Hello,
I am currently working on a project to connect the MSP430 eZ430-RF2500-SEH to an Arduino Uno via a USB connection. I plugged a receiver from this package into a female USB port and plugged in the cables from the USB into a 5V power supply, ground, and the TX and RX pins. I cannot figure out how to get the readings from the TX and RX pins, though. Any suggestions? I should be getting in a temperature reading, but am having trouble..

If I understood you correctly, you have a device which is designed to be plugged into a USB host port e.g. on a PC.
If you want to connect it to an Arduino then you will need to provide a USB host port on the Arduino. Some Arduinos have these built in, others can have them added by using a USB host shield. Either way it requires a controller as well as the physical socket and is not something you can expect to work just by taking the data wires into a UART. The USB host controller will need to be programmed with the host part of the USB protocol that the device uses. Depending on the device this might be 'just' a matter of finding a USB host controller program (for your type of USB host port) for a serial port, or a keyboard, or a common device like that. However, if the device doesn't use one of these common USB protocols then you might end up having to write your own USB host controller program. I'd consider that quite an advanced project.
