Question 1

This needs a single USB Header input and connection to the power supply? Or does it need a USB 3.0 Header AND a USB 2.0 header for 3 ports and a card reader?

Accepted Answer

I believe I will answer this correctly even though I do not know proper names. it has either a sata power or molex power (your choice). and it comes with a USB 3.0 cable to 19 pin header and USB 3.0 to standard USB 3.0 blue port (or SS super speed) which can be used to say push out of case and attach to an available USB 3.0 port. the box says it has a USB 3.0 A-B cable and a USB 3.0 header to B cable. so guessing here I believe when I said USB 3.0 the technical equivalent is USB 3.0 B cable I think. but from what I think u asked. it only needs one of the two provided cables and a sata or Molex power. I connected mine to a syba 2-port USB3.0 card that happened to have a 19pin header. the only thing I didn't like was I had to power both card & front hub. you have to disassemble (easy to open) to connect USB cable & power. mine didn't work at first because I didn't see u needed power but upon reopening I realized my error. hope this helps

Question 2

Is this compatible with Linux?

Accepted Answer

I run Windows 7 Ultimate, but I don't see why it wouldn't work with Linux.

Question 3

I cannot format or write to any card in this reader.  My cards are acting like they are write protected. This is in a windows 7 machine.  Any ideas?  Thank you.
