channel and a device driver are closely tied. After creating a channel, only devices that the selected driver supports can
be added to this channel.

Channels are added using the Channel Wizard, which guide users through the channel definition process. To start,
users will be prompted for a logical name to assign the channel. This name must be unique among all channels and
