@desowin maybe change the start type of the filter driver to "SERVICE_BOOT_START 0" could solve this problem. I'm develop a usb filter driver and test it in winToGo system, it...

tv_nsec is not monotonically increasing; it is periodic, so the calculated delta_nsec can be negative.
With this implementation, although it avoids the somewhat unsightly logic of the if statement that checks for negative values, there is a potential risk of overflow for the unsigned long...
I found the TIMESPEC_SUB macro in libusbi.h. I'm going to use this macro for implementation instead. I'll verify it after 10 hours and then give feedback on the results at...
