What does it mean problem with USB? Usb on arduino is just a serial connectivity, when set to a baudrate you compiled amforth for it must work. It is like a serial dongle. With arduino be aware there is the mcu reset conected to a rs232 siganl (rts/cts or dtr..) via a 100nF capacitor (for forced reset when uploading via bootloader) so it might reset your mcu when connecting/diconnecting usb.
Do you flash both hex and eep files (you have to). Did you set fuses properly (for given chip)? What kind of programmer do you use?
