Hi everyone,
I hope someone can help me.
I try to port an USB driver from XP 32 Bit to Win7 and XP 64 Bit. I made all changes in the code and compiled it with WDK Checked Build Envirement for Win7 x64. No errors, no warnings and also OACR does not report warnings or errors.
I testsigned die resulting driver and tested it with the virtual machine form VMWare using XP 64Bit and Win7 64 Bit.
There seems to be no problem with the driver in XP 64Bit. The driver installs and works. I can read the expected information form the USB-Hardware.
But when I try to install the driver on Win7 64Bit the installation seems to start correctly. I choose the INF-File and the driver installs. I get the dialog telling me that the driver was installed correctly. But when I then confirm with "Finish" Win7 hangs up completely (only hard reset works). When I then restart the machine the driver is in the USB-list of the device manager and it seems to work.
I also tried to install the driver on a real Win7 machine several times. Sometimes it works, sometimes I get a blue screen. So I think there is something wrong with my driver, but I've no idea how to find this error.
