USB driver not working on windows 7

**2muchreality** · 20-02-2009

I got a usb host client driver that works fine on Windows XP and Windows Vista but it causes an operating system hang on Windows 7. The initial exchange happens properly, device descriptors, configuration and interface descriptors are all got from the connected device without a glitch but as soon as a bulk transfer is initiated the system crashes. The exact point of the crash is when my driver passes an Irp for IOCTL_INTERNAL_USB_SUBMIT_URB to lower drivers using IoCallDriver. The IoCallDriver function does not return.

I am getting following debug analysis:
IoBuildDeviceIoControlRequestAssertion failure - code c0000420 (first
chance)

I guess that first of all you will have to solve your symbols to get a meaningful stack trace.

Thank you. I actually don know properly how to debug driver. Could you please let me know how to get these symbols fixed since whatever settings I try on Windbg I am always getting this message of wrong symbols.
