Hi Matthias, It looks like you are running an older version of SeaBIOS (from 2013). There were a number of USB fixes since that time. It also looks like you are running a custom (non chromeos) rom. I recommend you upgrade to a more recent version of the software - either from where the custom rom was originally obtained or from another source. The coreboot download page ( http://www.coreboot.org/Download_coreboot ) lists this site as a source of Chromebook roms: https://johnlewis.ie/custom-chromebook-firmware/rom-download/ If you continue to experience USB problems after upgrading seabios, then you'll need to obtain the coreboot and seabios debug logs. Briefly this is done on Linux with something like: $ git clone http://review.coreboot.org/coreboot.git $ cd coreboot/util/cbmem/ $ make $ sudo ./cbmem -c The logs should be forwarded to the seabios mailing list ( [email protected] ) along with a description of the problem. Cheers, -Kevin -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
