ASIX AX88772 USB to Ethernet

Will the ASIX AX88772A USB to Ethernet adapter work with xPC target or is this different than the ASIX AX88772??

Thank you

Often an "A" suffix on a part indicates a design fix or a firmware fix or a chip remaster (e.g., narrower tracks.) It is not _often_ that an "A" suffix indicates an incompatible part -- *usually* an "A" part is a drop-in replacement.

But that's a generality.

Perfect, thank you.

On checking, I see they are different devices that announce themselves with different product IDs. The two devices are also packaged differently (the non-A is 128 pin, the -A is 64 pin). The non-A supports USB 1.0, 1.1, 2.0, but the -A supports USB 1.1, 2.0. You should be able to feed a single 3.3V supply for both.

Thank you for checking this Walter, however I received my adapter today and it does not work with the xPC kernel. It seems to be that the USB adapter is not receiving any power in the xPC kernel because the LED's on the adapter are not lit and a "Network cable Unplugged" is showing on the host side... I have tested the adapter in Windows 7 on the xPC Target and it works fine showing proper connection on host side, however when I load the xPC Target kernel it does not work... Any ideas?

The part number you gave is a chip, not a board. Which board are you using?

- Purchased on ebay and installs the ASIX AX88772A driver.. I have no other information about this adpater.

To check: are you using R2011b or later?

[Robert]

I am using R2011b at the moment but can use R2012a if needed.
