How can I force the system not to recognize a USB2.0 flash memory

You can't - it's negotiated at the host controller level, the OS isn't involved.
You can't force it to use USB2 mode when for some reason it's negotiated something slower. But you can *detect* that it's connected as a USB1 device and refuse to mount it, surely? And then the user will unplug it and plug it in again, until it works correctly.
Yeah, I guess you could write a udev rule that detected that case and flagged it such that it didn't get automounted.
