[busticated]

Description

Running particle usb list when one of your connected devices is "busy" or otherwise unresponsive causes the entire list operation to fail with Request timeout. This change handles device communication timeouts such that your device list is still available regardless.

How to Test

Using a device running some very bad user firmware like:

#include "Particle.h"

void setup() {
}

void loop() {
    while(1);
}

...run particle usb list with multiple devices connected and verify you still get your device list back
