Bus snooping/sniffing

Purpose and relevance to development work -- description coming soon

PCI / PCIe

Snooping Utilities:

• BTSpy [1] - Windows based snoop for BT8x8 based devices
• Dscaler's RegSpy [2] - Windows based; contains the ability to snoop the registers of PCI / PCIe interface chipsets ... also see this note

USB

Snooping Utilities:

• usbsnoop - a Windows based utility for sniffing/monitoring communications traffic for a USB device. Note: In case usbsnoop/SniffUSB doesn't work for you, here are a few time limited apps that should work under Vista:
  • USB Monitor - 14-day trial period
  • USBlyzer - fully functional evaluation version for 33 days
• SnoopyPro - Windows based snoop for USB device communications traffic
• usbsnoop/SniffUSB - Windows based snoop for USB device communications traffic
• usbmon - Linux kernel module which can snoop USB device communications traffic
  • Wireshark - logs usbmon output, via libpcap
  • USBMon - logs usbmon output

Log parsers, format etc

• parser.pl
• usbmon2usbsnoop

...

Command Playback Utilities:

• usb-robot - plays back USB Snoopy capture logs
• usbreplay - plays back usbsnoop capture logs
