I have Asus BE24a monitor connected via DisplayPort to Nvidia Quadro K2000.
The monitor has built-in line-in input, loudspeakers and 2 USB ports. The loudspeakers are detected by Ubuntu as output devices and I can stream audio there without a problem. According to the manual, built-in USB ports may be used as regular USB port to plug in auxiliary devices like card-readers, web cams etc.
I have HP 4310 webcam, which I'd like to be connected to one of the USB ports on the monitor. However, when I do, the webcam is not detected by the system.
However, the webcam can be detected normally when plugged in directly into the workstation. It seems not a driver problem, but Ubuntu not seeing webcam through the monitor.
I tried lsusb and lspci to no effect

I tried lsinput, which did not give anything related specifically to the webcam. Just some GPU related entries, like the one below
/dev/input/event14
bustype : (null)
vendor : 0x0
product : 0x0
version : 0
name : "HDA NVidia HDMI/DP,pcm=9"
phys : "ALSA"
bits ev : (null) (null)
I did not find any relevant info how to use display as a hub in Ubuntu and any such issues either.
Anybody knows how I could make my webcam be detected through display? What else to try?
Thanks in advance.
