This config is available from Image Version 0.1Beta 9 and onwards. The power enable pin settings can only be done on a global level. As the loading order of the USB host ports can change we have to define the keys in all of the USB host configs (USBEHCI1, USBEHCI2, USBEHCI3).
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USBEHCI(1/2/3)] "SodimmPen"=dword:0x00000081 ;Power enable SODIMM pin, defaul pin is SODIMM Pin 129. "PenPol"=dword:0x00000000 ;Power enable polarity, default 0 (Low Active)
Some USB devices are not recognized when they are plugged in during runtime. Sometimes it helps to increase the delay between plugin and setting up communication pipe by adding the key HotPlugDelayMS. Add the key to the required USBEHCI device (1/2/3). A typical delay of 100 ms is required for some USB devices. This feature is supported since image 1.3 beta 3.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\USBEHCI(1/2/3)] "HotPlugDelayMS"=dword:0 ;Delay between plugin in the device and opening communication pipe in MS, default 0 ms.
