Officially there are no specific drivers for US-122 for windows 7. In case you have an error I suggest you to download the winXP
v.3.40 from this link,
unzip the files from the downloaded one, right click on the file US122_Win_3.40f.exe, choose properties, go at the compatibility tab and check compatibility with Windows XP sp3 and click apply - ok. After this install the drivers with double click on this file and check the results.
