OK - I tried everybody's various tests.  Following are the results.

bob@linuxmint ~ $ ls /dev/usb*
/dev/usbmon0 /dev/usbmon2 /dev/usbmon4 /dev/usbmon6 /dev/usbmon8
/dev/usbmon1 /dev/usbmon3 /dev/usbmon5 /dev/usbmon7
bob@linuxmint ~ $ =20


bob@linuxmint ~ $ ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1
bob@linuxmint ~ $ =20

bob@linuxmint ~ $ ls /dev/*USB*
/dev/ttyUSB0 /dev/ttyUSB1
bob@linuxmint ~ $

bob@linuxmint ~ $ ls /dev/ | grep usb
usbmon0
usbmon1
usbmon2
usbmon3
usbmon4
usbmon5
usbmon6
usbmon7
usbmon8
bob@linuxmint

It was not necessary to go to root to display the USB ports.  I am =
currently using WinSDR on Windows XP through a USB port so I know the =
RS-232 to USB connector is working.

One other thing you may need to run as root to get a listing so try:
