Idock c20 - headphone jack gives usb resources exceeded error

Support
1

I have an idock C20 connected between a Dell laptop and a new Lenovo IdeaPad Pro 5. When I try to test the headphone jack on the idock from the IdeaPad, I get a message saying my USB resources are exceeded.

I have a keyboard, a mouse, and a webcam, and the two monitors connected so it’s not like I have a lot of stuff attached.

It was working until I switched the usb ports for the keyboard and mouse from the back to the front as I was clearing up my cables.

Anyone have any thoughts as to what might fix this? I tried the usual troubleshooting and the Windows 11 page on these errors but I can’t see anything that might cause this.

Hi Michael,
Thanks for getting back to us and sorry for that.

  1. You mean it is working fine until you try switched the USB keyboard and mouse to the front usb ports,right?
  2. Have you tried unplug and replug in the USB-C cable from the IdeaPad to the iDock C20, or tried reboot the ideaPad for a check?
  3. How about try switch the keyboard and mouse to the rear USB port at iDock C20?
    Best Regards,

  1. Yes, that is correct. only when the keyboard and mouse is plugged in the front do I get the usb resources exceeded error. When I returned them to the back, it works
  2. Yes, no changes
  3. Yes, and it works again.

I was trying to clear up some cables and free up a port in the back but it’s workable as is.

Is there a difference in the front USB ports vs the back ones?

Hi,

The front USB port is USB 2.0, and the rear USB port come have 2x USB 3.0 and2x USb 2.0, so you can check if they only work at the USB 3.0 ports?
By the way, maybe you can try use a USB-C to USB-A adapter to make they connect to the front USB-C port to have a test.
