Start by:
- flashing all your devices to the newest firmware.
- Upgrade the Aquasuite to newest version also.
- Update Windows, as there might have been released new drivers for your MoBo, and check your Motherbord manufactures homepage, for the same.
- flash your motherboard BIOS to newest revision.
Then you can start connecting all your devices again.
My experiance says, to use ony internal USB-headers, whilst other owners have experianced the opposite, to only use external headers.
Check if your USB-headers is all controlled by the same chip (i.e. southbridge), or if they ae controlled by different chips, and cross check, witch ports have problems, and witch have good connection.
Sometimes electronics got some very wierd ideas.
