Hi, I'm certain the subject of the USB3 channel on the latest motherboards and their problems in Windows 7 have been discussed many times already, and I'm certain all discussions are not the same. So here goes my version: At the time of this discussion I'm on my third Intel Desktop board, being under warranty my supplier changed my board three times. [what a grand Supplier!] The first and second boards were: DH67BL boards and the third board, which is current, DQ67SW - I've been having USB3 problems with all three boards I'm 100% certain it's a Windows 7 issue and not the Intel drivers that ship with these boards. My reason for saying this is as follows: testing was done on the latest board: I switched off my PC and installed Win7 Ultimate on a blank 500gig drive - then I tested my USB2 & USB3 devices on both USB2 & USB3 channels without any drivers or SP's installed - no problems, both the USB2 & USB3 devices functioned without a hitch.Then I installed [and restarted] all the latest drivers previously downloaded from the official Intel Support Download Centre Website - tested both USB2 & USB3 channels with both USB2 & USB3 devices - and Win7 prompted me after I've inserted said- devices into the USB2 port/channel, about the fact that "this device will work/perform faster if inserted into a USB3 port/channel" - the very same happened when inserted into the USB3 port/channels.Then I installed the Win7 SP1 restarted my PC, and tested the USB devices as before and Windows prompts me that "this device will perform/work better when inserted into a USB3 port, whether inserted into the USB2 or USB3 ports. I must admit that this is a very frustrating issue, especially since I've spend loads of money on this new technology. If windows 7 is not the culprit, where do I go from here. I've made doubly certain that the firmware is up to date on my external Western Digital 1TB Passport drive, my 8gig flash stick obviously don't have firmware updates. Both these devices are USB3 devices, and reported to be USB2 backward compatible. Are we going to see a SP2 for Win7 in the near future with better support for the USB3 standard? These prompts I get, are they MS or Intel related? Well. Nick.
