I can see that it appears a number of [USB Control] type packets are being exchanged, and witnessed a Bulk transfer. If i receive this packets the output is something like below which i do not understand. The service is called NPF (NetGroup Packet Filter). For example, when Windows requests STRING DESCRIPTOR it first asks for only 2 bytes. Back in 2013 I just ran MixControl on a Windows System inside VirtualBox on a Linux host, and used wireshark to monitor USB commands. 1 host USBMS 40 SCSI: Response LUN: 0x00 (Test Unit Ready) (Check Condition) 711 76.

Individual RTP packet data in logs. The USB URB denial of service vulnerability lies in the USB packet dissector, where insufficient checking of packet parameters is performed; the vulnerability is present only when Wireshark is configured to sniff packets from USB ports or opens a crafted USB traffic pcap file. Turns out it's being captured but either the capture is wonky or Wireshark is incorrectly displaying this data. An USB token packet contains, among other things, an address field. tl;dr - I've been looking at the USB traffic to a simple little USB device (a fan with a programmable display), and couldn't figure out how the actual data was being sent. urb_status != -115).
