I have a NetComm 56k V.92 modem, that uses the 1648c-TV5 & 1034S chipset, installed on XP Pro SP1.
When the ISP modem drops the call, my WinXP mouse curser freezes for a few seconds, then unfeezes, then freezes for a few more seconds, then unfreezes and returns to normal.
Is this normal behaviour for the Agere modem ?
Anyone know why this happens ?
Is it because the PCI modem is sharing some resource with the mouse, if so why does it only manifest when the remote modem hangs up ?
Is the modem doing something on the PCI bus to momentarily freeze the whole PC, not just the mouse, but I can only get direct evidence of the freeze via the mouse / curser freezing ?

It is the nature of the design/driver that when the modem [virtual] port is opened or closed to cause a momentary free of the mouse. On "normal" systems, this will be brief - less than a second.
Multiple freezes each lasting more than a second is sign of either a very underpowered or out-of-tune PC.
How much RAM do you have? What type/speed processor?
How many processes does task manager show running right after you boot up and before you do anything else?(to run task mgr - press ctrl+alt+del then click task manager, click the processes tab, and the total # of processes is displayed in the bottom left corner of the task mgr window.)

Aloha! Richard.

Its a 2.4GHz Celeron with 512Mb of ram. I'm using Win XP Pro SP1. The momentary freezing when the ISP modem disconnects happens even if I close down all the running process before the session times out, but now you mention it, the freezing may be more noticable when I'm running Firefox browser with 96 tabs open, Limewire Peer to Peer downloading / uploading and Net Transport download manager downloading several binaries, simultaneously. Even with all these apps running, task manager still shows system idle at 40% cpu.

I was really trying to confirm that I don't have some kind of incorrect setting somewhere causing a resource conflict. I was thinking along these lines. Because when I installed the modem drivers, using the LTRemove.exe then Setup.exe procedure, Win XP pops up several little information balloons in the task tray which mention the USB Hub and some other things and finally a balloon mentions the modem.
I don't understand why XP would appear to be changing the USB hardware or drivers when all I did was remove and install the PCI modem drivers ?
My mouse happens to be a Microsoft Optical USB type.
These bits of info. seem to point to some kind of interaction.

LTRemove may affect more than the LT modem, but this shouldn't be a problem. [There are some USB-based LT modems and ltremove was designed to take care of them as well.)

Aloha! Richard.
