HBA have direct accesss to SrbExtension?

WDK docs says, The memory at SrbExtension is not initialized by the OS-specific port driver, and the miniport driver-determined data can be accessed directly by the HBA. The corresponding physical address can be obtained by calling ScsiPortGetPhysicalAddress with the SrbExtension pointer. Does it mean that the memory buffer allocated for each Srb Extension is physically continues and can be accessed by HBA using DMA directly? Thanks!

WinUSB as a functional driver to replace an existing HIDUSB kernel mode driver

I am looking for the simplest way to replace the driver of an existing USB optical mouse. (This is an experimental project) I know i could write a KMD to replace the driver but reverse engineering and existing device and debugging KMDs is challenging at best. Basically im looking read the opical mouse input data to use for my own purposes without the using it to control the mouse pointer and buttons. Can this be done? If not, what would be the best approach?

DTM failed "Verify WDF Coinstaller Version for KMDF"

I have an unclassified USB device driver built in XP driver environment. The driver package uses the WDF coinstaller C:\WinDDK\7600.16385.1\redist\wdf\x86\WdfCoInstaller01009.dll. The DTM (DTM version 1.5.7565.000, WTT version 2.2.2098.0) fails the KMDF coinstaller version verification test for the XP, Vista 32/64 and W7 32/64 clients. I've checked the date/timestamp/size of C:\Winodws\System32\WdfCoInstaller01009.dll on each client against that of the driver package and they are the same. Does anyone have any tips on how I can track this failure down?

I'm trying to write a driver to present a ram disk. I have a FPGA based PCI card, but the RTL in FPGA is unable to handle the DMA operations.

SRB_IO_CONTROL ioctl call from user application

hi all, i tried to send the command IOCTL_SCSI_MINIPORT in scsi device and it is working fine. but i am facing error with storport miniport driver. in scsi miniport driver i am taking handle with \\.\PHYSICALDRIVE# and it works but i found from web that it doesnt work with storport miniport driver. as we have to get the handle with \\.\SCSI#. is it the only way to get the handle in storport? is it possible to create handle with the disk number of the driver letter like \\.\PHYSICALDRIVE# or \\.\D: and send IOCTL_SCSI_MINIPORT call to miniport driver? please help me, thanks

WLK x64 question

hi May I ask some WLK question here, is there some specific WLK Newsgroup for WLK? Should we generate test signature on Win7 x64, can we press F8 and disable driver signature checking during system boot ? Thank you .
