Sounds like your modem script doesnt properly initialize, or hang up from a previous connection. Are you using a modem script provided by the manufacturer, or one you wrote?

I don't know but presume it's the modem script provided as i wouldn't know how to write one.  I'm a designer and illustrtor so my talents are elswhere. When I set it up I used the System Preferences > Network and filled in the blanks with the Service Provider on the phone.  Where do I look to see?  I use the phone while the unit is sleeping so I would presume it has hung up.

In your Network control panel you have a tab for the modem settings, including the script. I suspect you dont have the right modem script selected. Just because you can use the phone doesnt mean the modem has gracefully disconnected.

have you checked your settings in
system preferences
   energy saver
      options tab (3rd tab on right)

make sure that both Wake Options have been checked off
  1) Wake when the modem detects a ring
  2) Wake for Ethernet network administrator access

I have done all of the above.  i put it to sleep while I was out of the studio for about 5 hours.  When I woke it up, the modem wouldn't work as per the original problem.  I then rebooted and the modem worked.  I put it to sleep and about 15 minutes later it won't wake up.  I have been using a Mac for about 15 years and this is the most constantly annoying unit i have had.

Ok, so you have an HFC USB modem, and are using the Apple Internal 56k modem script. Clearly not the right script for that modem. Any reason youre not using the internal 56k modem which would be the right modem to use with that script? Or alternatively, why arent you using the HFC modem script which would be the right script to use with that modem?

When I go to System Preferences > Network > Modem (tab) > Modem (flyout menu) there are no listings for HFC or MicroDash.
The listings that look the closest are:
Apple Internal 56K Modem (v.90) and Apple Internal 56K Modem (v.92).
In the System Profile V.92 and V.90 both show up and I have tried both and the problem persists as indicated.  Below is the information from the System Profile.  I don't know where else to look for a reference.  Thanks for your patience.

System Profile > USB Bus > Apple internal modem:
Apple internal modem:
Vendor Name: HCF USB V.90 Data/Fax Modem
Product ID: 33282 ($8202)

Apple Internal 56k Modem is nowhere close to HFC USB modem. You need to find or create a modem script for that particular modem. I'd suggest contacting the manufacturer.

I guess I'm astonished the unit was shipped w/o the script to match the modem supplied.  I'll contact the supplier and be back.  Thanks.

It appears that the problem has nothing to do with the modem.  In frustration I contacted our local Mac guru.  His first question was "Do you have a Belkin hub? Throw it away." He recommended Dr. Bott hubs and have one on order.  I disconnected all USB devices and the problem went away.  When I contacted Belkin tech support I basically got unplug and try one at a time.  I did and as soon as I added an item the problem returned.  I'm told Mac OS X power management is sensitive to malfunctions in USB devices, and to USB devices which do not recognize power management commands. I have a Belkin 4 port hub and several posts on the Apple forums note issues with Belkin cables and hubs

Youre still going to need an appropriate modem script.

When I search for HCF USB Modem V.90 I get Rockwell/Conexant and a lot of Windows information, no Mac.  I used a site called DriverGuide and got Windows info but no Mac.  When I search for MicroDash I get a lot of stuff about lighting.  Help!

Might have to write your own. There is an Apple Modem Script Generator floating around that you might find useful.

Found it.  It's called MSG for Mac OS X.  Haven't had time to figure it out.  I have talked to several other G5 owners who either don't need a USB hub or use a Dr. Bott hub and they have no problems.  I'll wait until I get the new hub and see if I need to learn how to write a script.  Thanks.
