Usb hub booting problem rpi400

Tue Jun 15, 2021 10:21 am

Hi, I installed ubuntu on external ssd and while connected directly to rpi400, it boots swiftly. But since i connected it to AXAGON HUE-S2BP 4x USB3.0 CHARGING hub, which i need for overclocking, it does not boot and calls timeout. Did someone solved something similar?

This is almost certainly a lack of power from the power supply.
