There is no need to have the various pty files clobber the /dev

* Enable verbose detection, add CP2012 based serial adapter support
* Only enable USB1.1 HCD for now to fix the detection of the USB serial

* Enable more filesystems in the config to allow upgrading the boot
partition during the runtime (after installing the right codepage)
