Thanks for the help and insights, gents. I have always left my headset plugged in also. In the short term, I’ll give a powered USB hub a try. Then, look at a 3.1 upgrade internally. I’ve not changed any hardware configuration. That’s why this has mystified me and made me wonder if an update caused this to start happening on a very random basis.
Thinking more about my random occurrences, they’ve only happened in the training arena while working with one other player, never in any other arena. Coincidence?
Anyhow, thanks for ideas, gents.
