+Q: Why isn't BFGMiner performing well or working on my Raspberry Pi?
+A: Raspberry Pis have hardware defect(s) which affect USB devices to varying
+degrees. Some devices will never be able to work on them, some work fine, and
+some require hacks to workaround the problem. One common workaround is to add
+the dwc_otg.speed=1 parameter to /boot/cmdline.txt. Note that this will slow
+down the USB bus to USB 1.1 speeds, which also affects network bandwidth since
+the Raspberry Pi uses a USB network interface. You may wish to consider
+upgrading to a BeagleBone or UDOO controller.
