This will get you started for sure: http://wiki.wireshark.org/CaptureSetup/USB If you run an recent Linux kernel then you are set with everything from the beginning as almost all Linux distro-s come with usbmon built/included as a module. The path is DEVICE <-> "raw" USB driver + usbmon <-> vmware <-> windows driver. As for writing a driver howto - just a google search away. It may seem like a lot at first look but its not rocket science. You may also want to look at libusb.org if you want just to test quick "talking" with a device from userspace. I use libusb to test the protocol before putting in a driver/kernel. |

There are few tools for Windows, look here http://wiki.wireshark.org/Tools#USB_capture . I think it is called usbsnoopy . I never tried these and have no idea how well they work; but they may be enough; was never tempted to try the Windows tools as Linux makes it so much easier. BTW, when you sniff USB most of the clients send status packets very often (order of 10-20ms - an Arduino/FTDI dings the host approx each 16ms for example). Small packets but they a really "noisy" and annoying one; typical can't see the forest because of the trees. With Wireshark you can look for these, they are usually very short few bytes only, and filter them out then capture only what is interesting. That will give you a much more decent captured data stream. |

DBGVIEW.EXE report couldnt access device driver. nevermind. also tried rawcap, perharps only for network type usb device (not working with my dds3x25) |

However, at least we have mecha here to potentially find a fix if that happens. I've run in on Win7 32 bit, XP, & Vista 32 without issues. --- End quote --- Due to a hard-drive crash, I'm now running it on 64-bit Win 7. The drivers are available on the Hantek website. I installed Goltek, plugged in the 3x25, and installed the drivers via Device Manager. No problems found to date. |
