IDE does not see COM port

Post by warner »

I folllowed the steps in https://github.com/rogerclarkmelbourne/ ... stallation for Windows (10) but there is no Comport other than the one on the motherboard. I did do the install_drivers.bat as superuser.
In the device manager "Universal Serial Bus-controllers" there is an Unkown USB-device (request for devicedescriptor failed) (this is my best translation from the real Dutch info).
As Roger says I have to upload the blink sketch to get it working but the upload does not work. Chicken and egg?
I tried a FT232 but that fails as well saying:
maple_loader v0.1
Resetting to bootloader via DTR pulse
Searching for DFU device [1EAF:0003]...
dfu-util - (C) 2007-2008 by OpenMoko Inc.
This program is Free Software and has ABSOLUTELY NO WARRANTY


Couldn't find the DFU device: [1EAF:0003]

Any ideas?
BTW I don't have the DTR line connected to some pin (boot0 or boot1?).

Maybe retry "serial-USB" following these instructions:

Be sure to follow each step carefully.

I have used the method often, it has never failed.

To clean-up unused COMM instances, follow MS's instructions:
