USB 3.0 to gigabit ethernet keeps crashing system with 10.10.1/2

I have this Realtek USB 3.0 to gigabit ethernet adaptor. Using either the included drivers for OS 10.8.x or the official Realtek drivers from December 2014, it hard crashes the system every 5-10 minutes. I have about 120 GiB of data to transfer to a 13" Pro Retina and no external HDD - is there a way to make the Realtek adaptor work under 10.10.x or a quicker way to transfer my data?
