"Error: Cannot write to HID device"

[Hixie]

I keep getting the following error during program execution while doing nothing but subscribing to and reading values every few seconds:

events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: Cannot write to HID device
    at Error (native)
    at sendPacket (/home/ianh/node_modules/green-bean/node_modules/gea-adapter-usb/index.js:52:17)
    at Adapter.send (/home/ianh/node_modules/green-bean/node_modules/gea-adapter-usb/index.js:150:9)

    at wrapper [as _onTimeout] (timers.js:275:11)
    at Timer.listOnTimeout (timers.js:92:15)

It's intermittent, I can't tell what's triggering it (if anything).

This is with a GE GDF570SGFWW.

FWIW this only seems to happen if the app is idle for a while. If I just keep probing the doorCount, for example, I don't see a crash.

By "idle" I apparently mean "probing less often than once every 2 seconds". I tried once every 5 seconds and saw the crash.

[Hixie]

Actually it seems even probing every 2 seconds, it eventually fails with this error.

Here's a sample app that shows the problem:

require('events').EventEmitter.prototype._maxListeners = 0;
const greenBean = require("green-bean");
greenBean.connect("dishwasher", function(dishwasher) { });

Run that for a few seconds and you get the stack above.

node.js seems to just hang after the error is shown. Timers don't keep going, but it also doesn't return to the command line. Not sure what's up with that.
