Lol, two observations here from my experience:
1. When I mentioned earlier that I had used an existing USB-to-USB_mini cable to sync my Reader, it turns out that that cable is used by my PS3 to charge its wireless controller. After reading about the said lump in question, I went back and checked that cable; turns out that it has one too! I had no problem syncing with that cable and it appeared to charge, though I can't be sure as I had to charge it again about a week later (been doing a ton of fiddling with it and such).
2. A few years ago I purchased an external DVD/CD-writer for my TabletPC, I had picked up a Sony since it also could double as a portable CP/MP3 player (had a RioVolt prior to the whole iPod movement) and felt it could do double-duty. Waste of cash, as I never really used it due to my preference for daemon tools. Anyway... the Sony portable actually came with about 6 ferrite dohickies to snap onto the USB cable to "reduce interferrence."
So that being said, I think Sony is a firm believer that it's products are highly succeptible to some type of interferrance so it provides some type of magic bean to mitigate this issue. Perhaps an EE person with some experience in this phenomenon can enlighten us to the theory/reality of this head-scratcher? Thanks for listening!
