- Start implementing error handling.
- On errors use a worker thread to attempt a recovery. If successful restart the operation that failed.
- If STALL_PID is received reset the pipe of the device.
- Not entered into code path yet. WIP.
svn path=/branches/usb-bringup/; revision=51754
- USBSTOR_SendRequest: The buffer for read/write may not be NonPagedPool, which is documented as a requirement for using MmBuildMdlForNonPagedPool. Also locking the buffers pages is also not an option as the routine is called at DISPATCH_LEVEL.
It so happens that Irp->MdlAddress is valid for read/write operations. Use it instead of procedure above.
- Add a sanity check to make sure the Mdl does describe the transfer buffer.
Fixes IRQL_NOT_LESS_OR_EQUAL bugcheck in windows. These changes also may fixed writing to device.
svn path=/branches/usb-bringup/; revision=51752
- Fix bug in read command, which uses wrong format. LBA address is stored in the CDB10 struct
- Don't build the mdl for nonpaged pool if the driver passes an mdl (i/o paging requests)
- Usbstor can now list disk contents and browse files when used in Windows XP
- Need to implement SCSIOP_WRITE to write files
svn path=/branches/usb-bringup/; revision=51694
- Handle SCSIOP_MEDIUM_REMOVAL
- Handle paging i/o requests. These request don't provide a data buffer in the srb, but the buffer is stored in the irp' mdl
- Fix the hack for unimplemented Mode Sense command
- Usbstor now completes initializes and receives read requests
- Still need to fix read request, as Windows XP fails to recognize the disk format, WIP
svn path=/branches/usb-bringup/; revision=51693
- Add a check at USBSTOR_FdoHandleStartDevice to make sure the device uses Bulk Transfers.
- Use macros for initializing the Urbs. The macros ensure that the proper fields of the URB are set correctly.
Fixes failing of getting device descriptor and getting devices BlockLength.
svn path=/branches/usb-bringup/; revision=51691
- Only get the string descriptors if they are available. Fixes crash when using usb mouse and keyboards in windows.
svn path=/branches/usb-bringup/; revision=51688
- Modify BuildBulkTransferQueueHead to support TransferBufferLengths larger than PAGE_SIZE * 5.
- Acquire a SpinLock before adding QueueHeads to AsyncList and PendingList.
- Dont request a new QueueHead for incomplete transfers in QueueHeadCompletion, as the memory for the just completed QueueHead has not been released yet. Doing so overwrites the m_TransferDescriptor[x] members with new address resulting in memory leaks. Instead request a new QueueHead after the QueueHead has been freed in QueueHeadCleanup.
- Fix a bug where a QueueHead was removed from the m_CompletedRequestAsyncList instead of the m_PendingRequestAsyncList.
- Temporary hackfix InternalCalculateTransferLength to return the TransferBufferLength. This hack will be removed as soon as possible.
- With these changes the hub and ehci driver allow viewing content of and transfers to/from usb disks.
svn path=/branches/usb-bringup/; revision=51684
- 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.
svn path=/branches/usb-bringup/; revision=51672
- When clearing feature port reset, remove the flag from Change and if the port is hardware enabled set the enable flag in Status.
- When checking port status, if Change has any flags set an SCE request most be completed. Verified while writing usbhub driver in xp.
- Probably fixes a case where an endless loop of completing SCE requests.
svn path=/branches/usb-bringup/; revision=51642
- 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.
svn path=/branches/usb-bringup/; revision=51641
- Some devices implement a default Language, LangId of 0. Some do not. Use LangId 0x0409 (English) until LangId is implemented.
- Remove an unused variable.
svn path=/branches/usb-bringup/; revision=51622
- 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.
