I am working with a usb ethernet device and I am having 2 issues.
The driver has been supplied by the vender and I am using their private API to configure the device and make the connection to the network.
1)
Once my configuration and authentication exchange is done, the enX interface will get an IP address. If I type "ifconfig" in the terminal I can see that it has an IP address and a gateway address and I can ping the gateway IP address. If I then launch safari (or another internet application) I cannot make use of the interface until about 1 minute passes. After 1 minute I can browse normally and everything works.
What is causing this delay and is there anything I can do from my application to make the rest of the OS see the IP address that ifconfig sees?
2)
The 2nd issue is that if the current location has no ethernet service defined, my usb ethernet interface will never get an IP. The location can have an airport service with the airport turned off and I still get no IP address for my usb ethernet interface. If there is an ethernet service defined for the location and there is no cable connected to it, then I DO get an IP address on my usb ethernet interface. ifconfig never shows the usb ethernet interface as having an IP address.
This was first noticed on a MacBook Air, but we have replicated it on a MacBook and MacBook Pro as well.
I am thinking that it may be a dhcp issue, but that is just a wild guess at this point....
