> http://www.peach.ne.jp/archives/rpi/patch/dwc_otg-rpi2-20150516.patch > > This patch is subset of my USB patch of ODROID-C1 4x faster version on 1Gbps. Previous subset does not work correctly in ratecheck. I don't know a reason but same code from ODROID-C1 version works. I re-create the patch as dwc_otg-rpi2-20150518.patch. http://www.peach.ne.jp/archives/rpi/patch/dwc_otg-rpi2-20150518.patch Please use it instead. If you already applied 20150516, please remove it by: # patch -R < /path/to/dwc_otg-rpi2-20150516.patch Then, apply new version. Sorry for inconvenience. The below log is patched result on RPI2 using iperf3(/usr/ports/benchmarks/iperf3).
