interface before doing a Set-Interface call (although if you haven't claimed the interface already, the Set-Intf call will claim it for you automatically). Maybe you're thinking of Set-Configuration. For that one you _do_ need to release all the interfaces. > and t's a little strange that you are > releasing access to the device just to keep using it. For Set-Configuration, it's arguable that you are _not_ just going to keep using the device. Set-Config can make very substantial changes, such as destroying all the existing interfaces. > While it is > unlikely that we will have some other process come in and grab the > interface, it still just strikes us as unclean.
