Hadn't thought of that, no tally for that on a log. K-360 but caps lock 
doesn't enable/disable that indicator. AIUI, that keystroke goes to the 
computer, and the led on off comes back. So my assumption is that usb is 
disabled when blanked. But since I have the blinking underline cursor, I 
wouldn't call it blanked either. But since its only happened twice, and 
I finally got twm to run the windows instead of lightdm running xfce4, 
it may not happen again.

My usb dongles are on the end of an extention cable, within a 10cm  of 
both the keyboard and the mouse, Poor pointer control is not a problem. 
Keeping batteries in the mouse is. And getting ancient fingers to hit 
the correct keys is the biggest problem by far. :)

I do use a lot of usb here but thats the extent of usb+wireless. I even 
have all the radios turned off due to a neighbor's cell phone that can 
hack into an active radio and use 80gb of my bandwidth a month, and do 
it 2 seconds after I enable the radio, but I do enable the radios so my 
visiting boys can use their $800 cell phones while visiting.
