My Guess is as follows.
1 On this little motherboard you are probably using a Low Wattage power supply. As you are probably using the system a media center PC or similar…so the CASE will be small and so is the power supply unit. Please verify the Wattage of your Power supply
And maybe run a test with a higher power supply. ATX V2.2 Round 400W
2 Just to verify the facts: According Creative Web site for your USB sound card state that:
Use a self-powered USB hub
If, after connecting a USB device to the system, the system crashes, locks up, or elicits other abnormal behavior, you are likely to be putting a strain on your power supply.
One way to resolve the power issue is to use a self-powered USB hub. By using the self-powered hub it eliminates the strenuous drain on your systems' power supply, because all power going to devices connected to the hub, comes from the hub. Please be aware that some USB devices may need to be connected directly to the internal USB port, in which case; please make sure that the internal USB port is powered.
i tested problem with three power suppliers.
Second is powerman fsp300-60btv.
Third - Chieftec GPS-500AB-A.
SATA: No hdd (or present 2.5" seagate momentus 5400.4, no difference)
only one USB device is connected (creactive x-fi, model no: sb 1090).
no keyboard (or present ps/2 - no difference).
there was no ide devices.

My bios settings:
I didn't found any difference between usb ports (back of motherboard, front panel, powered usb hub in back of mother board)
1 I noticed that on BOOT you have the option USB Mass Storage Emulation Type set as ALL REMOVABLE I think that the default is AUTO. Try to change it to AUTO.
2 You mention that you have the latest BIOS version installed. Try to downgrade BIOS to one version prior to the latest.
Find below a prior BIOS link
Probably best downgrade BIOS by Recovery Mode Using .BIO
