I am pretty sure you will find that the usb drivers get installed as part of the Zune software install. The software itself is available for download free from MS. You are not required to open a Zune account.
you can't connect the new kin onem/twom as usb to the computer. none of the system will recognize it.
you HAVE to have ZUNE SOFTWARE installed then connect them to your computer to sync media files only (videos, music, podcasts, photos) using Zune--kind of like iTunes to iPhones.
if you have a mac, i heard zune is releasing mac version soon, or try this: http://www.markspace.com/kin/
Yes, once I installed the zune software it works just fine. Thanks.
