I'm on a bit of a break lately but I'm still puttering along slowly. The latest puzzle is the interference from the MCP 2200. I can run a board with external USB to serial converters only if I don't install the mcp2200 on board usb-serial chip. But if it's soldered on then the external serial adapters rarely work at all. I thought tying the MCP 2200's power to USB 5V would help,(V1.1RC2) as the chip would power off completely when disconnected but that didn't seem to make a difference. I'll be doing some more tests to isolate the source of trouble (ceramic oscillator, cap, chip, etc.)
Any insight would be helpful.
Merry Christmas
