Hi. Recently I've installed FreeBSD (RELEASE-5.4), and I cannot get my USB cable modem working. The problem is that cdce driver doesn't determine MAC address correctly. Here is a corresponding part of dmesg log (full log and other info is in the end of the message): cdce0: Motorola Corporation SB4200 USB Cable Modem, rev 1.00/1.01, addr 2 cdce0: faking MAC address cdce0: Ethernet address: 2a:00:00:00:00:00 cdce0: if_start running deferred for Giant I've also tried driver from 6.0-RC1, but result was the same. Despite I'm not familiar with programming drivers for freebsd, I've explore a code a bit, and determined, that the problem is in a following line (from /sys/dev/usb/if_cdce.c). ue = (const usb_cdc_ethernet_descriptor_t *)usb_find_desc(dev, UDESC_INTERFACE, UDESCSUB_CDC_ENF); The expression in the right part of assignment returns 0, but it should return a pointer to a structure. I've tried to look into CDCEther Linux driver, but I have no experience with system programming, and unfamiliar with device specifications, so comparison of drivers didn't help to determine why things go wrong. Any help would be greatly appreciated. uname -a FreeBSD vatutin.emacs.no-ip.org 5.4-RELEASE FreeBSD 5.4-RELEASE #0: Sat Oct 29 12:05:21 EEST 2005 root@vatutin.emacs.no-ip.org:/usr/src/sys/i386/compile/GENERIC i386 dmesg Copyright (c) 1992-2005 The FreeBSD Project.
