From the shell/commandline, you can determine the capabilities of your USB webcam quite simple (works for most, but not for all webcams).

$ lsusb
Bus 001 Device 002: ID 5986:0241 Acer, Inc BisonCam, NB Pro

This lists all USB devices. Find your webcam and write down BUS (001) and DEVICE (002) number.

We will use them in this statement:

lsusb -s 001:002 -v 

This statement will show ALL details of your webcam/USB device which can be overwhelming. If you're only interested in video modes, try:

lsusb -s 001:002 -v | egrep "Width|Height"
    wWidth 640
    wHeight 480
    wWidth 1280
    wHeight 1024
