Hello Securb,
H90 Firmware can only be updated on a desktop computer, not via Bluetooth. USB C should be connected directly to the computer, not using a hub of any kind. If you have tried the supplied USB-C cable and it still doesn’t work, please email support@eventideaudio.com for more troubleshooting steps. Once you send the message, you should get an almost immediate reply confirming they’ve received it. Be on the lookout in your spam or junk folders just in case.
