Hi, I know that this is not a very helpful information. I have an Lenovo X220 running 10 from some 2 weeks ago. I just noticed that the USB mouse (a wireless Logitech Trackman) becomes unusable when the wireless (iwn) is not able to connect to the access point and a USB hard disk is plugged in. Even when no data are transferred the USB mouse is unusable. The built-in track-point behaves just normal. When I turn off the wireless network via the hardware switch, the system stays usable as expected even under heavy hard disk access. If it was not something else I have missed, the only difference was the access point which went down when I noticed the problem. Please understand this just as a hint to the developers of the sub-systems which could cause the problem. As this network here is not mine, I am not able to do any tests with it. If somebody has an idea what could be tested, tell me please. I will have access to 'my' network the coming week again. Erich
