I guess what surprises me is that the device hears about it. I would have expected a mouse to be an input-only device, with the kernel just doing nothing with the incoming samples if nobody is interested. I suppose I'm not familiar enough with USB. (But, the more I learn about USB, the less I want to learn more....) In any case, thanks for explaining! > All modern USB mice I have do this.

My impression was that the disconnect/reconnect was random, but I could have just not been paying enough attention. > There is a second kind of breakage affecting mice that you did use > for some time already and where the cable becomes bad at the entry > into the mouse housing (probably due to bending during movements). > This makes power for the chip inside the mouse flaky and it randomly > disconnects. Thanks again. I'll keep that in mind in case the timing looks too random to be the other syndrome. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
