Issue Description
I'm running the demo /wrappers/android/examples/java_example.
I have the camera connected with an USB-C to USB-C OTG cable.
I get about 5-20 frames and then get spammed by the message I/librs: Dropped frame. alloc_frame(...) returned nullptr until eventually waitForFrames() throws an "UNKNOWN_ERROR".
I tried to supply Pipeline with a Config with only the depth data enabled but the result was the same.
Config config = new Config();
config.enableStream(StreamType.DEPTH, 640, 480);
Pipeline pipe = new Pipeline();
pipe.start(config);
Here is the tail of my log:
