You could create a custom HID input report.

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.
