I have found online a usb host that allows for FTDI drivers: http://www.hobbytronics.co.uk/usb-host-board-v2
Quoting the description it says:
"You can write your own software for the USB Host Board or you can download one of our free software applications. Downloading software to the board does not require a specialist programmer because it has a bootloader already installed.

New software is easily installed over a serial RX/TX connection, so you will need an appropriate connection to your computer. We recommend the FTDI Basic breakout board but there are many similar boards and cables available."
From what it sounds like, the bootloader comes installed already, but you can upload a custom script to this. Is this neccessary? I just want to use it in between my ESP32 and 3D printer. I need it becuase the 3D printer communicates via FTDI and the ESP32 can't be used as a usb host.
So with this usb host, it just possble to send data to the host and have it send that through a cable to the printer, without a script on the host?

I might be completely misunderstanding the description!

I hope this makes sense,
Bod

Nevermind, just been a bit of an idiot!

If I had read the description on the link you provided:
This software allows you to connect a USB serial device that uses an FTDI, CP210X, PL2303 or CH340G USB chipset, or is a CDC device to the USB Host Board or USB Host IC's and send and receive data.
It would have solved all my confusion.

Thanks,
Bod

I know that bit already, hence why the description says: I'm just not sure whether I still need a script along with the already installed bootloader.

If by 'script' you mean USB Host Configuration for the installed firmware then, yes if the defaults need to be changed. The bootloaders function is to upload new firmware if you want to change the USB host preloaded functionality. Once that's done the bootloader disconnects for normal firmware operation.

Ok, thats better than I thought.
I'm assuming by 'defaults' you mean thinks like baud rate, right?

Use the FTDI vinculum board allowing serial plus two usb hosts or two slaves or a combination thereof . IDE is free
All drivers included and many examples available.
Only one problem IDE will run only on Windows &*&^ and not on my beautiful handy nearly perfect Linux.
( Linux Wine won't do the job something with the way usb ports, on bit level, are being handled )
So I had to keep one Pc running windows.
