I want to connect 10 Pi Zeros via Ethernet over USB to get 10 Pictures at the same time. My Host machine is a Raspberry Pi 4 4GB running Ubuntu 21.04.
I got everything running as I want to with 7 Zeros connected. Once i connect the 8th Zero all Zeros are disconnectiong and connecting over and over again plus I cannot use mouse or keyboard anymore.
It seems that the Pi 4 is running out of Memory/ RAM/ something else. Is there a way to give the USB Ports more "Power" so i can connect 10?
usbfs_memory_mb from the standard "16" to "1028" or even "2056" isn't solving the problem.
