Does this mean that a PicoMite can talk to four other PicoMites via their USB ports?

G'day Peter,
A huge thank you for this, it's been on my wish list since the very first PicoMite USB firmware was mentioned  

Regards,
Lyle.

This is insane. Might need to go grab a beer and ponder the possibilities 🍺

Awesome!  
Is it possible to do something else so that you can connect a USB Flash drive to a hub and have it available in the system as drive C:?

I guess USB laser-printer support will be next......  
You amaze us all, Peter.

I doubt if it will handle USB devices that aren't actually serial. That would rule out all types of USB flash drives, USB printers etc. Also, you can't set the baud rate so it's not something you could connect to a serial printer.

Time to plug some USB drives into a Raspberry Pi and turn it into a modernised  Commodore 64 disk drive. :)

I wasn't. :)
I think the possibilities of a high speed serial-controlled usb-connected (preferably) drive are definitely there. You need a command structure to talk to the Pi to give it commands and get it to accept or send data over the link. Obviously it needs to be set up to use its USB system in a suitable mode and respond to those commands. You could then access whatever drives or devices that could be plugged into a Pi. No need for the latest and greatest either, a Pi 3 or 3B would probably be adequate as a file server. Of course, this may not be possible. I don't know enough about the Pi. Or much else, for that matter. lol I do know that the Commodore 1541 floppy drive was on their own serial version of the IEEE-488 interface though.

A 1541 floppy emulator already exists for the Raspberry Pi.

However, an ATMEGA1284 is sufficient for this.

And I just found this: Someone is working on a solution using a Pi-Pico:

By the way: Happy Easter everyone!
