Device Descriptor Request Failed with DigiMouse

[ExplodingLemur]

I'm using the DigiMouse library to try to implement a Cookie Clicker helper   (yes, I know you can change Javascript values, this is more interesting to me)
Anyway, I'm able to program my Digispark just fine, but when I plug it back in (after it connects/disconnects the bootloader device) I get a Device Descriptor Request Failed error from Windows.

Code: [Select]

#include "DigiMouse.h"

void setup() {
  pinMode(1, OUTPUT); //LED
}

void loop() {
  digitalWrite(1, HIGH);
  DigiMouse.setButtons(1<<0);
  delay(10);
  digitalWrite(1, LOW);
  DigiMouse.setButtons(0);
}
The vendor and device IDs are defined properly in usbconfig.h.  Any thoughts?
Thanks!
