IIRC this is first time I see that kind of bug report. Seems like EM28174 starts failing I2C messages. -110 is ETIMEDOUT and is likely coming from the USB-stack. Is there anyone have seen similar situations when em28xx driver is used? Maybe overheat? regards Antti On 15.03.2012 22:14, Keith Edmunds wrote: > I posted the message below last week, but I've had no response. > > Is this the wrong list?
