Home appliance interferes with USB hub
by lucmove from LinuxQuestions.org on (#5NFBA)
It's hot in here so I have a fan on by my side a lot of the time. Its minimum speed is too strong so I get tired of it after some time and I turn it off. Then I get hot again and I turn it on again later. In summary, it's turned on and off multiple times a day.
About two or three out of every ten times I turn it on or off, my mouse and keyboard stop working.
My mouse and keyboard share a USB hub that is connected to the computer. It is not a powered hub, so it's not connected to the mains. It's just connected to the computer's USB port.
So when I turn on/off the fan and the mouse and keyboard stop responding, the fix is to unplug them from the hub and plug them in again. That fix works every time.
My computer is connected to a UPS, but the fan is not. However, the UPS and the fan share the same power outlet extension. I like to believe that the UPS between the computer and the extension is enough separation to prevent the fan from interfering with the computer, but that is obviously not true.
So my question is, can I prevent this problem from occurring?
Maybe I could just get a separate extension for the fan, but I'm curious about people with knowledge of electrical installations might have to say about this. They're probably going to talk about grounding. Sigh. Proper grounding is not very common in my country...
TIA
