[Qemu-devel] [Bug 1772165] Re: qemu-system-arm: -device usb-host, bus=001, vendorid=0x04f2, productid=0x0111: Bus '001' not found

[Peter Maydell <peter.maydell@linaro.org>]

This is for raspi3 but may be a useful reference:

Probably what you're hitting is that the kernel/dtb default to the
second serial terminal, so you can try adding 'console=ttyAMA0' to the
-append options, or alternatively maybe using -serial null -serial stdio
to drop the 1st serial output and send the second to the terminal.

Since the raspi networking sits behind USB, QEMU doesn't support that,
so no ssh option, I'm afraid.
