Thanks very much for the response. I agree this is very odd.
Alongwith a local associate I checked the issue as thoroughly as possible
and found that the issue may be with Power Management settings. For reasons
as yet unexplainable, the AU and BITS services were interfering with
bus-powered USB devices.
The Verizon PC5220 AirCard Wireless Modem is a CardBus device but is
installed as a (virtual?) composite USB device with the Lucent Open Host
Controller installed in the process. Thus, the modem shows as a USB device
whether it is installed on a laptop (which is was primarily designed for) or
through a CardBus-PCI adapter as is the case with the Server 2003 desktop
machine I am working on. This might be to enable it to draw power for its
working.
On the suggestion of my friend, I switched off the Internet connection and
turned on the AU and BITS services. Then, we tried to install software - in
this instance QuickTime and then Lavasoft AdAware. In each instance, the
modem would repeat the eject-reinsert behavior! Now this was happening even
with the PC offline.
The PC was shut down and restarted after turning off power management in the
BIOS. The behavior repeated itself. Further, all USB ports had the option of
enabling power to be switched off to conserve power usage, switched off. But
to no avail. The CardBus-PCI adapter was switched to a different PCI slot to
see if there was any change. No.
Just by way of interest, the wireless modem was unplugged and totally
uninstalled. A standard CardBus Wi-Fi card was installed in its place. The
behavior repeated there too!
Since the issue only happens with the wireless modem and it is not what is
normally used on the machine when it is in regular use, we decided not to
attend to this problem any further. The modem and associated drivers will be
uninstalled when the PC is returned to its user anyway in a few weeks. The
user will be informaed of what happened - but this is unlikely to hamper
operations in any way when the PC goes back to regular use.
The wireless modem was installed for Internet browsing only actually. The
update operation was first tried only when last Tuesday rolled around.
Two further weird findings on this PC:
1. The Verizon wireless broadband service advertises burst speeds of up to
2Mbps with averages of around 400 to 700 kbps. This Server machine averages
around 800 kbps most times. My own laptop and desktop averages 500 kpbs in
the same location.
2. Windows Media Player 10 is on this PC. I thought WMP 10 was only for XP
and Media Center Edition. In fact WMP 10 cannot be installed on a Server
apparently (I tried on a different Server 2003 PC). I will have to wait to
ask the user/owner how it got on. I had built the machine originally and did
the initial OS install and did not add WMP 10 on it!
Thanks very much for your helpful suggestions. I will let the user/owner
file a support if desired when this machine is returned to him. One hope
this does not signal a more serious malfunction eleweher on the system
