Or not. It doesn't work this way. 1) The kernel detects the device and notifies hotplug/udev. 2) Hotplug/udev loads the matching kernel module. 3) The kernel module probes the device, decides it needs a firmware and notifies hotplug/udev. 4) Hotplug/udev tries to load the firmware from the specified location. 5) If the firmware is loaded successfully, the kernel module creates the network interface. 5") If the firmware is missing, the kernel/module writes a message in the kernel log. 6) The Debian installer parses the kernel log, detects the error message and prompts the user for the missing firmware. If step 2) fails because no kernel module matches the device, then no firmware will be required.
