i run windows 8 on toshiba satellite C855D-S5232 laptop
howevr long i cnnsct the reader to te usb port [all 3 ports are of usb2
even after the red light goes off i disconnect usb device then only 3 black squares are filled one remains white.
if i connect it back to usb port again red light comes on and in 15 20 miutes
light goes off
then if check the reader shows all 4 black squares.
once red light goes off means it is charged fully is it not.
and when i am in my gentoo linux boot the reader does not charge at all
all file operations work fine
there is no mains charger supplied with this reader and i cannot find one by any search.
i have many 5.2 VDC mains adapters but no connector matches with the reader power DC connector

any suggestions for me?
the battery seems to be ok. still i get 12 15 rs continuous reading before one black square becomes white
