Hi Phil, If you go to http://www.usb.org/kcompliance/view you can select product classes and see those that have passed the compliance testing. I think this might help you find a certified cable and some devices. Let me know if this doesn't help.

I picked up a Nippon Labs Usb 3.0 A Male to B Male three foot cable from Newegg. Connected the usb 3.0 drive enclosure to the W530 thinkpad usb 3.0 port, Drive was recognized but showed a Portable Device "unknown device" in the device manager, and a "device error" on the device list in the Metro UI Connected the old original usb 3.0 cable and the device shows up as a full speed usb 3.0 device in the Metro UI Just installed some windows updates. Now the old cable produces an oscillating detection/undetection of the drive in a loop. The Nippon Labs cable now seems to work. The Thinkpad bios has a setting for auto detect of Usb 3.0, but switching to manual usb 3.0 only does not help. Am running Windows 8.1 which has a brand new Microsoft driver Usb 3.0 stack to replace the intel one used in Windows 7 Using someone else's inf hack to install the intel drivers for Win 7 resulted in the OS drive getting corrupted. USB-IF (USB Implementers Forum Usb.org)has a USB compliance certification testing program: http://www.businesswire.com/news/home/20110301005115/en/USB-IF-Announces-Wav e-Certified-SuperSpeed-USB-Consumer http://www.usb.org/developers/compliance/ssusb_testing/ http://www.usb.org/developers/compliance/cable/ If a manufacturer passes the test they can label their device "SuperSpeed USB certified" However the list of certified integrators is only available to registered manufacturers, not the public The best I could do is try a google search of "superspeed usb-if 3.0 cable certified" and find that StarTech and Belkin SuperSpeed cables are certified From: [email protected] [mailto:[email protected]] On Behalf Of Phil C.

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.

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
