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? ...

I'm sorry to say that this problem has temporarily defeated me.

After I posted the messages above I decided to have a shot at getting it working with Microchip's C18 compiler. Initially I tried th ...

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.

Ok,

I've now changed the fuses line to

#fuses NOPROTECT, BROWNOUT, BORV20, NOWDT, NOLVP, VREGEN, PUT, XTPLL, PLL1, CPUDIV4

and I've increased the capacitance on Vusb to 320nF
