Hi!

When I connect my Display Link Adapter to the USB hub, where my Apple USB Ethernet Adapter is also connected to, the ethernet disappears... Any chance this bug in the Display Link driver get fixed soon?

My system is a 11" Mac Book Air with Mac OX 10.6.5 and Display Link 1.6b3 running.

Seconding Pascal's prompt about this problem ...

The problem appeared in the DisplayLink 1.5 driver series, and seems to have something to do with the DisplayLink driver enumerating all the USB devices on the system when loading, which causes a call into the ASIX drivers (AppleUSBEthernet) that it doesn't expect. This causes the ASIX driver to go into a "disconnected" state, which only a unload/reload of the driver will fix.

There are some workarounds, but they're ugly: http://plugable.com/2010/06/16/workaround-for-mac-os-x-conflicts-between-displaylink-and-usb-ethernet/

Any updates from the DisplayLink side on this problem?

Best wishes and thanks!
