The differences are summarized here: http://www.usb.org/developers/presentations/pres1108/SuperSpeed_USB_DevCon_C able_and_Connnector_Ling.pdf see pages 6-9 Of course this "should be perfected". However, quality of materials used in the connectors... plating, insulator, etc. etc. probably varies a good bit. I am using the cable that came with the Usb 3.0 3.5" hard drive enclosure for Sata Drives. This was one of the first ones on the market a few years ago, so I suspect that the mechanical specs of the connector were not done anywhere near the tolerance they should be, or it is just a crappy job. The connector is definitely too long and does not mate solidly. Here's more Usb 3.0 questions you were afraid to ask: http://blogs.msdn.com/b/usbcoreblog/archive/2012/06/27/how-to-determine-whet her-a-usb-3-0-device-is-operating-at-superspeed.aspx#_Use_USBView_to http://code.msdn.microsoft.com/windowshardware/USBView-sample-application-e3 241039 http://plugable.com/2012/12/01/windows-8-and-intel-usb-3-0-host-controllers <http://www.intel.com/p/en_US/support/highlights/sftwr-prod/usb3ehcd> http://www.intel.com/p/en_US/support/highlights/sftwr-prod/usb3ehcd <http://www.intel.com/support/chipsets/usb3/sb/CS-033977.htm> http://www.intel.com/support/chipsets/usb3/sb/CS-033977.htm <http://msdn.microsoft.com/en-us/library/windows/hardware/dn423379(v=vs.85). aspx> http://msdn.microsoft.com/en-us/library/windows/hardware/dn423379(v=vs.85).a spx <http://blogs.msdn.com/b/usbcoreblog/> http://blogs.msdn.com/b/usbcoreblog/ -----Original Message----- From: Tom Metro [mailto:[email protected]] Sent: Monday, February 10, 2014 4:11 PM To: Phil C.

Are USB 3.0 connectors mechanically different from 2.0 connectors? (From the pictures the "B" connectors do appear to be different.) If they're the same, shouldn't this be well perfected tech? If you have a cable that's not working well, I would just attribute that to bad luck and try the next low-cost, conveniently obtained alternative. Sadly cables are one of the items that retailers love to mark-up, often by several hundred percent. Best price is always found mail order, but then you're stuck buying a bunch in bulk to offset the shipping costs. As of yet I only own a USB 3.0 flash drive and thus haven't purchased any 3.0 cabling but I often buy cables from: <http://www.outletpc.com/cables-computer-cables-usb-cables-usb-3-0-a-to-b.ht ml> http://www.outletpc.com/cables-computer-cables-usb-cables-usb-3-0-a-to-b.htm l If price isn't an issue, pick something from a reputable brand at Micro Center or You-Do-It and try it out, knowing you can return it if it doesn't fit snugly. -Tom
