Can we boot with USB devices attached?

I actually have a quick question. Should these drivers allow us to be able to boot with USB devices plugged in or will we still have to keep them unplugged until we’re at the desktop?

Unless there’s a gross bug, you can definitely boot with devices attached as you normally would. Remember that the Pi has an embedded hub (which is a “device” to our stack), plus the embedded USB-Ethernet controller (again, a “device” to us). Those will be probed and enumerated during boot. (So you may need to hide the USB-Ethernet driver if its not stable.)

Excellent. It should be interesting to experiment with!

Well, there’s a known issue with the current USB drivers that impose this arbitrary restriction :slight_smile: But as soon as the proper drivers are released, like Terry said, you could connect any USB device without fear.
