This applies to the 2i2, 2i4, Scarlett Solo and iTrack Solo
If you find that, after you connect your USB bus-powered Scarlett to your PC, the USB and gain LEDs continue to flash indefinitely, while Windows continues to attempt to connect the device (often denoted by a chime sound), this tends to indicate that the interface is not able to draw enough power from your computer.
In order to try and resolve this issue on our 2nd Gen Scarlett 2i2 & 2i4 interfaces, we have introduced a 'Low Power Mode'. This low power mode essentially restricts the amount of current supplied to the Phantom Power circuit, and therefore asks for less power from the USB bus, please note that the performance of your condenser microphone may be effected by this.
Our Scarlett Updater app, which includes the ability to activate or deactivate the Low Power Mode on 2nd Gen 2i2 & 2i4 is available HERE
If you own a 1st Gen 2i2, 2i4 or a Scarlett Solo, or the above low power mode is not resolving the issue fully with your 2nd Gen, we would recommend using a powered USB hub in order to resolve the issue.
Below are some powered USB hubs we have tested as working, other powered hubs may work but have not been tested at this time, testing a hub before you purchase is always preferable if possible. Please note that the hub must be powered from the mains in order to resolve the issue, bus-powered hubs will not work.
We will update this list as additional hubs are tested:
