    Default USB non-COM port terminal software?

    I have a non-computer peripheral device that connects via USB, and uses a MK22 MCU (bit like the well known STM32 family). I've snooped in on the USB port traffic between the software and the device, and found the protocol is pretty simple, sending a string of bytes that often have text in them.
    I'd like to (ahem) investigate some non-standard capabilities of the device by sending some of my own bytes to it, and see if I can pull out the bootloader of the MCU and begin to pick apart the inner workings.
    That'll require some sort of HyperTerm or similar program, but the big problem is the USB port doesn't come up as a COM port.
    Is there some sort of software that I can use to send a string of bytes to the USB port PID/VID, and see the response both in hex and ASCII / UTF?

    Some potentially useful info here in relation to Wireshark and USBPcap
    Seems Linux is a better platform for this sort of snooping
