Hi, As you can see from the dmesg output.. this device is not being detected as a USB communications device.. ugen(4) is the USB generic device, a catch-all driver as you will.
Please update to a supported release of OpenBSD, that will be 4.4 and 4.5 come May 1st.. currently it's 4.3 and 4.4. Have fun, +1 Marco's suggestion as well. -Brynet
