For an integration we are doing here I have needed to add the following device to use the usbserial driver. It is a Novatel OEM GPS receiver card that has on-board USB-serial capability and it works well with the default usbserial driver. The dmesg output mentioned I should forward the particulars of this device to this email address. I have also included the pertinent lsusb and dmesg output.
