The 'd.pcap_image_t pcapture' in usb_common.h called its constructor and set 'fd' to -1. However, in the usb_device_c() constructor, we then cleared all of 'd', resetting pcapture.fd back to zero. Then on Bochs exit, the pcap_image_t destructor tried to close the file since 'fd' was zero instead of -1. To fix this, I removed the pcap_image_t constructor and now call pcap_image_init() within the usb_device_c constructor.
