All,
Thanks I will follow that direction and try to use Hid class for passing
proprietary information.

See if you can find a copy of "USB Design By Example" by John Hyde.
It's a bit old but still valid I think for using driver-free HID methods to
communicate arbitrary information with your custom HID device. I used it for
the first ever USB device I made, and successfully transferred low data rate
information between the PC and the device. It was enough to allow me
eventually to download new firmware to implement a custom device once I had
worked out how to write a proper driver.

You could create a custom HID input report.

We won't write our own drivers instead we will use drivers provided by
Windows 7.
Is there a way to pass proprietary information (like error/log messages)
from a device to Windows
using standard Windows 7 drivers and API ?
If you are using the standard drivers, then all you have are the mechanisms
in the USB standard, and operating system log messages are not part of the
standard.
If this is absolutely critical to you, you can always insert a filter driver
to communicate with the device using vendor control pipe messages. Of
course, now you have to ship an INF file and worry about signing, which sort
of defeats the purpose of using the standard drivers to begin with.
