Dear list,
I am trying to identify a USB related hardware
fault/instability on a few of our ultrasound machines.
Question: what known misbehaviours do exist for
a USB device on a given root hub port to affect other USB hardware
connected to other root hub ports? (cause it to become disabled etc)
Now to my problem:
One particular machine is known to lose USB peripherals from time to time.
(from none per day up to several times per day, it does not matter if the
machine is
idle or not - USB wise)
Under WinXP (the normal operating environment, I am not responsible for
using this OS :-) some USB peripherals simply disappear and occasionally
re-appear if one is lucky enough.
No traces in the event log of course.
The PC is intel P4 3.2 GHz, 2GB ram, ICH6 chip seet, pls see USB topology
below. (output of
modified usbtree perl script)

In order to get some diagnostic output I compiled a linux kernel (2.6.16.11)
with usb debugging enabled.
Then I started a test sequence of 1.5 hrs power on and then 0.5 hrs power off.
One such testing sequence started at Jul 2 23:00:00 (11:00 PM)
Nothing happened until about 1 hour and 9 minutes later:
lots of output like this:

The following peripherals have been affected this time:
* everything connected to the 4 port hub on root hub P6
* USB printer on P7
* USB to IDE converter, pls see topolgy below.
After replacing the main board USB did not work at all. No peripheral
was detected. Unfortunately the keyboard was also USB.
Plugging in an additional USB keyboard did not work at any root hub port.
I removed everything one by one from the root hub ports then re-plugged
everything and all worked again.
Machine is currently running and I am waiting for the next incident.....
Question to the gurus: (Alan Stern included - it seems you missed my e-mail)
given the above log fragments (more available on request), what hardware
component might be responsible for this mess?
