Now I understand your question. blush

A good powered hub might make the difference if the issue was caused by the keyboard receiving marginal to inadequate power from the USB port on your iMac, or if it is a static electric issue the powered hub would provide additional grounding protection.

On the other hand Macally has a good reputation, but I have not had any recent personal experience with the brand.

Since this issue is occurring both with and without a powered hub, in your position I would return the keyboard for replacement. (Actually that is not completely accurate. I would return the wired keyboard for one of Matias' full size wireless keyboards because I like the one I have so much. grin )
