I have since called the manufacturer of the docking station. They confirmed that this particular dock has the "feature" that it autonomously goes to sleep after 5 minutes of non-use when connected via USB. That's why nothing I did via the kernel helped. I guess I will have to ping the two docking stations every 4.9 minutes via a cron job to keep them awake. What a kludge. Other suggestions?
