A test with Windows might be more informative, if you can manage to do one. Perhaps the Windows driver knows how to configure the device to run at higher speed. Also, curiously enough, when I did a web search for reports of problems with this chip, the vast majority of messages were about it not working with Linux at all because Debian/Ubuntu did not include sufficiently up-to-date drivers. People had to download driver source code from a github project and build and install it for themselves in order to get the device to function. They didn't mention what speed it used on the USB bus.
