New Revision: 51325
URL: http://svn.reactos.org/svn/reactos?rev=51325&view=rev
Log:
[USB\USBEHCI]
- Fix linking of QueueHeads. Implement LinkQueueHeadToCompletedList and CleanupAsyncList. These functions are used to software link the completed queueheads to a completed list. Only after the driver handshakes with the controller can this memory be freed.
Fix a few incorrect values for QueueHead.
- EhciDefferedRoutine: Implement handling of completed QueueHeads by removing them from the AnsycList and setting any errors for failure.
- Reserved a QueueHead that will always be in the AsyncList Address Register. By setting it as the Head of Reclamation the controller can know when it has reached the end of the QueueHead list.
- Remove all code from FdoDispatchInternalDeviceControl. This should never be called by upper level drivers.
Change 1 of 3.
