First, thank you very much for the new release.
Unfortunately the problem with the USB-Port permanently resetting on Linksys MR8300 or maybe all ipq40xx platforms still exists in latest OpenWRT v22.03.01
In short, upon connecting an external usb storage device, the port keeps resetting / disables power to the device for short time leading to permanent connect / disconnect loop.
Please see Linksys MR8300, OpenWrt 22.03.0-rc4, USB port-powered storage devices not working - #29 by Barney for details. Maybe it hasn't come to the developers attention yet, since it is in another forum.
Is there anything I can try to make it work?
