I get a data overrun error. What is it? How do I figure out
what size gBuffer should be? The device puts out 8bits at a
time, one byte every 10msec.

I read how to understand the error code ox38   ox00 ox2e8
http://developer.apple.com/qa/qa2001/qa1075.html

looking up in IOreturn.h, 0x028 is data overrun
#define kIOReturnOverrun         iokit_common_err(0x2e8) //

numBytesRead = sizeof(gBuffer) - 1;
err = (*intf)->ReadPipe(intf, inPipeRef, gBuffer, &numBytesRead);
    if (err)
