iMac keeps waking up from sleep

[jlyanks85]

Some reason my iMac has been waking up from sleep the last couple days. Thing is I have "wake for network access" checked off. So why would it still be waking up?

Thanks. I ran that terminal command on my iMac and I got wake reason EHC1 and EHC 2.

However, it is not exactly specific enough. As I have wake for network access turned off and only USB devices are hard drives…

I also have a wifi printer. Going to try unplugging the printer from the power outlet and see if the iMac wakes up tonight.
