[MacPro] 仲有無師兄用緊macbook pro 2012 mid (non-retina )

仲有無師兄用緊macbook pro 2012 mid (non-retina ),  我部機有問題,usb 3.0 插 cardreader  落去見到有card. 可以load 相,但load 到一半就停左. 後連卡都吾見左。(card reader, cf card. 都試左。無問題)。 上網爬過,好似都多人都有類似問題,試過插hd, 完全無反應。有無師兄都有類似情況?

本人用緊呢部, 無閣下呢個問題, 可能用左USB hub, 個Hub 係另插火牛拿電, 閣下呢個問可能係電力.

Got that problem a month ago, and I opened the back panel and use air-blower to clean the connection point. It works as usual.
Hope this helps
