![]() It was also happy to do the firmware update (along with various device resets on the way as it changed USB ID - this is why I needed the udev rule, to ensure every time the device re-appeared it would be seen by the KVM instance without manual intervention).Īfter that was complete I investigated usbmon. This gave me a Windows setup that could see the USB dongle and install the appropriate drivers. I dropped a udev rules file into /etc/udev/rules.d to ensure any device nodes created belonged to my normal user. I also told KVM to grab all the ZTE devices with -device usb-host,bus=ehci.0,vendorid=0x19d2. That involved passing -usb -device usb-ehci,id=ehci to KVM. I hadn’t yet used the USB support in this, but I thought I’d see what it was capable of.įirstly I had to explicitly enable USB2 - the device wasn’t happy with the default USB1 only stack that KVM enabled. These days I don’t have a dedicated Windows box, but I do have a Windows 7 KVM virtual machine. I was also hoping to sniff the traffic to see how to drive the voice side of things. Recently I wanted to do a firmware upgrade of a ZTE 3G modem dongle, partly to provider unlock it and partly to try and enable some voice functionality. When I first wanted to reverse engineer a USB device that only had Windows drivers the “easy” option was to take a Windows machine, install usbsnoop on it and capture the traffic as a bunch of verbose text files. However hopefully these notes will remind me enough next time.)

It makes it possible to display only selected endpoint packets in the log. Simple USB Logger allows setting endpoint filters. USB Logger aways follows the sequence of URB packets and shows pairs of submitted and completed requests. Visual tracing of URB submit/complete.To move to such packet you just need to click the button on toolbar! Simple USB Logger can quickly find packets that completed with errors. It allows to see what requests USB device was processing when BSOD occured. If BSOD occurs while you are working with USB device, you can extract log file from memory.dmp file. Simple USB Logger can display the structures of URB requests in both full and simple form (where it shows only critical data)! It is posssible to monitor any USB device, whether is it a real device plugged into hardware USB port or virtual USB device connected via any other software of any vendor! ![]()
