Here are some things that might be problems: o The DE-600 driver will only work the first time after powering up the machine. After that, it doesn't recognize the existance of the adapter. o There is more than one product called the DEPCA. The enclosed packet driver only works on the newer boards. See DEPCA.NOT for details. o Several people reported that the 7.x 3c505 driver didn't work. Then again, one person reported that it *did* work. o The 8.x driver ignores that class of your driver when your application asks for all packets regardless of type. This is very unlikely to cause problems, but should be documented anyway.
