USB Device Problems when USB Wireless Network Connected

I recently installed a Belkin USB wireless network adaptor to my pc and
it works fine. The problem is that whenever the connection is enabled,
none of my other usb ports work. ie. an error message 'usb device not
recognised' is displayed. As soon as I disable the connection from the
system tray, and plug in the usb device again, it is recognised as
normal. I have windows xp home (SP2). Can anyone help??

Sounds like a USB 1.0 port on your computer. 1.0 will only support
one device per port. Are you using a USB hub? Is this by chance an
ancient PC with equally ancient USB ports?

It would also be helpful if you disclosed the model number of your
Belkin wireless device and verify that you have installed their latest
driver.

If possible, return the Belkin and get something else, or at least try
something else. It might well be a fault in the Belkin device or
driver.

Only if the implementation is badly broken. USB has supported multiple
devices per port from the get-go.

The primary difference between 1.0 and 1.1 was the addition of 12 Mbps
maximum speed ("full-speed" mode). 1.0 had a maximum speed of only 1.5
Mbps.

It's unlikely the computer is only 1.0 in any event -- very few 1.0
devices actually made it to market -- 1.1 was the earliest version with
wide support.

That said, there were lots of badly broken 1.1 implementations, both
hardware and software, which led to the unflattering moniker "Unusable
Serial Bus" as the true meaning of USB.

Yep. The problem is that I kept running into old hardware where the
supplied drivers would only support one device per port. The docs
accompanying the device warned that with a USB 1.0, only one USB
device could be "used" at a time. This was on an old Acer desktop and
printer. I don't recall the model numbers. When I plugged in another
USB device into a USB hub plugged into the one port, the printer port
hung. I've seen other such warnings about USB 1.0.

However, you're correct. I thought it was something inherent in the
USB 1.0 port. Apparently it's something in the device driver.

I've had to deal with old Acer and HP desktops that definitely came
with USB 1.0 ports. Neither are computers are available to determine
the model numbers.

It could also be something in the hardware. Not only was early hardware
pretty bad on its own, but also the 1.0 spec suffered from a number of
problems, particularly in the area of hubs. A big part of 1.1 was
fixing problems found in 1.0.

Thank guys. I had installed the windows 98 driver and not the xp
driver. Thats it. So now it is perfect. Thanks for the replies.

That was too easy. Couldn't you make the solution something more
exotic, weird, and in line with some of my weird and wild guesses(tm)?
I've got a reputation to maintain and you're not helping. Anyway,
congratulations on solving the problem and also somehow managing to
bypass the driver install version check, assuming Belkin actually has
one.

Which is the scary part.

What I've read (somewhere, can't now recall the source) is that USB 1.1 was
merely a "clarification" of the 1.0 spec, not an actual change. That isn't
correct?
