Hi When I connect my “WD my passport” external hdd to usb2 port, it dos’t work and show “USB Device not recognized” erorr . but in USB3 port, show thats Erorr but I can open it and see my File!!!
That is very strange, however let’s try to fix the problem. Would you try to go to the manufacturer’s website of the computer, look for Support/Drivers and enter your model number. After that look for a download(s) and download a “Chipset” or “USB” driver package, and install that. Reboot and see if the issue persists. If it does, it may be a problem with the computer itself and you should contact the manufacturer if it is still under warranty.
