ideapad c340 support for USB 2.0 backwards compatibili

2020-01-30, 20:03 PM

Hey,

 

I have a sound card that is, unfortunately, not working well on my new Ideapad c340.

 

I read on the manual of my sound card that its connection must be a USB 2.0 port or a USB 3.0 port with backward compatibility.

I have switched the connection of the sound card to a different usb on the Ideapad ( the first I tried was apparently the " Always On USB" )

after switching I have been able to hear the sound without any problems.

 

I would like to know if he 3.2 has  USB 2.0  backward compatibility.

 

What would you recommend me to do in order to continue using my sound card if the usb on my new computer is no backward compatibility?

 

 

Thank you.

jeki.

Hi jeki,

 

Welcome to the Community Forums.

 

I would like to clarify if you are trying to use and external sound card on the USB ports.

 

I would also like to clarify that USB 3.0 is automatically backward compatible with USB 2.0.

Hope this helps,
Jack_Lenovo1

Hey Jack,

 

Thank you for your replay.

 

I am happy to hear that a USB 3.0 is automatically backward compatible with USB 2.0.

 

Yes, I am connecting an external sound card on the USB ports.

 

I experienced many short dropouts in sound while working with my DAW software.

As I mentioned, to my relief, this situation had changed when I swiched to the other usb connection on the device,

though I am wondering why does it matter if it should be that both of them are compatible with USB 2.

 

I hope this situation will not return, I only got the chance to teste it for a short while but the difference between usb sockets was immediately noticeable.

 

Best regards

Jeki.
