Funnily enough I also had some weird USB happenings in the last 24 hours.
I was working away yesterday when I got the ding-dong note to say a USB
device had disconnected. This sometimes happens with the iPAQ if it isn't on
the cradle properly so I ignored it. A few seconds later a dong-ding
indicated that it had reconnected. About 20 minutes later it happened again
but then became persistent, ding-dong, dong-ding, ding-dong, dong-ding,
ding-dong, dong-ding, ding-dong, dong-ding. Annoying!
I took the iPAQ from the cradle but the noise continued - and here you hit a
problem because XP doesn't identify the USB device other than to say "USB
Device" - not very helpful as I have 21 of the things plugged into the PC.
As I slowly started working round the cables it then went into a cascade
failure and all the Go Flight units fell offline and I started to get "USB
Failure" warnings. A quick check of Device Manager then showed ten unknown
devices.
Rather than fiddle with loads of plugs and hubs I suspected the fault may be
elsewhere so I rebooted XP and everything came back to normal. I still don't
know what the problem was but it could have been one of several things.
First, I'd just installed .NET 3.5 on the system and it didn't install
cleanly - it took two goes to get it working. The failures occurred during
that time (weird but feasible knowing XP). Second was that I was testing
software that was running the CPU at 100% so maybe the power to the USB
sockets dipped and caused the devices to fail through lack or juice.
Alternatively the mobo may have thrown a wobbler and likewise wasn't feeding
the USB ports with enough power.
Although I use 21 devices here few need a significant load - only two
require the maximum 500mA for a socket. The three hubs I have are all
powered so it allows me 500mA per socket rather than for all seven sockets
for the hub - very handy. I know what each device draws as this is shown in
Device Manager somewhere. The toughest one is the SBS unit as this is fed
from a 15m cable running up to the roof through a powered USB extender.
Since the reboot everything is back to normal so I'll never know what caused
the whole lot to fall over..

I think it may have been Mike who, a couple of days ago, had to re
allocate functions after pulling USB connections. It must be infectious!
I'd had a couple of odd results when pressing a GoFlight button and it
became clear it was because the 7 Port USB1 Hub into which that GF
connected had gone u/s. It's been running since USB was invented!
After nipping down to the shops for a new unit I started to plug in. At
which point I found the 4 of the5 units and Rudder Pedals were now
sporting the wrong functions. I thought it would be simply a matter of
trying them in various positions, until I hit the original function
allocation. In FS9 it is. GF's modified for FSX GFConfig doesn't seem to
re allocate on the fly, so I've had to programme them all over again,
from scratch. This time I'll mark the slot allocation on the Hub...I
seem to remember having similar sensible ideas in the past but I still
manage to drop into deep doggy do!
