This module lacks complete integration into UI Flow and more documentation.
On the page https://shop.m5stack.com/products/usb-module
there is listed
Applications
USB key logger
Read and write U disk using M5Core
but where are the Applications ?
All we need is a comde example and a good documentation how to read data from this module, to have a keyboard connected
even an example how to read the raw data from the usb would he helpfull.
thanks in advance

6 Months later. Just flashed the Core S3 with the newest UiFlow 2.0 Alpha and still the modules are not integrated!
Do you really want to sell the Core S3 ? without complete software support, the use cases for the Core S3 is very, very limited.
Have tried to burn the CoreS3 Linux Port with the M5Burner.
But there is no output on the uart0, nor on the USB-C virtual com port.
Also nothing on the screen.
How did you make it ?
The M5Stack Core S3 is now released for 6 Months and still the uiflow 2.0 is in beta phase and supports 2 Mopdules only.
I'm asking me for what the Core S3 can be used ?.
In the M5 Burner, there is no UI Flow 1.x for the Core S3!
So at the moment the Core S3 has only limited functionality with the UI Flowe in alpha version.
Is this the quality of M5 Stack ?
@uktechguy
correct. That's called product placement.
No matter if the software is avaialble, ripe or not.
There are other new products with the ESP32 S3 pushed on the market, also without software support or only with a small demo app.
Ui Flow 2.0 looks nice. But it lacks functionality.
Tested with a new Core S3 and wanted to test out the built in Camera. But how to do it either in micropython or with blockly ?
Once you start selling the devices, the software must be ready and support all features of the device.
In my case I wanted to test the camera if it is possible to use the built in camera as a barcode reader, this would be a great application.
Second question to uiflow 2.0: Where have the examples gone ?
Even as an experienced programme, the demos are a good starting point for testing out a device or a unit.
Third question: How about the support of the stackable-modules for the Core S3 ? How to access them in the UiFlow 2.0 ? can we reuse the modules for the older M5 Stack models ?
@ajb2k3 said in UiFlow 2.0 Alpha verison discuss(how-to, bug, feature request or sometings):
@flex Some people and groups cant use the cloud platform and so local programming like with the microbic and RPI is needed for them
This is true. If you build an internal application for a company on the internal network, the devices will not have cloud access or they have to switch always the wlan.
A Desktop uiflow version is still a good alternative to the cloud version !
In UiFlow using the get interface mac config.
it reports the mac in a binary version i.e. b'\xa4\xcf\x12m\x95\xa4'
This is not usable!
It must be formatted in the ususal format with 6 hexadecimal bytes
There is an easy solution on that:
import ubinascii
mac_hex = ubinascii.hexlify(wifi_mac,':').decode().upper()
and then the mac address is format as example: A1:C2:00:FF:45:E5
Please include this bugifx in the next UiFlow version.
y la otra manera es de connectar el Atom con USB al PC y usar M5Burner. Abre la configuration de WiFi / inalambrico / modo de menu etc. y aya se ve el API KEY
When using the EasyLoader_Atomic_GPS.exe the GPS data are transferred, it takes some time for initializing, but then it works.
Using the newest UIFlow version it does not receive any data, even after many hours outside under the sky.
Maybe my UIFlow sketch is wrong. As there is no demo, nor a documentation what must be doen to initialize the Atom GPS to make it work under UIFlow ?
A very nice tool, the M5Stack Atom Display.
Finally, we can connect a bigger display where needed.
But it lacks the connection of the touchscreen, a keyboard or a Mouse and the graphical options as there are for the Core 2.
So what is missing is an USB connection and an integration for the touch screen..
Adding additionally the LVGL to UIFlow would create a killer application!
Would be perfect to use with the M5Stack Atom Display with a 7 inch display.
But does it run on an Atom ?
I guess the difference is based on the version.
1.7.5 and 1.10.5 are not the same.
You have to download the newest version here : https://static-cdn.m5stack.com/resource/software/UIFlow-Desktop-IDE.zip
this is Version 1.9.5
M5Stack announced that this is the last offline version.
In future, there is only the online version available.
For most users sufficient. But if you have to programm severla devices for a company internal application, wihtout cloud and internet access, how would you do that ?
The USB Module is only partially isable.
The GPIOs and a HID Mouse are accessible.
It is missing a HID-Keyboard integration and the integration as USB-Serial Port for Data Communication.
@brus
In my opinion, do a hardware fuse is not a good idea, because updating the programm would not be possible anymore.
But to have a password protection would be good.
Becuase when the devices are spread or installed. People could overwrite the firmware or the development using the uiflow webapplication, they just need to know the API number and thats easy to find when booting up and changing the menu.
if on Uiflow you must enter a password, this would also help to protect from overwriting the programm but you would be able to install an update.
As I did not find a recent post about the USB integration in UI flow, I'm creating a new one.
In the current version of UI Flow, there is integrated how to use a Mouse.
But using the USB Module, how can we read text from barcode reader or a keyboard ?
@ajb2k3
This looks very nice, I'll try it out.
Thanks for your post !
Try to update to 1.10.4.1
does this solve the issue ?
I've upgraded the M5 Core to latest Firmware V1.10.4 and M5 Core 2 to 1.10.4.1
Additionally found another bug:
when using the Online Ui Flow and adding the block for getting ifconfig 
then it creates a runtime error. The cause is:
blockly adds text "wlan.ifconfig"
but it must be "wlan_sta.ifconfig" and then it runs
The same issue als on a M5 Core2 it does not show an error message, just the screen stay white :-(
what a poor software quality.
Thanks a lot for your test.
My code also uses the wlan.ifconfig this way you can see the ipaddress, gateway and DNS.
I've upgraded the M5 Core to latest Firmware V1.10.4 and I still can reproduce the error that it does not work with local DNS.
Even if the M5 Core would use the firewall as the DNS server, this would work as well.
