Never saw this box, it seems to be a new one.

It is clearly not the HanfTek stick, but it claims to have its USB IDs. 
Interesting world of USB ID allocation.

HanfTek was very helpful during the last time. I will contact them to 
check if they know something about this box.

The new USB IDs are hardwired in the Firmware.

This can't be an accident. The Box clearly has the MT352 as demod.

OK. Most likely the box just uses another tuner than the Hanftek one.

Does the original software find any channels in Windows? Can you create a 
usblog using http://benoit.papillault.free.fr/usbsnoop/ and try to scan 
for channels while recording the traffic.

Please compress the usbsnoop.log and send it to me privately or put it 
somewhere fr download.

Let's hope we can use the firmware from HanfTek... There is probably no 
way to distinguish the devices from the cold-state of the FX2 (when having 
the same USB IDs), or is there a way?

To figure out the tuner maybe, but first do the usblogging, maybe it is 
sufficient.

Good luck,
Patrick.
