It did the trick for now. Should I expect it to survive a reboot?

No.

You can either add a file to /etc/security/console.perms.d to set the user permissions just for your scanner, or if you want to make all usb devices available you can just put this into /etc/security/console.perms.d/usb.perms:

<usbdevices>=/dev/bus/usb/*/* <console> 0600 <usbdevices>

You could also use the "big hammer approach and just put the appropriate chmod command into /etc/rc.local

Any idea what hp-scan does with the other file under /dev/bus/usb ?

No idea.
