When this is happening, the red LED on the PI itself flashing in time with the power to the keyboard (that is, when the keyboard turns off, the light flashes.) So I have a Raspberry Pi B+ - I've had it for several years now, which I think may be the cause of this problem, though I'm not sure how.īasically, it's fine when I have just a keyboard plugged in, albeit a bit slow, and likewise when I have a keyboard and mouse plugged in, but when I plug in my USB network adapter a little lightning bolt symbol flashes at the top right of the monitor, and power to the keyboard is repeatedly cut off, then turns back on, then gets cut off again, and so on.
