I am using nec versa p520. I am not able to detect any external storage devices connected to my laptop. As such they are auto detecting in other systems. Could any one give me a solution
I didn’t meet a problem using external USB and IEEE 1394 devices with NEC Versa notebooks. I had two Versa P4 1.8 notebooks. Both were probably P520, not sure since neither stay with me anymore. Try each device step by step. Don’t you use a USB mouse or keyboard for the laptop? External USB HDDs and ODDs are just IDE devices added to USB interface.
Check the BIOS, then the Device Manager. And finally any Windows updates for USB.
