I have done searches and read through many USB related threads. Found nothing related to my problem.
I use 2 PCs daily. The notebook runs on Win XP and the desktop (7 month old from purchase) runs on Vista Home Premium.
Several USB devices (desk-top hard drives, SD cards, digital camera etc) functioned normally previous are no longer recognized by the Vista PC now. All these devices still work with the XP notebook. I checked all the usual suspects to no avail, such as loose cables, power-on-off and so forth. I suspect that it might be due to corrupted device driver. Worth noting is that I have one external USB hard drive (the only one) still works with the Vista. This blows the bad driver theory out the window, no?
The 3 external hard drives (one works and 2 don’t with Vista; all work with XP) that I use daily, all are from Iomega. Iomega claims that it does not have any driver for download since it depends on the OS to supply.
Also note that I have at least 6 available USB ports on the Vista PC and LCD Monitor combined. I had tried switching ports. Results same.
Appreciate any help to get these devices up and running again. Thanks.
