From the "Device Class Definition for Human Interface Devices" spec:
When a Get_Descriptor(Configuration) request is issued, it
returns the Configuration descriptor, all Interface
descriptors, all Endpoint descriptors, and the HID descriptor
for each interface. It shall not return the String descriptor,
HID Report descriptor or any of the optional HID class
descriptors. The HID descriptor shall be interleaved between
the Interface and Endpoint descriptors for HID Interfaces. That
is, the order shall be:
Configuration descriptor
Interface descriptor (specifying HID Class)
HID descriptor (associated with above Interface)
Endpoint descriptor (for HID Interrupt In Endpoint)
Optional Endpoint descriptor (for HID Interrupt Out Endpoint)
This makes that happen.

"make buildall" works, this image seems to work on the Cr50.
Also, before this CL, I see this:
0x00060f5c 0x00000000 .rodata g NOTYPE __usb_desc
0x00060f5c 0x00000009 .rodata g OBJECT usb_desc_conf
0x00060f65 0x00000009 .rodata g OBJECT usb_desc_iface0_0iface
0x00060f6e 0x00000007 .rodata g OBJECT usb_desc_iface0_1ep0
0x00060f75 0x00000007 .rodata g OBJECT usb_desc_iface0_1ep1
0x00060f7c 0x00000009 .rodata g OBJECT usb_desc_iface1_0iface
0x00060f85 0x00000007 .rodata g OBJECT usb_desc_iface1_1ep81
0x00060f8c 0x00000009 .rodata g OBJECT usb_desc_iface1_2hid
0x00060f95 0x00000000 .rodata g NOTYPE __usb_desc_end
and after, this:
0x00060f5c 0x00000000 .rodata g NOTYPE __usb_desc
0x00060f5c 0x00000009 .rodata g OBJECT usb_desc_conf
0x00060f65 0x00000009 .rodata g OBJECT usb_desc_iface0_0iface
0x00060f6e 0x00000007 .rodata g OBJECT usb_desc_iface0_2ep0
0x00060f75 0x00000007 .rodata g OBJECT usb_desc_iface0_2ep1
0x00060f7c 0x00000009 .rodata g OBJECT usb_desc_iface1_0iface
0x00060f85 0x00000009 .rodata g OBJECT usb_desc_iface1_1hid
0x00060f8e 0x00000007 .rodata g OBJECT usb_desc_iface1_2ep81
0x00060f95 0x00000000 .rodata g NOTYPE __usb_desc_end
The HID descriptor comes before the endpoint.
