True. Those files are mainly placeholders, waiting for usbfs2 to be developed. > Shouldn't I see a /dev/ttyUSB2 created since there are already 2 > pl2303 cable's there now?

It's the same situation here -- the UPS registers itself as an HID device, not as a serial device. > Greg K-H:Can you provide the output of /proc/bus/usb/devices?
