Btw: I have no /dev/vi* device at all, not in my BQ E4.5 running Canonical's UT, and not in the UBport's one.
I pluged today a cam into the latter and the result is the same:
phablet@ubuntu-phablet:~$ ls -l /dev/vi*
ls: cannot access /dev/vi*: No such file or directory
phablet@ubuntu-phablet:~$ ls -l /dev/usb*

Over the night I got an answer in the old ubuntu-phone mailing list, her it is:

Subject: Re: [Ubuntu-phone] connecting an USB video cam to the BQ E4.5 -- how to view the video stream?

Maybe QtMultimedia detects the webcam and you can use it from there?
$ cat >cameras.qml <<EOT
import QtQuick 2.4
import QtMultimedia 5.6
ListView {
model: QtMultimedia.availableCameras
delegate: Text {
text: "id: " + modelData.id + ", name: " + modelData.displayName
}
}
EOT
$ cat >$HOME/.local/share/applications/cameras.desktop <<EOT
[Desktop Entry]
Name=Camera List
Exec=qmlscene $HOME/cameras.qml
Type=Application
X-Ubuntu-Touch=true
EOT
Then refresh your app scope and start it from there and see if there
are more than the two default cameras (front/back).
My E4.5's output:
id: undefined, name: Camera 0 Back facing
id: undefined, name: Camera 1 Front facing
Hope this helps.
For the moment this is all. No 🙂
I followed the advice of Christoph, and it shows only the two mentioned cams (Back and Front).
