The driver could try to resync better when bogus packets come in by searching down the packet for the ATM header, using the fact that the header should satisfy a CRC 8 checksum. I've always meant to do that one day, but never got round to it since it didn't seem too important. Maybe the time has come... > The only thing I haven't tried is using a different USB port, because > I only have one port which is fast enough! Should I try getting a > PCI card with an EHCI chip on it? My m/b chipset provides UHCI. Speedtouch modems are full speed devices, i.e. USB 1.1, so UHCI is perfectly good enough. Please try a uhci port. > Oh, and another thing. atmdiag keeps telling me there are 0 errors > despite all the messages. How can this be? ATM statistics are per ATM connection. To driver determines the connection from the vpi/vci pair. If it finds a bogus pair then it doesn't know which connection to attribute it to, so doesn't know which statistics to adjust. Ciao, Duncan.
