USB modem incompatibility?

By darah.shawn ·
Hello all, hoping I might find some resolution to an ongoing problem I've been dealing with for the past 5 months:

I am forced to use a USB modem for internet service (Pantech/UTStarcom UM175, if that matters any). The modem tends to work for a shot time, then behaves as if I have physically disconnected/reconnected. The only way to (temporarily) remedy it is to go through the motions of disconnect/reconnect. Once plugged back in, the cycle starts over.

I have checked for IRQ conflicts, PnP options in BIOS, and I have ensured that the USB Root Hubs aren't turning devices off to save power. Device Manager never shows any errors with the modem. If I check out Event Viewer, there are a couple error messages that pop up right when the modem goes through its seizure. I'll post them below.

I am running 64-bit XP, SP2 on this machine. If I take the modem to my laptop (32-bit Vista), I don't seem to have the problem so I'm leaning towards an incompatibility with 64-bit XP. Alltel technical support is unwilling to lend me any assistance, and I need to find a way to correct the problem.

Anyone have suggestions?

Have you tired this in different locations?

If the phone lines in your area are old, that could account for dropped calls.

Have you uninstalled and reinstalled the modem software?

Have you checked if there is a newer version available?

Have you tried a different USB port?

Does anything show up in the Event Viewer?

I've tried everything, it seems.

There are no phone lines - it's Wireless internet via Alltel that you dial into your specific #. I apologize if I didn't clarify that quite enough. My signal is also more than adequate, as 1) it works fine on the laptop and 2) I run it through an omnidirectional antenna with an amplifier.

Software and drivers have been uninstalled/reinstalled numerous times. That's about the point that Alltel techs gave up on me, as it apparently stretches the limits of their knowledge.

I've tried all 6 ports on the PC, and I also purchased a brand new card yesterday. Still the same thing.

The only things in Event Viewer are the two errors I posted above, unfortunately.

brand new card

by jdclyde In reply to I've tried everything, it ...

a USB card? That was going to be my next thing to look at.

Have you checked your BIOS? There could be a problem in there, that a flash of that could resolve.

Update your chipset drivers?

Remove the USB hub from the device manager, reboot and reinstall that, THEN reinstall the modem?

If it is working with the laptop, you know it isn't a problem with the wireless, it is your PC.

It's insane.

by darah.shawn In reply to brand new card

The odd thing is that all other devices on the USB cards work beautifully. I didn't think uninstalling the hubs would make any difference because of that?

I wish there were new chipset drivers or BIOS revisions...I'm pretty ****-retentive about keeping them up-to-date.

For a while, we thought the cards were bad...but I'm on my third card with the same issue. I've discussed it with users on an EVDO forum, and I've come across one other user with a similar issue. They also run a 64-bit OS.

If you have iTunes installed

by Jacky Howe In reply to USB modem incompatibility ...

try uninstalling it.

Okay, so...

by darah.shawn In reply to If you have iTunes instal ...

iTunes is uninstalled, as is anything related.

Still the same problem.

However, for kicks and giggles I thought I'd check my IRQ's again. 18 has me concerned...what do you think?

ISA 0 System timer
ISA 4 Communications Port (COM1)
ISA 6 Standard floppy disk controller
ISA 7 ECP Printer Port (LPT1)
ISA 8 System CMOS/real time clock

PCI 22 NVIDIA Network Bus Enumerator
PCI 22 Standard Enhanced PCI to USB Host Controller
PCI 23 NVIDIA nForce4 Serial ATA Controller

Am I staring at a conflict with the graphics card? If so, how do I remedy that? My option to "Change Setting" is all grayed out.

I don't think so

That is my OS, so we'll try it.

Let's hope that works. Thanks.
