While I was working this morning I ran into some issues with an app and went to check if the Console (under
/Applications/Utilities) was reporting anything.
Unfortunately the log was filled with some USB device timing out with the following error:
AppleUSBEHCI::Found a transaction past the completion deadline on bus 0xfa, timing out! (Addr: 5, EP: 1)
This timeout was annoyingly happening every few seconds. The error did give me a few clues. It was happening on USB bus
0xfa on a device attached to address
To find the device in question I generated a System Report (
> About this Mac > More Info > System Report) and looked for the USB bus with the same address.
Then it was just a question of going through the devices connected to this bus that had the address in question.
Found you! The device in question was the Garmin ANT+ stick that transmits data wirelessly from my Garmin Forerunner 610 watch.
Unplugging it fixed the problem and the Console stopped being flooded.
