I am having troubles with powering my brand new Raspberry Pi 4.
If I insert more that 2 usb devices and power it up, that it won't boot and a red led will start blinking.
The funny thing is that these 3 usb devices that I want to use with the raspberry doesn't require to be powered by him, as they are satellite tuners with their own power supplies. Note I am using the original Raspberry power supply usb-c
But this is the most strange behavior: If I unplug all usb devices, power up the raspberry seeing the green light blinking and right after insert all 3 usb devices, then everything is working fine -> raspberry will boot correctly and will recognize all usb devices allowing me to use them.
Initially I thought about a hardware problem of my Raspi4. So, I tried with another Raspi4 with another original power supply and had the same problem. Lastly, I tried to do the same with my old Raspi3 (not 3B+) and it worked immediately without any issue.
So, I assume it is a raspberry pi 4 specific problem.
Is it possible to solve the problem by changing some settings, maybe?
