After losing no small amount of work from this, I'm somewhat aggravated. I'm on Vista Business 32-bit on a Toshiba P300-011 business laptop, and occasionally all my USB ports stop responding, and Windows acts as if no USB devices are plugged in. When this happens, I have to restart my computer in order to get USB working, and if my computer attempts to enter standby mode, it will hang because the USB system isn't responding. There's no error reported, so windows still behaves as if USB is in fact working.
Is this a known problem at all, and if it is, what solutions are available?
