- Add asserts
- Rewrite queue methods to accept the FDO only
- Fix multiple synchronization bugs
- Don't start next irp before current irp has completed
- Use contiouslogicalbytes blocks from srb
- Should fix race conditions
svn path=/branches/usb-bringup/; revision=51764
- Silence warnings
- Silence traces
- Add asserts
- Add code to detect usb reset in progress. In that case cancel the request
- Add more code to synchronize urb action
- WIP, still hangs are observed
svn path=/branches/usb-bringup/; revision=51759
- 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
- Implement retrieving drive capacity
- Use constant from scsi.h instead of defining own format
- Don't reset returned parameters length to zero, as ioctl handler might set it
svn path=/branches/usb-bringup/; revision=51608
- Make DeviceId generation to match ms usbstor
- Don't hardcode the device type in USBSTOR_PdoHandleQueryHardwareId
- Don't hardcode device type in USBSTOR_PdoHandleQueryCompatibleId
- Hackfix generation of instance id
- Add comments
- Cleanup code
- Usbstor now receives ioctl from disk.sys
svn path=/branches/usb-bringup/; revision=51582
- Rewrite hardware id / instance id matching
- Implement support for compatible id
- UsbStor still not attached to disk.sys, needs more research on how to get this done
svn path=/branches/usb-bringup/; revision=51580
- Don't free device descriptor if it failed to acquire it
- Don't move out of usb configuration array. Found by special pool
- Fix bug when storing interface information which lead to a overwrite
- Implement retrieving generic type for device
- Fix bugs in QueryDeviceId
- Implement querying hardware ids
- Implement querying instance ids
- With these changes, usbstor now initializes and create pdo, which is also enumerated
- Needs more code / fixes so that disk.sys attaches to usbstor
- WIP
