Kept getting it using my laptop USB to serial. Here's how I fixed it:
Control panel - System - Hardware - Device Manager: expand Ports:right click on USB Serial Port, click Properties. Select Port Settings tab, click Advanced. Under BM Options, lower Latency Timer value. Mine was 16, I lowered it to 12, no problems now. I up'ed it 16 again, and BS2 acted up again. Set it back to 12 and works fine. I can use my laptop with my robot now !!!

    For future reference this is covered in the Troubleshooting FAQ at the bottom of our USB Driver Download page on our website. many customers have to go as low as 3 or 4 on the Latency Timer for it to work properly.· This varies with different laptops.· Take care.

    Thank you for the info, didn't realize the FAQ list was there.
  • Sorry for the necro bump, but this still is an amazing solution.
