USB Input not working and the Screen is scrolling white lines

Just purchased this DAC and upon hooking it up have been unable to get the USB input to work. The control panel shows the DS as the speaker selected. Also the display has a continuous scrolling of white lines in the background when the display is on. Anyone else have these problems?

OK, reinstalled the USB driver the second time and it is now working. Another question, on the download page, I see there are 2 USB drivers. What is the difference in them?

Yes, this is a known flaw.
