>Description:
The ASIX AX88772A USB 2.0 Ethernet chip has replaced the ASIC AX88772. Unlike
the original, it doesn't tend to corrupt its buffers. I just bought about a
dozen inexpensive USB Ethernet adapters that use this chip, and discovered to
my dismay that though there was driver support (axe(4)) for the older version,
the driver would not recognize the newer one. I managed to get it working by
patching two files. Please incorporate the changes into the tree.
>How-To-Repeat:
Plug in a Sabrent (or similar) USB Ethernet adapter based on the AX88772A.
FreeBSD 8.0-RELEASE won't recognize it.
>Fix:
Patch file attached. I also recommend including
options USB_VERBOSE
in the GENERIC kernel configuration (it is not there currently). Otherwise, the
vendor and device names won't be printed in the boot messages.
Patch attached with submission follows:
