Just got shiny new servers and shiny new Edgeports/416 yesterday. Installed Ubuntu Lucid (10.4 LTS) on the servers
Just plugging in the Edgeports manages to produce 4 of the 16 serial ports as /dev/ttyUSB0-3, which is a start. Unplugging and plugging back in makes all 16 appear. However, after a reboot, there are only 4 again. Since these are going to be installed remotely, without an easy way to unplug after a reboot, this is most annoying.
Is there a fix to this?
Thanks
Chris
Hello Chris,
What are the 50xxxxxx part numbers and revisions of the Edgeport/416 units in question?
How are these Edgeport/416 units connected to the PC? Are they connected directly to the PC or going through a USB hub or some other kind of extender device? Are any of the Edgeport/416 units daisy chained through each other?
Do all 16 ports ever get produced, or does this same problem happen 100% of the time where only 4 ports get produced?
Hi Jeremy,
from the label underneath:
PN: (1P) 50001359-01 C - they’re the DB9 variants
They’re connected directly into the PC (server), no hubs, no daisy chaining - we’ve got 2, one each for each server
I get varying numbers of ports… currently sitting at 10, however I have had all 16, but haven’t consistently managed to get them all 
I get firmware upload errors when ports fail - I can post detailed logs if it would be useful. But I’ve tried various different versions of down3.bin to no avail
Many thanks
Chris
Yes, please post those lots.
logs, even.
Hi jeremy,
Attached are the logs produced when I unplugged the 416, then plugged it back in - I’ve ended up with 10 ports active…
Hi Jeremy
Another sample - I rebooted the machine with the edgeport unplugged, then, after removing power to it, plugged it back into the power, then the usb.
Thanks
Chris
oh - just 4 ports active after this
Chris
Chris,
Are you using the kernel provided with Ubuntu or a vanilla 2.6.35 kernel?
I will try to re-create this issue and get back with you ASAP.
Jeremy: Thanks!
userid0: using ubuntu kernels - I tried the latest one from Maverick to see if it made any difference (which is what I did the tests with), but I get the same behaviour with the latest Lucid kernel (2.6.32, IIRC).
I haven’t yet been able to re-produce this but I did some more research and this issue has been reported to us before.
Try updating the Edgeport firmware by following these instructions:
www.brimson.com/downloads/down3.bin.5.32.0
cd /lib/firmware/edgeport
mv down3.bin down3.bin.orig
mv down3.bin.5.3.0 down3.bin
chmod 777 down3.bin
You may need to unplug/replug the Edgeport/416 afterwards.
Does this help?
Hi Jeremy,
I’ve downloaded the firmware, removed power and usb and rebooted, but still the same behaviour. Did manage to get 6 ports recognised at one point, but then, I have got that before.
I’ve also tried daisy chaining them via the onboard usb hub, and, I don’t know if this provides any clues but, none of them worked to start with. Then unplugged/plugged at the computer end, and 8 started working. had to unplug/plug at the hub side to get all 16 working.

Thanks

Just tried it on another random Linux machine here in the office - completely different hardware (AMD processor, nNvidia chipset) and got exactly the same behaviour. Also tried putting a cheap USB hub in between too.
What are you using to try to reproduce this?
Thanks
Chris
OK, progress of a sort.
Spent a productive day installing various different Linux versions to see what works and what doesn’t.
Tried Ubuntu back to Hardy (8.04). Everything after 8.04 doesn’t work, 8.04 works.
I’ve also tried Centos 5.5 and pjtsubaru’s method to get 2.6.18 working and that’s fine too.
versions:
ubuntu 8.04 is kernel 2.6.24-26 and does work
ubuntu 9.10 is kernel 2.6.27-17 and doesn’t work.
I’m currently compiling a vanilla kernel off kernel.org to see if that’s broken or if its an ubuntu specific problem.
Just for a bit of variety, tried Fedora which also doesn’t work, kernel version 2.6.33.3-85.fc13.x86_64 - not an ubuntu specific problem by the looks of things
Looks like it’s possibly related to the kernel version:
http://kerneltrap.org/mailarchive/linux-usb/2009/10/8/6253517
Have you tried the latest stable vanilla kernel (2.6.35)?
The bug which the patch applies to has been fixed in the current kernel tree - I hit that on one of my Ubuntu installs - it was I think 9.10 - the CD install kernel didn’t load the edgeport driver at all and stopped with a Null pointer deference as per:
http://article.gmane.org/gmane.linux.usb.general/22946/match=2.6.31.2+io_ti
However, the second part of his post here is exactly what I’m seeing!

latest vanilla kernel still compiling! I don’t remember it taking quite this long back in the day 
CHris
Vanilla 2.6.35 compiled, still no improvement
