CPC ROM emulator using a Raspberry Pi Pico

[RetroDave]

This looks like a great project.

I'd be very interested to hear how version 2 is progressing, especially the disk controller support. 

It would be great to have a cheap and simple to build floppy emulator. Existing CPC options seem limited and expensive. 

The memory expansion would be good too if that's possible. 

There are some similar projects for other platforms that are Pico based like the A2Pico card for the Apple II and PicoMEM for ISA PCs.

Hi all I'm new to this site.
I found this project while searching the internet and decided to build it.
The rom side of things all appears to work great but the USB CH376 USB board I haven't managed to get working.
Just wondering if anyone has it working as I've been searching and I've not really found much on it apart from on the github page where it refers to the Albireo wiki.
I've tried different versions of the Albireo & Unidos rom I currently have I think the latest version from https://unidos.cpcscene.net which are Unidos 1.51 and Albireo 1.41
I've tried 4 different USB sticks ranging from a very old drive up to a newish USB 3 drive you can still buy new today.
When I put a USB stick in the drive the LED on the USB stick comes on for about 1 second and goes off.
The USB sticks are formatted to FAT32
The drive I wanted to use I only left 2 or 3 files in the root of the drive just in case of any issues with the number of files in a directory.
The 74LS688 chip I got  5 of them and I've tried, I think 3 of them.
I've tried a different PSU for the Amstrad.
I've tried moving roms around but my config currently looks like this:
L:OS_6128.ROM
0:BASIC_1.1.ROM              V1.20
4:Utopia                            V1.25
7:Unidos                            V1.51
10:Albireo                          V1.41
11:Picorom                        V3.11
To try and access the USB I've tried a few different commands of which I know some were not going to work as I was typing them but was just wishful thinking.
|drive  is the command that I thought would work and it doesn't show any USB drive.
Has anyone got any ideas as I could be doing something stupid and missed something very basic?
