This is likely a Davicom DM9601 based adapter. At least the Linux driver dm9601 lists the vendor and device id you mentioned in the source: =linux/kernel/git/torvalds/linux.git;a=blob_plain;f=drivers/net/usb/dm9601.c;hb=HEAD
Since this chip seems to be rather old (according to the kernel source USB 1.1, so no Hi-Speed mode), I doubt there is any Windows driver for x64 systems. At least Davicom itself does not offer x64 drivers while they have x86 drivers: =209814 - So just hacking inf (as it often helps, if just vendor or device ids do not match) will not help.
so I was in the same boat and finally managed to find a way to make the damn USB adapter work :) I downloaded and installed the Davicom drivers for Win 7 that Gurken Papst mentioned. I know they're not supposed to be the exact thing, but apparently the adapter didn't mind much. Had to manually assign them in the device manager, but other than that it was smooth sailing. Thought I'd share, since so many people seem to be having trouble with this.
We understand you're having some issues looking for drivers for this third-party accessory. In this case, your best bet would be to contact the manufacturer of this USB accessory or the vendor who sold it to you originally. They'd be in the best position to support the products they have created. Otherwise, you'd want to use an officially supported one from Apple or another certified accessory manufacturer. 1e1e36bf2d
