Hey guys, My Macbook Pro seems to have some problems with certain usb devices. I have a flash drive which works just fine, but when I put it directly into my Mac, it will just not register. If I put a hub in the same usb port and put the flash drive in there, it will just work fine. I also just received my Wacom tablet today, and wired, it works great, but my Mac will just not see the wireless dongle. The dongle works just fine though (I tested it on another Mac and a Windows PC). Does anyone have an idea as to how I could fix this?
