Nice to heard that it works with VMware. I might just add the USB IO logging
feature to VMware so people don't have to sniffer VMware again.
That would be great. The device initalizes, I can tune the stations, but
watching TV is impossible as the framerate is about one frame every 20+
seconds.
You need to have more information on what is happening in the IO.
I think you are not interested in the IO that upload the firmware.
You might want to consider the USB snoopy pro which can be down load
from sf.net. It is a tool that runs inside windows.
Tried it, it doesn't work. Here's more information.
This chip, DIB3000P, is supported by the dvb driver, however this particular
implimentation is different. Normally, the device appears on the usb bus as
a particular VID/PID, the firmware is downloaded, the device disconnects
itself from the bus and reconnects with the PID incremented by one, eg from
0xd000 at first plugin to 0xd001 after download and initialization.
The firmware is never logged by usbsnoop. I've tried it on two physical
w2k machines, with several system reinstalls on each, and two vmware
machines. I've emailed the author and he replied that there might be a
bug, but he no longer has a windows compiler and can't help.
Patrick Boettcher, the author of the DIB3000 driver, wrote his own sniffer
to get the firmware for the other devices. It did not work with this one
as it threw away the data when the device disconnected and reconnected on
the same PID.
I've speen two weeks on this, and exhausted every possibility except for
a hardware sniffer. I can't see why devio.c can't be modified to dump the
data, but I'm not familiar with the USB protocol and need help to extract
the payload from the buffer,
