This device is 10Mbps half-duplex only, hence 51 1.32.2.2 bouyer * there is no media selection logic. The MAC supports a 128 entry 52 1.32.2.2 bouyer * multicast filter, though the exact size of the filter can depend 53 1.32.2.2 bouyer * on the firmware. Curiously, while the software spec describes various 54 1.32.2.2 bouyer * ethernet statistics counters, my sample adapter and firmware combination 55 1.32.2.2 bouyer * claims not to support any statistics counters at all. 56 1.32.2.2 bouyer * 57 1.32.2.2 bouyer * Note that once we load the firmware in the device, we have to be 58 1.32.2.2 bouyer * careful not to load it again: if you restart your computer but 59 1.32.2.2 bouyer * leave the adapter attached to the USB controller, it may remain 60 1.32.2.2 bouyer * powered on and retain its firmware. In this case, we don't need 61 1.32.2.2 bouyer * to load the firmware a second time. 62 1.32.2.2 bouyer * 63 1.32.2.2 bouyer * Special thanks to Rob Furr for providing an ADS Technologies 64 1.32.2.2 bouyer * adapter for development and testing.
