WIN 7 ISO - I only have usb3.0 ports...

So My problem is this: I have windows7 home premium iso onto a flashdrive. I go to install on my new build to get an error. I eventually find out it is because I am plugged into a usb3.0, which isn't supported by the operating system. I was told to move to a usb2.0 and retry.
the PROBLEM is that I do not have any usb2.0! I have a thermaltake chaser a31, wich has 2 usb3.0, and an asus z87 pro, which also does not have any usb2.0. What can I do to bypass this so I can get this iso to work?

  1. is there a bios option for a legacy usb mode

    So I should enable legacy, or disable?
  3. if its off turn it on, and vise versa. it cant hurt to experiment with other usb options, you can always reset to default settings
  4. Is there a USB 2.0 on the back of the case? You probably shouldn't install OS' from the front USB anyway.

    Obviously the only ports on the back of the case are behind the i/o, which I stated the z87 pro only uses usb3.0
  6. Update: After I changed my usb legacy from enabled to disabled, I lost my boot option that I was using-the flashdrive.
    There were two options for the flashdrive before I did this, one was sandisk__, the other was UEFI sandisk__, the option without the "UEFI' in its name was the one I used, now it's gone. The 'UEFI' option wont initiate windows, only boot me into linux.
  7. did you revert the setting?
  8. Some of the USB3.0 ports will be fed from the chipset, while some are fed from third-party controllers. You want the chipset ones.

    Yes, I did. I am still messing with my bios, and I managed to get back into windows installation. I still have the same error, but now I can open up (C: ) and (X: ) to browse them. But it still says no device drivers were found. When I click browse, I have GSP1RMCHPXF (C: ), and Boot (X: ). Don't really know what else to do, considering I dont even have an optical drive on this build.

    Well, instead of clicking respond to, i clicked choose best answer on accident...
    Can you please tell me what that means, and how I can use it to override this issue?
  11. Your motherboard has internal usb2 connectors. You could get a usb hub front panel add-on or an adapter to fit in a rear expansion slot. Probably less than $10. Three day shipping from Newegg or maybe even at BestBuy.

    Does internal mean I can take my case cover off and plug my flashdrive directly into my mobo? That would be perfect if it does..
  13. No, the internal connector has pins.

    This would take a few minutes to install:

    You can use the internal USB ports with an adaptor, like above.

    The USB3.0 ports come from two different sources. The chipset, which have all the drivers installed pre-boot and work nicely, or a third party chip. Intel's chipsets only have 6xUSB3.0 ports on them, so all the ones above there are from a seperate chip which needs drivers.

    Some of the ports will work, some won't. Usually the front panel ones are off the chipset, and should work.
