Thanks Tim. Descriptors below. I have no endpoints; I want to fool with
control transactions first(little steps). Total length is 18.

static const configuration_descriptor_t static_config = {
sizeof(configuration_descriptor_t), // bLength
0x02, // bDescriptorType
0, // wTotalLength (calculate later)
1, // bNumInterfaces
0, // bConfigurationValue
4, // iConfiguration
0x80, // bmAttributes
250 // bMaxPower
};
static const interface_descriptor_t static_iface = {
sizeof(interface_descriptor_t), // bLength
0x4, // bDescriptorType
0, // bInterfaceNumber
0, // bAlternateSetting
0, // bNumEndpoints
0xff, // bInterfaceClass
0xff, // bInterfaceSubClass
0xff, // bInterfaceProtocol
5 // iInterface
};
