Please check PWR signal. Maybe MOSFET is enable to early. Might it be a solution to add a configurable delay (via registry) before enabling power, to make sure that system utilization is ok? Check USB driver priority? |

Enabling USB power after host controller has been initialized seems to resolv this issue already. But during testing I have noticed that PowerUp functions are not called. Maybe these functions are the correct location for enabling/disabling USB power instead of doing this in Init() function. |
