There is no way that the C64 could drive the USB stick directly.
Bit-banging USB signals is hard, and no, you can't do it on a 1 MHz
machine as the minimum baudrate is 1.5 Mbps. Also making a USB host
(which is needed if you want to use a USB memory stick) is much harder
than making a USB device, even with dedicated microcontroller
peripherals. It's mostly the software complexity required. On the other
hand, there are ready-made solutions for that:

than the tape port...
