    Should I be able to mount usb2 hard drive in usb3 port?


    Tried to mount a usb2 hard drive in a usb3 port just now with no joy. Not positive, but I think I've done this before. Running version 20H2 and there was a recent update. My laptop also has a usb2 port but it's in an inconvenient location.

    Should usb2 drive in usb3 port be working? If so, can I fix it? TIA

    Yes, USB 3 is backward compatible with USB 2

    I hate to have to revive this thread (thought it was solved) but no...

    I have several usb hard drives (all WD Elements 2TB) two of which are usb 2 and two usb 3. The usb 2 drives will NOT mount in the usb 3 port on my computer. The computer does have a usb 2 port (around back where it's hard to reach) so I can use them as needed but these drives SHOULD work in any port.

    If anyone can suggest a solution, step right up! Running Windows 10 20H2. TIA

    Do you have latest chipset drivers for your laptop installed? downloaded from Dell site?

    Please fill in computer specs:

    Sorry, not to be uncooperative, but I've looked through both manuals for my machine and can't find most of the info needed to fill in that form. As I mentioned earlier, I had an update one day last week and I seem to remember having plugged in the usb 2 drives at some point prior to the update but can't remember for sure.

    I may have a usb extension cable around somewhere that I can use in the usb port on the back of the machine to make it more accessible but this should really not be necessary - I have another machine running Ubuntu Linux that accepts these drives with no trouble at all.

    system info.zip OK - sorry for the delay.

    - - - Updated - - -

    I checked the Dell site and installed two upgrades (marked urgent). My mounting problem is solved. Thanks for your help.

    - - - Updated - - -

    After closing this thread (believing it to be solved) the problem of usb2 hard drive not mounting returned. In desperation, I tried switching the cable connector from one of the usb3 drives to the failing usb2 drive - which immediately worked. I have replacement cables for all my usb hard drives on order...

    That while USB is backwards compatible, the speeds will only run at the slowest speed of the device in the chain. That also includes the cable.

    EX - USB 3 device, USB 3.0 cable, USB 3.0 hub, USB 3 connection point = USB 3.0 speeds. On the other hand USB 3 device, USB 3.0 cable, USB 2.0 hub, USB 3 connection point = USB 2.0 speeds. Or USB 3 device, USB 2.0 cable, USB 3.0 hub, USB 3 connection point = USB 2.0 speeds.

    That's the starting point, but there are also other factors that can influence speeds as well. But for your simple question, yes, as zebal noted, you'll just be limited to 2.0 speeds off the bat.
