USB works but unfortunately my lamp will not turn on. I’ve tried different bulbs but nothing. Edit I have the lamp packed and ready to go l, but 3 years ago I returned a desk that was broken during shipping. I also ordered two little rugs in April of last year  that were very cheaply made and disappointing. Apparently that means I need a specialized team to make a simple return. I will never shop on Wayfair again. I’m tired of being disappointed with shoddy merchandise. Marcia, the person I chatted with online rudely closed the conversation. Never again
