Since I saw nothing on the sites selling the Griffin Firewire to USB converter in regard to how it worked, or didn't work, with the CD-IB100II, and since the other converter on the market did disclose that it did not work with the CD-IB100II, I ordered the Griffin converter. When I finally got it and tried it, it did not appear to charge my 4th generation iPod Nano. So I finally went to the Griffin support site, which I guess I should have done before, and found that the converter DOES NOT WORK with the CD-IB100II. Thanks again, Pioneer (for nothing).
