Regards to the USB power off the one cable, its likely it needs a USB C port in the computer that can also handle greater then 10 watts out, not all USB C are the same and the max wattage a usb 3.0 port should of been 18 watts, but this also depends on the voltage/current handshake between devices if its gonna say lets use the 18 watts. I have this unit and it did it the same for me where the same port would be able to power other interfaces by it self with no additional power to the device required.
Dude I've been trying to get my Scarlet 4i4 working for 4 hours, I've probably watched around 20 videos looking for the answer and I didn't think to take that usb adapter off the usb-c cable. That literally fixed my problem thank you!!!!
I own a Scarlett 2i4 2nd gen and have been using it for a long time. I am not sure if it is worth the upgrade. Also, neither of my laptops has a USB-C port and they both power my gen2 device easily whereas gen4 would require carrying a power adapter, which is really annoying. I am not sure if there's anything related to the audio performance that makes the upgrade feasible.
Same here. I have an sm58, korg M50, and Roland td-17kvx all hooked up to it. Running Cakewalk by Bandlab on a Windows 11 desktop. Functions flawlessly once they released the update which fixed the app hanging and crashing when exiting. This didn't affect the unit but am glad the app closes normally now.
