Hi Vintage Your quote : Ok, next question, I need the power supply specs for the Power Sentry USB hub. I opened it up to try to determine what it wants but am not savvy enough I guess. It has a 278R05 voltage regulator on it (listed here: http://www.lekwong.com/product_infor.htm#ic04 but no specs) but I have no data for it. What was your finding at the time for actual voltage of Power Sentry Hub a long long time ago? I have currenlty exact same question. I would appreciate answer. Thank you very much uin advance
