Windows 7: Win7 x64 seems to be missing core USB->serial drivers

I don't know about any high level support forums that you could try, but I would be willing to bet a nickel that your 3D printer uses an FTDI branded chip for the USB to serial interface. If it is, (and it's likely, given the popularity of the FTDI chips in this type of application), you could try the driver packages direct from FTDI (the manufacturer):

FTDI Drivers

The other alternative is that the printer uses a device from Microchip to do its USB processing. The Windows driver install pack is listed under "Documentation" on the supplied link below. It's a simple download and run installation IIRC.

MCP2200 - USB - USB Bridge


It might just work.

Thanks for the suggestion Mellon Head, I'll look into that for sure!
Nothing else I've tried has gotten me anything but frustrated.
As an added point, this is a Chinese-made printer. Does that make it more or less likely to use one of the chipsets you mentioned?

If it's Chinese, it's more likely to use the FTDI chip, or a clone of it.

Ok, thanks. I appreciate all the help folks.
I may come back to this at some point to try to bang away at it again, but for now I've given up and gone with "Plan B", which consists of scrapping the idea of connecting the printer to my PC directly at all, and installing OctoPi on a RaspberryPi 3 and running the printer control software from there. That eliminates all driver issues, and gets me back printing. More important, it preserves my sanity!
Thanks again for the help.
