New Revision: 48719
URL: http://svn.reactos.org/svn/reactos?rev=48719&view=rev
Log:
[usb/usbhub]
- Add function for dumping the Device and Configuration Descriptors.
- Implement WaitForUsbDeviceArrivalNotification, used to send a URB transaction to the
Status Change Endpoint of the RootHubs pdo. The RootHubs pdo will queue this request until
a new usb device connects.
- Call above function at the end of UsbhubFdoQueryBusRelations, which will be called by
the pnp manager after the hub driver creates a new child device.
- Change the URB to be allocated from the pool at IRP_MN_START_DEVICE.
- Call QueryRootHub with the RootHub Pdo and not the hub drivers DeviceObject.
- Implement selecting a configuration for the RootHub.
