The external esata port multiplier I just received today would cause my system to crash whenever it was connected. I remember having the same system crash experience back when I wanted a USB hub, and bought one. Whenever I plugged in the power supply, my whole system would crash.
That's what I experienced today. Same style power supply, same crash. I also have an El Gato eyeTV that uses a similar style power supply, but it is white and nicer looking. Same specs, so I figured what the heck and decided to try it out. It worked. The port multiplier is now working with the Sonnet E4P without crashing. Problem sort of solved. Now I need to get power supplies that have minimum leakage so that the USB hub, the esata port multiplier and my eyeTV will all work. If any of you have ever bopught one of those elcheapo 7 port powered usb hubs and had problems with it like me, could by high leakage on the supply. Oh and I also have all my computers and peripherals on APC backups.
