One thing I forgot to point out is I used the identical kernel+modules for both setups. I would be interested to see if that makes any difference for you. I can't fully test it as my board doesn't have a Linaro kernel. So there are four combinations - I only tried the first two: Yocto kernel + Yocto rootfs Yocto kernel + Linaro rootfs Linaro kernel + Yocto rootfs Linaro kernel + Linaro rootfs > On Fri, Mar 14, 2014 at 7:38 AM, Gary Thomas <[email protected] > <mailto:[email protected]>> wrote: > > On 2014-03-12 13:11, Rick Bianchi wrote: > > usbip from /usr/src/kernel/drivers/staging/usbip > > I finally managed to make this comparison.
