USB Device not recognized at Computer startup

Device is recognized if plugged in after computer has booted

Device not recognized if plugged in before computer powered on, even after unplugging and plugging back in.

Host OS: Linux 16.04.01

Device: PIC24FJ128GB606

MPLab X v5.10

XC16 v1.35

Microchip Code Configurator 3.66

- PIC24 / dsPIC33 / PIC32 MM MCUs (V1.85)

- Foundation services Library (v0.1.30)

- USB Framework Lite (v1.26.1)

Hooked up as per manual page 267, figure 20-3

attached are 2 Wireshark captures. 1 of the device working, 1 of it not working.

You can see the 2 captures are pretty much the same up till Frame 49. But I can't see what the problem is or how to fix it.

Any help is greatly appreciated.
