Unusual Card Reader Behaviour.

Linux Support
1

I don’t know how in hell it’s happened but my SD card reader doesn’t seem to work right with my laptop.

As I plug it in, the red light comes on for power, but the green light which indicates when a memory has been put in, comes on when there’s no card in it. Yet if I plug it into my PS3 it doesn’t do it? I don’t understand what’s happening and if at all possible, please help. >.<

EDIT: Ok now it’s not doing it. Seems to be some issue with the USB cable. :S I changed it from the PS3 cable to my digital camera cable.

Have you tried it in different USB ports ?

is it a USB card reader ?

Have you tried having the card/reader inserted when you turn the PC on?

if you pug it in whilst the PC is booted, then just after plugging it in, run

dmesg | tail -n 20

are there any clues ?

Read my edit. Seems to be the USB cable.

Just for safety’s sake…
