Hi. I have a smart media card reader "Sanisk ImageMate". When i first connected it to my pc the install wizard was able to detect it so it installed the driver from the disk. when i inserted the smartmedia card, nothing happened. the only visible light is on the left side of the card reader which i believe is for "power" and the other led on the right side is not lit, which i believe should blink as if it's reading the card but it does not light. and when i open my explorer the "extra" drive for this device is not shown. is there a problem with the card reader? please help, i appreciate it.
