Dead Board V3.6?

I just got my odrive 3.6, wired it up, and i get nothing on the usb. zadig does not see it. the dip switch was taped over but i took that off and set it to dfu, still nothing on the USB. So i installed openocd and used the st-link v2 - wont go into that process - i have a gold st-link with different pinouts. got this:
xPack OpenOCD, 64-bit Open On-Chip Debugger 0.10.0+dev (2019-07-17-11:28)

I installed libusb with pip but still the same

any help will be apreceated

What voltage are you supplying?

12 v 30a from a dedicated power supply. Light is on on the board

okay looked around saw that open error was because i did not have a win usb driver for the stmlink. used Zadag to install now this:

Hi,

I assume you cycled the 12V power after switching to DFU mode? Just make sure you did that, then check in Device Manager (on Windows, or lsusb on Linux). Please report your findings. If nothing shows up then it is possible it’s a defective board. Let me know.

yes i am cycling.
i get this in device manager:
Unknown usb device
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.

I unplug it that goes away

so it takes a while to show up

i tried installing driver on the unknown device with zadig - it failed

ran
(base) C:\Users\gratc>odrivetool dfu
ODrive control utility v0.4.12
Waiting for ODrive…

This can be a symptom of a bad USB cable. Can you try a short, high quality USB cable, connected without a USB hub?
