Hi, I'm using https://github.com/libusb and based on libusbK.sys. Per MS's link: https://msdn.microsoft.com/en-us/library/windows/hardware/ff538112%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396. It has hard-coded limit in there USB driver stack. Then what libusbK.sys and libusb done for this? If I need split my large chunks of data to smaller ones then call "libusb_bulk_transfer"? Or MS or libusb or libusbK have done the data *scaling* at lower layer for user? ------------------------------------------------------------------------------ _______________________________________________ Libusb-win32-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libusb-win32-devel
