If so, are they being powered off the USB bus? If so, it is probably a power problem. If there is an option to use an external power adapter, try that and see if it helps. If it is a 2-1/2" drive that will only get its power from the USB bus, then it probably has an extra USB connector that is power only. If it is long enough, try plugging that into the motherboard USB, and the data connector into the USB 2.0 connector. You can also try using a powered USB hub instead. If you are trying to use both drives at once, you are more likely to run into power problems. Are you using any other USB devices at the same time? One other thing - check the specs on your USB card, and on the devices that you are plugging in to make sure you have enough power. There is usually a port limit and a total limit. If you have devices that under report their power needs, or have any power-only devices plugged in, you may be at or over the total limit.
