Re: does OS 10.4.7 support CDC Ethernet Emulation Model now?

Brendon,
This is a CDC Abstract Control Model (ACM) and an Ethernet Control Model (ECM) device. The subclass field, in interface 0, is 2 (ACM), however the protocol field is vendor specific (255) which will cause the current ACM driver to fail. This has been fixed but not released yet. The subclass field, in interface 1, is 6 (ECM) and should work with the currently released Apple CDC driver.

Sure thanks for the info.  I also think I might have figured this out and gotten it to work as a ECM but would still be curious if it is indeed a control model device

Also sorry for the newbie question but which one of the fields below will tell me that.

thanks again for all your help

Brendon

Brendon,
If the device works with the older USBCDCEthernet driver then it's an Ethernet Control Model (ECM) not an Ethernet Emulation Model (EEM) device. If that's the case it should work with Apple's released CDC driver.

Could you include a USB Bus probe so we can confirm exactly what the device is.

Thanks...
Russ
