This is the first I've heard of this. I have witnessed our staff at |
| 13 |
working plugging something in and having static discharge fry a USB |
| 14 |
stick, but I've never seen that happen while unplugging. |

I tell staff to touch the computer case before plugging it in first. |

When a user fries one I asked if they touched the case first and the |
| 18 |
answer is always "no". |
