On Linux, you may need to add the file 99-alchitry.rules to /etc/udev/rules.d/ with the following contents.

[code]SUBSYSTEM!=“usb|usb_device”, GOTO=“ft2232_rules_end”
ACTION!=“add”, GOTO=“ft2232_rules_end”

ATTRS{idVendor}==“0403”, ATTRS{idProduct}==“6010”, RUN+=“/bin/sh -c ‘echo $kernel > /sys/bus/usb/drivers/ftdi_sio/unbind’”, MODE=“0666”, GROUP=“dialout”, ENV{ID_MM_DEVICE_IGNORE}=“1”


Also make sure the group “dialout” exists and your user is a member of it.

On Windows, if it doesn’t find the board, you may need to manually install the D2XX drivers from FTDI https://ftdichip.com/drivers/d2xx-drivers/
