USB 3 disk seen as a usb 2 disk ?

[huotg01]

What is the best (simplest) way to make sure that my USB3 disk is really seen as a usb 3 disk by my RT-AC68U, and that it works at the usb 3 speed ?

Thanks

Enter the following.....

nvram show | grep _speed

This will show the attachment speed for the usb drives....480 for USB2 or 5000 for USB3.

Thanks. Here is the answer:

size: 42760 bytes (22776 left)
usb_path1_speed=480

Does that mean that my usb 3 is seen and processed as a usb2 ? If yes, does something can be done to correct the situation ?
Thanks.

This worked for me

I had the same problem with my usb3 being seen as usb2. It turns out that I had formatted the drive on my iMac which only has USB2 ports. Somehow, it turned the drive into a usb2 drive. I then formatted the same drive using my PC with USB3 ports. I then connected to the router and surprised! It now saw it as a usb3 drive. I don't know why this is so, but it worked for me.

Ok, I found out how to disable the "Reducing USB 3.0 interference" switch in Wireless/Professional. Now here is what I have. Seems ok.

Beat me to my reply You've got it!

For future reference, the other thing to try is a different USB3 cable....some that are shipped with the drives are 'less than good' quality.
