Y410p USB 3 port randomly dropping USB 2 devices

[abradner]

Hi guys,

I'm having an odd experience with my 410p where my USB 3 port will drop and reconnect my USB 2 devices (I believe the USB 3 devices stay connected, but they all have their own power supply so it's hard to tell). Using the USB 2 ports on the right has no problems

It only happens for a fraction of a second, but that's enough to freak out my USB sound card, keyboard and mouse. This occurs through two separate hubs (one usb2, one hybrid 2/3), and directly connecting the devices.

I am running windows 7 x64 with the latest usb drivers from intel (as of last week), although this problem also manifested in windows 8 and 8.1

I realise what I have said is a little vague, and I'll try and narrow it down a bit further, but has anyone else experienced anything like this, or know of any solution?

Cheers

I had a similar issue. Unfortunately, you will probably have to restore windows to factory settings. Best of luck!

That's strange... Just out of curiosity what what device is dropping out? Could it be the other end of the cable?

Have you tried USB 3.0 driver from Lenovo website? It solved my odd problem with my USB 3.0 port. I wish you luck.

On my last Y570 both of USB 3.0 ports dont work. Lenovo service replaced motherboard, because she was defective.
