"Bonjour" doesn't work after sleep.

Why doesn’t USB 2.0 plugable gigabit ethernet work properly after sleep?

I have a server that is visible to machines on my network.
When my mac wakes up from sleep, the “plugable” usb 2.0 gigabit ethernet connection no longer sees the bonjour computer.

If I unplug the usb connection, then plug it back in, the server pops right up. (As the plugable ethernet is reinitialized.)

I should not have to disconnect and reconnect my usb ethernet dongle in order for it to work!

Does anybody have a solution to this?

(OSX Lion 10.7.2, with proper drivers installed.)

Hi Scott,

Looking through the Apple support site, I found a number of people reporting difficulty with waking the machine from sleep with Lion. Your issue sounds like the USB ports are not waking up until a device is plugged in. Here’s a link to a post that may provide some additional background.


Unfortunately it doesn’t appear there’s a solution as of yet. However, I’ll check around some more and post back here if I find anything interesting. Also, be sure to let us know if you find any fix in the mean time.

Sorry I don’t have anything more definitive at the moment!!
