Install Filter Driver Hi All, I want to install my disk upper filter driver for a USB mass storage device programatically. I think I need to use CreateService() and other routines to start the serivce. At the same time I need to add registry keys (UpperFilters key) under USBSTOR to install as filter driver. I'm not sure how to det... 19 Mar 2010 10:48
Driver Development - Digitally signing Hello, I would like to develop a driver. This driver emulates a sound card and is based on the MS Virtual Audio Device (Simple) of the WinDDK. Everything is working with WinXP x86, but when I try to install it on Win7 x64, it is disabled, because Win7 requires a driver to be digitally signed. I cannot affo... 18 Mar 2010 07:05

Nonpaged Pool Memory Limitation Hi All, I want to allocate two 1MB non-paged pool memories in my driver (using ExAllocatePoolWithTag). one for read and other for write. I would like to know what is the limitation of nonpaged pool. Is this dependent on physical memory? Actually, I have the option of using single 1MB pool both for writes and ... 18 Mar 2010 22:22
windows XP sp3 and usb priority I have a bulk usb device and the PC requests the status of the device polling a usb bulk pipe. Using Windows XP Service pack 2, the time of the status request (write request+read status) is less then 40mS. After installing service pack 3, the time of the status request could increase up to 600mS. I suspect tha... 19 Mar 2010 00:35
I'm having the same problem Hi guys, I'm trying exactly the same thing. I thought that I had to configure the base address in the INF file and then in the EvtPrepareHardware callback, read the translated resource address and write it to the GPIO Base Address thru the LPC (using CONFIG_ADDRESS and DATA_ADDRESS registers of the SCH), but accord... 19 Mar 2010 12:02
Please document setup for new WLK 1.5 IO Cancellation with Direct Could you please document how to set up the new WLK 1.5 IO Cancellation with Direct IO on network storage (Preview) test? Better yet, how can I avoid this job from running in the first place without causing a submission failure? This test does not really apply to our driver under test as it does not involve s... 16 Mar 2010 15:07
SetupCopyOEMInf windows 7 Hi I am facing a similar problem using DevCon to force update of driver I currently have under development. Worked fine in XP but with Win7 the old driver is reinstalled. Have tracked it down to the SetupCopyOEMInf that is executed as the installer processes the inf file. In my case what happens is that it sees... 19 Mar 2010 21:16
__imp_EnableWindow Here's the latest instalment of my apparently never ending saga of trying to get things to link! My latest linker error is: error LNK2001: unresolved external symbol __imp_EnableWindow I would have thought that the USE_MFCUNICODE=1 or USE_MFC=1 should have taken care of this linker error but apparently not. ... 22 Mar 2010 03:54
Bug in WDK Install process I tried to install the WDK (7.1.0) from a burned ISO image. However, a few seconds after the autostart shows the main DDK menu, I get a KitSetup Runtime Initialization Error! (Code:0x0007). The installer immediately crashes and exits. The problem is that 1) I use a dedicated SATA drive for my temporary file ... 16 Mar 2010 15:07 |
