As a follow up test I've tested this with a trivial sketch that reads serial data and sends it back. I can confirm that this issue is also visible in this case:
int incomingByte = 0; // for incoming serial data
void setup() {
SerialUSB.begin(9600); // opens serial port, sets data rate to 9600 bps
}
void loop() {
// send data only when you receive data:
if (SerialUSB.available() > 0) {
// read the incoming byte:
incomingByte = SerialUSB.read();
// say what you got:
SerialUSB.print((char)incomingByte);
}
}

What does SBC represent?
I've used the Razor on multiple computers and I've never had an issue retrieving data or controlling it from a serial terminal (emulator) after the computer boots. Have you tried debugging whatever the SBC is?
from 9dof_razor_imu.
SBC is "Single Board Computer" in this context. Basically any time I was powering the machine with the board already plugged in I was having issues.

I have never had any issues with the Razor working on a Raspberry Pi from boot up. However, I have never really been trying to control it through the serial (USB) connection. I was mostly testing it out as a VR headset concept:

- Maybe it is a kernel/application specific issue communicating with the USB device? I have found screen to work consistently, don't forget to check your baud rate... I've seen some emulators display properly at double/quadruple the baud rate.
- Since you are using an SBC... have you tried just connecting it to the serial pins directly?
