Permissions to access USB camera under debian

[Micha Feigin]

Doesn't seem to be a camera group (there is a camera user, which may 
affect that), no v4l and video under the dev tree.
Only thing I found that changes under dev during connection is these two 
files:

lrwxrwxrwx 1 root root 18 Jul  2 13:35 /dev/char/189:389 -> 
../bus/usb/004/006
crw-rw-r-T 1 root root 189, 389 Jul  2 13:35 /dev/bus/usb/004/006

So I don't think that it shows up as a camera but rather as a USB device 
(which makes sense as it's a depth camera that returns three images per 
frame with some extra related parameters, not a regular camera)
Looks like I need to change something in the system setup to change the 
default group or something similar

Device shows up as this:
1865748.404803] usb 4-2: new high-speed USB device number 6 using ehci-pci
[1865748.537404] usb 4-2: New USB device found, idVendor=1ad2, 
idProduct=0075
[1865748.537410] usb 4-2: New USB device strings: Mfr=1, Product=2, 
SerialNumber=0
[1865748.537413] usb 4-2: Product: 3D-SR4000
[1865748.537417] usb 4-2: Manufacturer: MESA

Thanks
