This is really challenging me... I don't think I've ever had such difficulty with a piece of HW under XP.
Trying to install a Multitech 128kb ISDN TA for one of my clients so that they can use banking software.
It's a USB device.
What could be simpler you ask?
Nothing happens upon plugging it in, i.e. no little balloon pops up to say "new device found". It doesn't show up in device manager.
There is no obvious sign that XP can see the TA at all.
HOWEVER - if you try to install it manually, it appears at the bottom of the hardware list - a sign that XP can see it's there. If you try to go ahead with the installation from there, it says it's already installed and working!! (if you unplug it, it vanishes from the list)
ALL of the dialups that used another TA (which has now been removed) have changed to dial up with the Multitech, even though it doesn't appear to be installed, or in device manager.
What's more frustrating is that a) all other USB devices on the machine work fine, and b) I can install this very TA on any other XP machine with no problem whatsoever.
Can anyone shine a ray of inspiration???
Sorry, Rant over.
BT are attempting to fix it, (their end apparently, so not a proper hw problem for me) but its bin 8 hours since i reported it
