The id1 and id2 bytes seem to change sporadically during the probe process, suggesting that the embedded controller (EC) is interfering. To be honest, it is unlikely that this laptop will ever be supported since it requires product-specific (and likely closed/proprietary) EC commands to prevent interference during the update process.
