- Missed a fix from last commit
- Wait for the device status change work item to complete
- The USB stack is now properly constructed for USB booting
svn path=/branches/usb-bringup-trunk/; revision=55339
- Save PortNumber in child device extensions as its needed when PNP request device capabilities.
- Handle IOCTL_INTERNAL_USB_SUBMIT_URB request by creating a new Irp and passing the Urb down to the miniport.
- Now working with our ehci driver, we at least see a usb driver and can browse directory in Windows, though doing so results in assert as ehci doesnt support transfers over 5 Pages yet. Fix coming soon.

- Implement constructing CompatibleIds string using device descriptor. However, if the Class of the device descriptor is 0, then Class, SubClass and Prot which make up this string must come from the Interface.
- Change Ids and Descriptions to Unicode Strings.
- Move the creating of Id strings to one place, CreateDeviceIds, and called it at device creation.

- The lower level driver completes the SCE IRP whenever the change state has been modified for a port. When handling the SCE IRP completion only check for flags in change state. The Change flags must be cleared else the hub driver will get non stop SCE IRP completions.
- Allocate IRP from Pool vice calling IoAllocateIrp. Dont free the IRP in the completion routine as the port driver, oddly, frees them.
- GetUsbDeviceDescriptor: Remove use of MDL and use only buffer instead to make our new usbehci happy.
- When calling the interface routines, correctly use the BusContext returned from the interface instead of the RootHubPdo. This worked on windows as it just happened they were the same.
- Implement RootHubInitCallbackFunction, which only job currently is to send the first SCE IRP.
- For Start Device for child device objects fake success for now. Will be implemented later.
- Implement returning IRP_MN_QUERY_IDs, IRP_MN_QUERY_DEVICE_TEXTs and IRP_MN_QUERY_BUS_INFORMATION.
- Add basic handling for IRP_MJ_POWER.
- Misc code changes.
svn path=/branches/usb-bringup/; revision=51620
- Add UsbDeviceHandle to child device extensions structure to be passed with URB requests.
- Reimplement the Worker Thread DeviceStatusChangeThread called on SCE completion. Each SetFeature and ClearFeature resend SCE request.
Only create the usb child device if the PortStatusChange member of the device extensions was modified.
- Implement CreateUsbChildDeviceObject used for creating a deviceobject for the USB device and initializing it.
- Implement GetUsbStringDescriptor for getting DeviceId, TextDescription and InstanceId from USB Device.
- Move the initial QueryStatusChangeEndpoint to after the hub device receives start pnp.
- USBHUB driver is now back to the same functionality of previous version. Showing the device wizard for connected devices.
svn path=/branches/usb-bringup/; revision=51581
- Change parameter name for DeviceObject in functions to clearify which device object is to received IRPs.
- Fix a typo in GetPortStatusAndChange that caused the function to return nothing for status and change.
- Call QueryStatusChangeEndpoint to send the first SCE request in Query Bus Releations.
- Complete implementation of StatusChangeEndpointCompletion. Queue a work item for DeviceStatusChangeThread, which will be used to initialize the usb device and create related device objects.
svn path=/branches/usb-bringup/; revision=51576
- Start work on reimplementing UsbHub driver.
- Implement SubmitRequestToRootHub, QueryStatusChangeEndpoint, QueryInterface, GetPortStatusAndChange, SetPortFeature and ClearPortFeature.Handle QueryBusRelations.
- Partially implement PNP handling for FDO. When starting the device get all the information about the RootHub the driver will need and enable Power on all ports.
- Partially implement PNP handling for PDO, QueryId and QueryDeviceText.
- WIP
