- Store number of bytes transferred in the transfer descriptors
- Perform queue head completion when the door bell ring has been acknowledged. Fixes race condition between multiple irps in the async list
- Fix calculation of transfer length when the request is an bulk in operation
- Use EndPointDescriptor member to access transfer type / pid direction
- Use MmGetSystemAddressForMdlSafe to retrieve system address for urb buffer
- Fix check if first transfer buffer finishes on first size if the size is of page_size
- With these changes and little luck and good weather, usb mass storage devices have been seen to work in Windows XP SP3
- Code inspired of mjmartin usbehci driver and Haiku's usb stack
svn path=/branches/usb-bringup/; revision=51506
- Port URB_FUNCTION_CLASS_INTERFACE from mjmartin usbehci driver
- Fix typo in interface declaration
- Disable assert for now
- Return irp status pending when irp is added to the queue
- Fix bug in InternalGetPidDirection
- More work on the bulk transfers, not yet working
svn path=/branches/usb-bringup/; revision=51501
- Fix a type causing CommitIrp to fail.
- Add a sanity check in StatusChangeEndpointCallBack to check that a pending SCE irp is queued.
- Start Implementing Bulk Transfers. Needs more work.
svn path=/branches/usb-bringup/; revision=51493
- Move error checking if controller reported an error inside the door bell ring check block
- Extend interface of IUSBRequest to include DeviceAddress, which is needed to retrieve configuration descriptor of newly set address
- Allocate CtrlSetup from nonpaged pool
- Release setup packet on cleanup
- Devices now receive an device address
- Currently asserts while retrieving configuration descriptor as this code path is not yet existant
*** Assertion failed: Urb->UrbHeader.UsbdDeviceHandle == NULL
*** Source File: d:\usb-bringup\drivers\usb\usbehci_new\hub_controller.cpp, line 1118

- Change interface to return real async queue head
- Set the async queue head register after the controller has been started
- Enable async queue in StartController
- Port DumpDeviceDescriptor from mjmartin usbehci driver
- Remove pseudo queue head from usb queue, instead use the real async queue head exported from IUSBHardwareDevice
- Get physical address for transfer data in BuildControlTransferQueueHead
- Retrieving device descriptor now ~works, currently stops at setting device address (needs more work)
svn path=/branches/usb-bringup/; revision=51476
- Check if the current request type is supported (currently only control is supported, bulk will be implemented soon)
- Fix bug in IUSBRequest::CreateQueueHead
- Code runs now until first device descriptor get request (async / periodic queue not yet enabled)
- mjmartin usbehci status not yet reached
- Let the fun now begin ;)
svn path=/branches/usb-bringup/; revision=51474
- Return the physical address of the async queue head in CUSBHardwareDevice::GetAsyncListRegister
- Remove superflous entries from queue head structure, they are processed within IUSBRequest class
- Remove USBHI_GetPortHackFlags, this function has been deprecated
- Add interface functions for IUSBRequest / IUSBQueue
- Callback into IUSBQueue when a hardware interrupt arrives
- Implement callback function to check for completed queue heads / free completed queue head depending on the Async Advance interrupt bit
svn path=/branches/usb-bringup/; revision=51466
- Create member for storing the request object
- Add interface function which is invoked when the queue head should be freed
- Add support functions which deal with completed queue heads
svn path=/branches/usb-bringup/; revision=51440
hub_controller:
- Implement StatusChangeEndpointCallBack called by HardwareDevice class when port status has changed on controller.
- Move Status Change Endpoint query code to IQueryStatusChageEndpoint as it is also needed by StatusChangeEndpointCallBack.
usb_request:
- Implement InternalCreateUsbRequest.
usb_queue:
- Implement CreateUsbRequest and AddUsbRequest
hardware:
- Implement GetAsyncListRegister and GetPeriodicListRegister.
- Implement SetStatusChangeEndpointCallBack for setting callback and context. Call the callback when a port status changes.
- Initialize the UsbQueue after creating the AsyncQueueHead, as the UsbQueue calls will call back with GetAsyncListRegister.
svn path=/branches/usb-bringup/; revision=51407
- Fix warning because comparing signed vs unsigned
- Implement function for retrieving the device descriptor
- Implement function for retrieving a configuration descriptor (including contained interface descriptor and endpoint descriptor)
- Cleanup interface for IUSBRequest:
- When caller initializes IUSBRequest with an IRP, then the operation mode is asynchronously. Therefore when the request is completed, IUSBRequest::ShouldReleaseRequestAfterCompletion will return true, which makes IUSBQueue call Release on IUSBRequest
- When the caller initializes IUSBRequest with an setup packet, the operation mode is synchronously. After submitting the IUSBRequest to queue, the caller should call IUSBRequest::GetResultStatus. This function will then block untill the operation has been completed. However, the caller needs to call Release() as those requests are not cleaned up by the IUSBQueue
svn path=/branches/usb-bringup/; revision=51406
- hub_controller: Implement Status Change Endpoint for RootHub.
Handling the URB can return STATUS_PENDING, as in the new SCE code. Check for this before completing the Irp.
Uncomment calls to PortStatus, SetPortFeature, and ClearPortStatus now that they are implemented.
- For function receiving a port number check that its not larger than the actual number of ports on the controller.
