I switched up to Kernel 3.12 and that certainly fixed my stability issues with USB - haven't seen any USB related issues since then, wireless is fine, 3G modem is fine, everything working. Unfortunately I've lost my UARTs, but that's a different story and no doubt one that will resolve itself as more time is spent on getting 3.12 to stable.
Certainly for anyone else having similar USB issues, there's a good chance kernel 3.8 is the cause and kernel 3.12 is the solution On 8 November 2013 21:39, <philtu...@gmail.com> wrote: > I should also add that all of these USB devices work rock solid running > the same code and drivers on an intel laptop with Ubuntu. > > > On Friday, November 8, 2013 1:15:19 PM UTC-8, phil...@gmail.com wrote: >> >> We have a system with many USB peripherals, and we have done a lot of >> experimenting with them. >> Some peripherals play nicer than others, and some cause problems right >> away.
