Thanks for responding, Martin Gregorie & Dan Kegel! Went to that Ubuntu link & decided to run <dmesg> from a console & this came up: usbcore: registered new interface driver usbserial USB Serial support registered for generic usbcore: registered new interface driver usbserial_generic usbserial: USB Serial Driver core USB Serial support registered for PocketPC PDA ipaq 2-2:1.0: PocketPC PDA converter detected usb 2-2: PocketPC PDA converter now attached to ttyUSB0 usbcore: registered new interface driver ipaq ipaq: v0.5:USB PocketPC PDA driver usb 2-2: USB disconnect, address 2 ipaq ttyUSB0: PocketPC PDA converter now disconnected from ttyUSB0 ipaq 2-2:1.0: device disconnected usb 2-1: new full speed USB device using uhci_hcd and address 3 ipaq 2-1:1.0: PocketPC PDA converter detected usb 2-1: PocketPC PDA converter now attached to ttyUSB0 usb 2-1: USB disconnect, address 3 ipaq ttyUSB0: PocketPC PDA converter now disconnected from ttyUSB0 ipaq 2-1:1.0: device disconnected usb 2-1: new full speed USB device using uhci_hcd and address 4 ipaq 2-1:1.0: PocketPC PDA converter detected usb 2-1: PocketPC PDA converter now attached to ttyUSB0 usb 2-1: USB disconnect, address 4 ipaq ttyUSB0: PocketPC PDA converter now disconnected from ttyUSB0 ipaq 2-1:1.0: device disconnected usb 2-1: new full speed USB device using uhci_hcd and address 5 ipaq 2-1:1.0: PocketPC PDA converter detected usb 2-1: PocketPC PDA converter now attached to ttyUSB0 So, it recognized, somehow, the device.
