I know nothing of this subject. So, if you're asking if I modified a 
rule list - definitely not.

I searched the linux websites to learn about it (tldp and LQ); I found 
some info (but didn't read it yet). Here is the pertinent section (I 
think) of my /etc/udev/rules.d/50-udev.rules:

# usb devices
KERNEL=="usb/dabusb*",          MODE="0660"
KERNEL=="usb/mdc800*",          MODE="0660"
KERNEL=="usb/rio500",           MODE="0660"
