In basic when going via setup the usb tab is missing, so unable to change usb b mode , we updated to latest firmware but still no joy
Apart from that connecting to a PCB does loads a usb device but doesn’t show as a sound device on example software like audacity, but we assume it’s because of the first issue
In the release notes included with the firmware, or in the manual, you can find out, that with 1.6 also SQ no longer has separate USB modes.
Depending on the computer you’re using, you may need to install the appropriate audio drivers.
