All of a sudden my notebook isn't been able to read any memmorycard anymore. When i look under devices i see a warning sign, unknow device. I tried to reinstall the drivers (SP47066), the setups says that everything is installed succusfully but still the cardreader isn't working. Also rebooting doesn't work.
The fault occured while using the cardreader
ps: my notebook is: HP probook 4520s and is still under warrenty
