I was backing up my Sam440ep last night to do a fresh reinstall to see if that helped with my USB mouse and keyboard ceasing to work every few minutes. I realised and found the following:Spectre660 wrote:My first problem after rebooting with update 3 was no working keyboard or mouse. They were both connected to a hub so looks like Hub support is indeed broken.
* My mouse was going through a powered USB hub. Once I plugged it directly into the back of the Sam440ep it kept working and never stopped working again.
* My Keyboard is plugged directly into the Sam440ep BUT it keeps dieing, needing to be unplugged and plugged back in again to get it working for a few minutes. With that said, the Keyboard itself contains a USB hub in it which worked perfectly will with Update 2 and earlier.
So from what other people have postulated in this thread, having a USB hub in the equation does seem to cause a problem.
I have not attempted to disable EHCI at this point in time yet. I will try that out when I get home from work tonight and see if that helps me or not.
