Ok, started having this problem yesterday after Windows Update did its job. Now my mouse won’t work, and the IdeaCom HID Touch Screen is what’s disabling it. I don’t have a tablet PC, so why Vista installed this, I’m not entirely sure. Ugh. Vista won’t give me the option to disable the driver, either. Why it disables the touchpad, I have no idea. Boy, that’s annoying!
So, to get my TouchPad back "permanently", I did the following:
- Go to Start menu, select Computer, and use the "menu" key on to select Manage. The Menu key is usually to the right of the space bar, and looks like a menu with a mouse pointer.
- I used my arrow keys to select Device Manager and Tabbed over to Devices.
- I selected Human Interface Devices, and there was the IdeaCom driver. I used the Menu key on it and selected Uninstall Driver. Make sure you check the delete driver checkbox when prompted!
- I restarted my computer as Vista commanded.
- After restarting, Vista reinstalled my Dell Touchpad driver. Again, I had to restart.
- Vista came back up and all was happy again in Auriville.
Note: I have Vista 64-bit, Service Pack 1. Amount of memory and hard drive space doesn’t matter.
