Does Lenovo IdeaPad 520 (15IKB) really have two USB 3.0 ports?

According the official technical specifications on Lenovo's website, the IdeaPad 520 (15IKB) notebook has two USB 3.0 ports and one type-C port. But on my IP 520, the two USB-A ports don't have the expected blue colour coding for USB 3.0 and also they both don't have the (SuperSpeed) SS-USB symbol. Instead they have the regular USB trident symbol. Only the type-C port has the SS-USB symbol.

 

The Windows Device Manager lists three USB related drivers viz.

  1. Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)
  2. USB Composite Device
  3. USB Root Hub (USB 3.0)

 

So, the IP 520 really does have two USB 3.0 ports or it's a gimmick?

Hi Deepak_HK,

 

Greetings.

 

The Ideapad 520 15IKB have three 3.0 USB ports.

Two type A USB port with 3.0 speed and one type C with USB 3.1 Gen1 support as shown from the user manual.

As with newer laptop (even from different OEM) USB 3.0 blue code standard is not mandatory.

With current technology, lower version (1.0 , 2.0) are backward compatible to a 3.0 USB port so device manager would be expected to have "Universal Host" and "Enhanced Host" "USB 3.0" drivers.

 

Same goes on the product specifications sheet and hardware manual page 26

Plugging a 3.0 device on test machines would allow to electrically check the dedicated pins internally.

 

Hope this helps answer your query.

 

Regards

Thanks for the support. So, those three USB drivers I had mentioned earlier are enough and the expected ones or these two drivers are missing?

 

My laptop's Device Manager lists these three, and only, USB drivers:

  1. Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)
  2. USB Composite Device
  3. USB Root Hub (USB 3.0)

Thanks.

Hi Deepak_HK,

 

Those three physical ports are all expected to provide 3.0 connection speed.

Each would have backward compatibility for lower versions with corresponding drivers.
