You can get it either with usbsnoop or snoopypro under Windows. See http://www.linuxtv.org/pipermail/linux-dvb/2006-November/014682.html if you want to use usbmon with vmware player.

Firmware will be sent as soon as you plug in the device, so you should not start any programs. Sticks with remote controller might have program called Uremote.exe (or similar) running. If you do, please shut it down so that it doesn't cause traffic in logs.

m920x firmware consists of a number of 64 byte long usb control messages. After these control messages you will see another control message with request, value, index of M9206_CORE(0x22), 0x01, M9206_FW_GO(0xff69), respectively.

After usb device receives this message, it will disconnect itself from the bus and appear again with (possibly) different idVendor and idProduct. These new ids are known as warm ids. At very least you will see your device having new endpoints that will be used to transmit data.

It's important to have Usbsnoop or Snoopypro installed and logging before you plug in the device. It might take several attempts to get a dump where this firmware is visible.

After acquiring a log with firmware, you will need to process it with various tools.


Usbsnoop

First with parser.pl and then with m920x_parse (arguments -i us -m fw)

Usbmon

Recompile your kernel with CONFIG_USB_DEVICEFS, CONFIG_USB_MON and CONFIG_DEBUG_FS selected in your kernel config. Then patch linux/drivers/usb/mon/mon_text.c with http://www.rasterburn.org/~aet/m920x/usbmon_ext.diff. Finally make sure that CONFIG_USB_EHCI_HCD is set to m and not y. Now you can get vmware player and set everything ready. See http://software.newsforge.com/article.pl?sid=06/05/16/1940214 for more details on this.

You will probably need these: (look up with google if interested)

# remove usb 2.0 support. vmware might freak out your computer otherwise
rmmod ehci_hcd
mount -t debugfs none_debugs /sys/kernel/debug
modprobe usbmon
mount -t usbfs none /proc/bus/usb
# needed by vmware
chmod -R a+rw /proc/bus/usb (needed by vmware. security!!)

You need to replug your device after removing ehci_hcd module so your device sees the change. Look at /proc/bus/usb/devices to find in which bus you device is in. cat /sys/kernel/debug/usbmon/nt to a file (n is the bus number). Finally pass this file to m920x_parse (arguments -i um -m fw)

Snoopypro

m920x_sp_firmware can only read data in this format: http://www.roback.cc/projects/iRiver/howto/snoopypro/wordpad_saved.png

Useful scripts
