I'm having an odd problem with my Toshiba Satellite L300 portable with Vista 32 installed.
I think this may have started when I tried to plug in a Motorola cell phone. The driver installation failed and the phone connection never worked, not unusual for Motorola. I think it was around this time that the Logitech wireless mouse stopped working. I noticed also that I would get a message every few minutes that said, "USB Device Not Recognized - One of the USB devices attached to the computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message"
I unplugged the USB wireless mouse device, which was the only USB port being used.
The message continued to return, eventhough there were no USB devices plugged in.
This is where it gets weird.
I then reformatted the computer and let it reinstall Vista 32, returning it to "Out of Box" state. All during the lenghty Windows update process, I was surprised to see that message still appearing every few minutes even though there were still no usb devices attached.
I tried plugging the USB wireless mouse into another computer and it worked fine.
I also tried plugging a few other USB flash memory devices into the Toshiba portable and they all worked fine too.A Logitech webcam worked fine. A Microsoft wired USB mouse failed to work, however. Same message as with the wireless mouse. It seems that anything other than a wired or wireless mouse works OK.
There are three USB ports on the computer and all of them produce the same results.
So, the two issues that I now have are:
1. It is only the Logitech wireless usb mouse that fails to work on the Toshiba and only on the Toshiba.
2. Plus that aggravating message continues to pop up every few minutes, even when no USB devices are attached.
In Device Manager +USB Controllers there are 8 entries that say something like "Intel ICH9 Family USB Universal Host Controller" and 8 more entries that say "USB Root Hub". Why so many, I don't know. When I plug in the mouse, I get the hated Message about USB Device not recognized, the same one that comes up on its own every now and then. When this happens there is another entry that falls between the first eight and the last eight entries for USB Controllers. It says "Unknown Device."
I also uninstalled all 16 entries in the USB Controllers section of Device Manager and let them reinstall themselves. That did nothing to resolve this.
I'm stumped and open to suggestions or advice. I really miss my wireless mouse.
