Thanks for the input. I have the latest drivers but it seems that there
is some serious incompatibility issue with the kernel as when the
FLASHING happens even if the system is restarted it's still not
detected. One has to re-plug it in and then it shows in "wanrouter hwprobe".
It could also be that the atom board is not compatible with the driver
in my case. It your /var/log/messages upon restart do you any line that
might match this:
*
*
*cd /var/log/*
*grep -o "device not accepting address" **
*grep -o "USB device is disconnected" **
*dmesg | egrep "device not accepting address" *
*dmesg | egrep "USB device is disconnected" *
If not then you are not experiencing the same issue. If you have then
it's a universal issue and not hardware specific.
I would really appreciate it if you look into your logs and let me know.
If you are asking me to look into the logs when the U100 is not
recognised and it is flashing - I'm afraid I can't help much - as this
problem went away and haven't had issues any more for at least 6-8
months now. Considering the U100 persist in giving problems even after
computer restarts somehow sounds to me like a hardware issue. I wouldn't
be surprised if the Acer Aspire motherboard is not coping very well with
both of them being plugged in - although, obviously, it should.
This linux-usb FAQ seems to also suggest that the problem is hardware
(based on the "device is not accepting address" error message):
http://www.linux-usb.org/FAQ.html#ts6
Have you tried disabling in bios everything you don't use - maybe sound
card, wifi etc. to free some IRQ's?
I run kernel 2.6.33.4-smp - just in case it helps.
Let me know if you need any other info. If you find a final solution - I
would be curious to know - just in case I will stumble over this problem.
It wouldn't be a bad idea to build a script which grep's lsusb output -
and run it through cron maybe every 10 minutes - to try and determine
more precisely when does the U100 stop being recognised. Then you can
look through the logs to see if there is anything else happening in the
system around the same time.

Hi Bruce,

Thanks for the input. I can not replicate the situation as it
happens
randomely or maybe over the weekend. However I have sent you all the
requested command and logs in a separate e-mail for your
analyzes. The
only thing that stood out at me was the output of "lsusb -v" at
the very
end where it timed out.
Since all lines didn't work I am to assume that both module went
down
but per my diagnoses with "hwprobe" I could see one unit
connected and
the other was not when the problem happened. Simply
connecting/disconnecting that unit or connecting it to another port
solved the problem and it showed up in "hwprobe"
This is an Acer Aspire Revo mini PC. I am wondering if the U100s
draw
too much power? The only other USB connected device is the thumb
size
wireless connector for the keyboard.

Don't know if this will help - but I will butt in with what I have :-)
I've been using a Sangoma U100 adapter for about 2 years now. It is
connected to a Compaq V2120 laptop (Celeron M 1.4GHz processor)
which serves as my home server. It is actually the main reason I
went for the U100 - as I couldn't add a PCI or PCIe card to a laptop
to get the FXO ports I needed. I have to say I really like the U100
- I believe it is the only low(ish) cost USB based FXO interface on
the market.
I have had occasional problems with it. I remember it used to just
stop working - and the lights would start flashing. If I remember
correctly - I went to Sangoma's website and downloaded the latest
wanpipe drivers, compiled and installed them - and everything was ok
after that. At the moment I'm running Asterisk 1.6.2.9 and wanpipe
3.5.11. I can't remember what version of wanpipe was giving
problems, I'm afraid.
I also found that mine doesn't really like to be hot-plugged - it
just freezes the system with strange characters on the screen. But
that was a while ago. Since I've learned it's foibles - it must be
at least one year since I had to look at it.

Looking forward to your analysis.

Bruce

or lspci?).
Hi Bruce,
The following would be useful for starters:
1. cat /etc/wanpipe/*.conf
2. ifconfig -a (from a working and non-working situation)
3. lspci -v and lsusb -v (from a working and non-working
situation)
4. wanrouter hwprobe verbose (from a working and non-working
situation)
5. /var/log/messages (near the date the problem happened)
