I have a July 2011 15" MBP 2.2Ghz with 750GB 5400 rpm hard drive and 8 GB 1600 MHz ram configuration. I travel a lot and end up using both USB ports a lot for charging various devices (iPhone, iPad, chargers for iPhone and iPad, GoPro cameras, etc). I only use the Thunderbolt port at home when connected to my Thunderbolt Display and because the Ethernet now comes through the TB port, I rarely use the Ethernet port now too. I've NEVER used the FireWire800 port and would love to be able to adapt it somehow to USB2.0. I'm wondering if Apple or a 3rd party makes a reliable adapter so I can have 3 or more USB2.0 ports that I can use for charging... or better yet, perhaps a TB to USB3.0 port that I can use for both charging and a USB3.0 external drive. To summarize, these are the 3 adapters I'm searching for: FireWire800 to USB2.0 Ethernet to USB2.0 Thunderbolt to USB2.0 or USB3.0 Thank you!
