Hello, It wouldn't hurt getting a couple of those ferrite chokes and putting them on the lines. If on a power line put it on the cord as close as possible to the power source. You may have noticed that the more expensive USB cables, audio lease and power supplies will have a ferrite choke on them. I had a buzz with my AllStar MicroHub. I had a ferrite choke that I think was on a Decktalk Express serial cable. So I opened it out and wrapped the cable about 2 turns and closed it back together. Because the thin wire wasn't gripped I didn't think it would work. But it did very well. Very useful to have some kickingarond. Be careful though, I just brought some and they are not hinged.
