Jumpy mouse when USB3 flash drive connected.

[Jimmiegin]

Hi all. I have my new i7 machine up and running. All fully working but for the USB3 issues. So i connect my flash drive and loose control over my mouse! USB2 is fine. If i connect USB3 to VMware Windows 7 instance i get a message along the lines of "unable to connect to ideal host controller". Once i have hit the ok button i imagine it uses reverts to USB2 as i get a working mouse again for both OS X and the Windows instance. I am running Yosemite 10.10.2 on a Gigabyte Z87-UD3. Any help would be greatly appreciated. I have seen drivers on the forum but i don't want to go trying drivers that may cause more instabilities as aside from the USB3 not working properly everything is super stable.

Thanks for reading
