The problem ports/controller are my USB3 ports and the older USB2 ports work fine.

I've noticed that USB3 ports are a pain, I have a few on my PC and I find it can take 20 seconds before it recognises a device has been plugged in, yet other true USB3 devices connect instantly. I just avoid using them if I have a USB2 device.

Also, after updating my firmware to the latest .40, I clicked the Refresh button and fields stayed blank.

I found that yesterday as well and let Paul know.
