However, it doesn't show any /dev/ttyUSB*. I'm not sure what I have missing here.

There is 500 seconds between these two lines, I'm not sure if they are really related: [72169.554498] hid-generic 0003:0665:5161.000D: hiddev0,hidraw7: USB HID v1.00 Device [INNO TECH USB to Serial] on usb-0000:00:1d.0-1.6/input0 [72685.019094] usbcore: registered new interface driver usbserial. The first part suggests the UPS acts like a input device (maybe a power button?) –  Jakob Aug 20 '13 at 7:00
    
did you look for new device files with other names? –  jP_wanN Aug 20 '13 at 7:59
    
Jakob I don't think so. @jP_wannN what is your suggestion that I should try? –  scalopus Aug 20 '13 at 13:29
