I see other threads mention /boot/config.txt -- but I don't see such a file.

I made a /boot/config.txt and added
usb_max_current=1
but it does not seem to have changed anything.

The parameter is max_usb_current, and in the meantime setting this parameter to 1 is obsolete because already set to 1 per default.

You should have a /boot/config.txt. Make sure that /boot is mounted
