Hi Ttelmah,
Thanks for the ideas. I'm going to do as you suggest and see if I can replicate the fault with a simple host running on the computer in place of mach3. By VBS did you mean visual basic? ... |

Okay, I've just realised that (of course) I hadn't correctly configured trisc. Now that I've done this I've stopped getting the erroneous int_rda interrupts. |

The other VSS pin is now connected, and I've experimented with a 470uF capacitor (as I've seen suggested elsewhere on the forum). And I've commented out the USB sense pin line.
Unfortunately still ... |
