- Create a branch to do a proper merge of USB work from a trunk base instead of from cmake-bringup - In the future, DO NOT under any circumstances branch another branch. This leads to merge problems! svn path=/branches/usb-bringup-trunk/; revision=55018

25 May 2008 - Created

|
Notes:
|
|
This uses some obsolete calls (eg: HalGetInterruptVector).
|
|
Might be worth updating this in future to use some of the
|
|
recommended functions like IoReportDetectedDevice and
|
|
IoReportResourceForDetection...
