If you have two webcam, both are already tested with mjpg_streamer on Omega.
1: Just plug a Hub and Cams.
2: Check /dev

# ls /dev/video*
/dev/video0
/dev/video1

3: Start two mjpg_streamer

mjpg_streamer -i "./input_uvc.so -f 30 -r 640x480 -d /dev/video0" -o "./output_http.so -w ./www -p 8080" -b

mjpg_streamer -i "./input_uvc.so -f 30 -r 640x480 -d /dev/video1" -o "./output_http.so -w ./www -p 8081" -b

4: put HTML file /www/webcam/doubleview.html

<html>
  <body>
<script language="JavaScript">
document.write('<img src="' + window.location.protocol + '//' + window.location.hostname + ':8080/?action=stream" width="320" height="240">' );
</script>
<script language="JavaScript">
document.write('<img src="' + window.location.protocol + '//' + window.location.hostname + ':8081/?action=stream" width="320" height="240">' );
</script>
  </body>
</html>

5: Open http://[ OmegaIP ]/webcam/doubleview.html .

Open "Authenticator" page,
press Ctrl+Shift+i,
select "Console" tab,
put below code.

$("i.pficon-delete").addClass("glyphicon glyphicon-remove");

You can find "X" mark. It can delete TFA.

@Damien I checked your omega.txt.
Your Omega already detected something on boot-time.

Did you connected USB-hub before boot?

Your MCP4131 are bit careful for use with SPI.

3.3 Serial Data In / Serial Data Out (SDI/SDO)
On the MCP41X1 devices, pin-out limitations do not allow for individual SDI and SDO pins. On these devices, the SDI and SDO pins are multiplexed.
The MCP41X1 serial interface knows when the pin needs to change from being an input (SDI) to being an output (SDO). The Host Controller’s SDO pin must be properly protected from a drive conflict.

Please check datasheet page 41. You can see the "Typical MCP41X1 SPI Interface Connections (Host Controller Hardware SPI) " wireing.

@Ken-Conrad It is Japanese maker ELECOM's UCAM-DLY300TA .
