Hi, thank you for your help. Sorry for not anwsering for so long. Well,
the same disk worked in the same laptop, in the same drawer, with same
windows :( I also tried to remove/reinstall the drivers, with no help..
he does actually show him in system tab, under "Unknown usb device...".
I've flashed the lap with newest bios version..

Ty,
