Is there any way to log to anything but a laptop or an expensive CAN logger?

The internal data logging isn't big enough for my needs and obviously not ideal with limited write cycles.

Is there no way the USB can be used to output to a USB stick or something? Or at least specs for USB so that it could be read by a Raspberry Pi or something?

I'm sorry, but this is not possible.

If you want to make your own datalogger then if you use Bluetooth https://www.hondata.com/downloads/Bluetooth.pdf then your datalogging will be as long as you want.
