Does the device appear in Device Manager? If you're popping up in Device
Manager (as an unknown device, presumably), then your descriptors are
probably pretty close.

Post your descriptors here and we'll take a look.

devcon install is not what you want, that will create a root enumerated
device. use devcon update exclusively

I tried both versions: install and update. Anytime the same error.
But I've found out, that when I program my usb device to be for example a
HID Mouse, and install my driver for that device, the driver loads
successfully. But when I revert my usb-device to be the custom-device, then
the driver fails to load.
So I think it might have something to do with the configuration descriptor
of my usb device.
Do you have any idea, where I could obtain information about why windows
does or does not like my descriptor?
