I have just rebooted the server and can confirm that neither dmesg, /var/log/messages or /var/log/syslog contain "device not accepting address" or "USB device is disconnected" error messages.<br>

don't have it then it's I guess very specific to this atom board. I<br>
know someone else added something along the lines "irq=fixconflict" to<br>
get rid of the issue with a wireless USB mouse showing same symptoms and<br>
CentOS. IRQ conflicts is also one of my thoughts as well but I can't<br>
play at BIOS level at this time as the server is thousands miles away<br>

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

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

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

I appreciate your feedback and let me know what<br>
info I<br>
can post<br>
here that may help resolve the issue (such as output<br>
from dmesg<br>
or lspci?).<br>
<br>
<br>
Hi Bruce,<br>
<br>
The following would be useful for starters:<br>
<br>
1. cat /etc/wanpipe/*.conf<br>
<br>
2. ifconfig -a (from a working and non-working<br>
situation)<br>
<br>
3. lspci -v and lsusb -v (from a working and non-working<br>
situation)<br>
<br>
4. wanrouter hwprobe verbose (from a working and<br>
non-working<br>
situation)<br>
<br>
5. /var/log/messages (near the date the problem<br>
happened)<br>
