Hi all,

I am using Macbook pro with Belkin USB-C dock. I use it for several months without any issue.

But recently it shows some drivers can not be loaded successfully due to unsufficient PCIe resource.

I tried to debug it and I found it only happen if I connect Pegasus 3 before this Belkin dock.

Even though I already remove the Pegasus3 device, it still can not load Belkin dock driver successfully.

I have to reboot it and everything shows okay. So I think the Pegasus3 driver is not unloaded when it is removed.

Can it be fixed?

Hi Yves,

Have you tried reinstalling the drivers to see how it works. Click the below link to download the drivers.

Hi Pradeep C,

The driver package is the same as I used.

One more information. If I don't launch Pegasus Utility, this issue will not happen.

So it seems Pegasus utility will keep driver from unload after unplug.
