The devices are PCI cards, no USB is involved. I assume that I'd have to add lines similar to hint.sis.0.at="pci0:9:0" to /boot/device.hints, but I am unsure of the correct syntax. See also these old articles (which ultimately seem to have gone unanswered): http://lists.freebsd.org/pipermail/freebsd-questions/2009-January/190453.html , http://lists.freebsd.org/pipermail/freebsd-questions/2009-January/190624.html -- Martin On 12/30/14 21:13, Freddie Cash wrote: > > On Dec 30, 2014 10:02 AM, "Martin Birgmeier" <la5lbtyi@aon.at > <mailto:la5lbtyi@aon.at>> wrote: > > > > Hi, > > > > I have two network interfaces as follows: > > > > sis0: <NatSemi DP8381[56] 10/100BaseTX> port 0xa400-0xa4ff mem > > 0xd5800000-0xd5800fff irq 9 at device 9.0 on pci0 > > sis1: <NatSemi DP8381[56] 10/100BaseTX> port 0x9400-0x94ff mem > > 0xd4800000-0xd4800fff irq 11 at device 12.0 on pci0 > > > > When sis0 breaks down, sis1 gets renumbered as sis0, wreaking havoc > > (mostly on my brains until I figure out which card is actually > affected). > > > > How do I tie down these two interfaces so that they always stay as sis0 > > and sis1, respectively, regardless of which ones are present in the > > system? - I expect to insert something into /boot/device.hints. > > There was a recent thread on one of the lists about using devd to name > USB Ethernet devices based on their MAC or serial number.
