I’m more than happy to put my cube ide project on github for people to start playing with.

Video out works as does the riser accelerator port :)

Yes please.
I am waiting for my gear to arrive. I just bought cd32.
My f407 dev board arrived today, so I should be ale to start learning how to use hid libraries.

I may be wrong but this device may be only to serve as a host for 1 device with no support for hubs.

I did find this in stm32 usb docs:

Can the USB host library handle devices connected through a USB HUB?
No.The USB host library does not support HUB class.
Does the USB host library allow to handle multiple configuration devices?
No. Only single configuration devices are supported

So this might be limitation for mouse+keyboard combo?

I'm expecting to do a second revision of this board with 2 ARMs on it. But yeah thats probably why only the keyboard shows up.

Why not just build the riser rather than play around with dev boards? I never found dev boards to be particularly good for learning on.

I am planning to do the order this week and build it over following weekend.

I guess meanwhile I might be able to hijack gotek and debug firmware there :D

You should be able to get a Blue Pill and a cheap ST Link v2 next day delivery from Amazon. You’ll need the ST Link either way.

Generally we might not want to use the USB library and maybe find porting the MiST USB code is better.

May I ask what bom is for non ARM stuff?

Here is the full bom from the eagle file.

Thank you.
Parts ordered in Mouser. It took me a while to find connectors. I had to order db23 on ebay.

Ah supaduper would have set you up with a DB23.

Looking over the MiST firmware.. it basically has USB hub support via reasonably clean interface for a max3421e usb chip.

So essentially if we write something that acts like that API in MiST then we would get all that support + FAT + Ethernet etc.. at least in theory. Then we'd need to interface it to the Amiga somehow but I can do that part. Might need a bigger CPLD.
