In Linux you should do the following procedure for the USB:

1. Disconnect everything from the board.

2. Insert the card.

3. Apply 5V supply.

4. Apply USB (it is important to apply USB after you have applied the external power supply).

5. Wait 2 minutes.

6. In your computer search for ACMx device. If you don't know what it is, type:

dmesg -w

then disconnect the USB then connect again, you should get something like:

[27927.005275] usb 2-1.1: new high-speed USB device number 5 using ehci-pci
[27927.114108] usb 2-1.1: New USB device found, idVendor=0525, idProduct=a4a7
[27927.114112] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[27927.114115] usb 2-1.1: Product: Gadget Serial v2.4
[27927.114118] usb 2-1.1: Manufacturer: Linux 5.10.105-olimex with musb-hdrc
[27927.187852] cdc_acm 2-1.1:2.0: ttyACM0: USB ACM device
[27927.188277] usbcore: registered new interface driver cdc_acm
[27927.188279] cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters

Obviously it gets associated as ttyACM0 here.

7. Open picocom or other terminal software on the new ACMx device. Here I used command:

picocom -b 115200 /dev/ttyACM0

8. Login with user root and password olimex.

I only have a linux VM* that is installed on a windows who don't recognize the device so i can't put the device on the vm :') sorry.. (i've tried with a debian installed with wsl but dmesg gave me nothing)



Better use the Windows then. VMs do funky stuff with USBs and mess with USB timings. I wouldn't trust a VM for USB functions. Which version of Windows exactly do you use?
