Hi all

I have a problem with USB ports on my mother card. My computer is connected
to ADSL via an USB modem. If i plug in an other USB product (like an
external hard drive or DVD writer) , everything works fine the first time.
But some times later (after hours ) my USB modem shut down even if the other
USB product is disconnected. It seems like the USB ports can't provide any
power to USB.

What can be the problem? Is there a solution? Any suggestions? Thanks for
your answers... (excuse me for my bad english)

See "USB Device Stops Working or Won't Resume", about half way
down on this page. WinXP can turn off power to a port, as part of
power management. Uncheck the box as shown here:

A second reason may be hardware related. Some USB ADSL modems,
like the Alcatel 330 modem, draw slightly more than 500mA
of current. Some motherboards detect this as an overload
and turn off the port. One solution is to use a self powered
hub (i.e. an external hub that has its own power supply).
A second solution is to complain to your ISP, and get an
Ethernet connected modem. I would never accept a USB modem
for this application, and am currently using an Ethernet
version, as Ethernet is much more robust.

A third reason, is some chipsets just have badly implemented
USB interfaces. Sometimes, using a plugin PCI USB card can
give you some relief. A search of Google might help identify
a good product (i.e. see a product at your computer store,
then search Google using the model name and number, to see
if others find the card acceptable).

If none of this is working for you, the cheapest solution is
to see if your ISP has an alternate (Ethernet based)
modem for you to use.

Paul is very right.

USB modems usually are a headache at best, and they choke down your speed.
Get a NIC (ethernet card), install it, buy a router (you don't have to, but
they are cheap now and offer many advantages, and get an ethernet modem.
In fact, many modems come equiped to do either USB and/or eithernet.

Ethernet is so much way better, and if you get a router, you can add more
computers and share the connection (this won't violate your contract if you
use something like 2, 3, or 4 computers.

Also, with ethernet you can go with Voice Over IP Telephony, which you can
get for a great price, right now Vonage is only $25 a month. Get that and
a cell phone and who needs a regular telephone line? And the box also
plugs into a router. Routers usually come equiped with 4 ports for devices
via network cable.

Here in Ithaca, the technicians strongly recommend against using USB as the
hookup on cable broadband.

Just FWIW

But the OPs problem will be, in Europe they tend to a
"take it or leave it" attitude. Sometimes the only option
offered, is that stinking USB modem. And with limited telecom
competition, you cannot escape by looking for another ISP.
I would have hoped all the Alcatel 330 modems would have been
buried in a hole in the ground by now :-) I hope that is not
the model involved here.
