Think this depends also on the USB driver of the BCF 2000
Once I had to install everything once again, about a year ago, thing was I didn`t found the drivers anymore, so I had to look up on net.
There I found one driver that named the BCF as a single BCF device on the manager. It didn't work proper on win 8, so I found another one which made 3 devices BCF2000-1, BCF2000-2 and BCF 2000-3. It has something to do whith the MIDI Channels the device uses I think,but I also never intrested why it is like that. At that time i was just happy that I got the stuff playing again.
Also I managed to kill the drivers sometime ago so the BCF was recognized but I was not able to load my sysex because MIDIOX sent the the data somewhere but not to the BCF.
I got it away by deleting the drivers but not only the ones shown when BCF is connected but the normaly invisible drivers too. Dont know how the menu is called in English but you have to change something in the Hardware Manager Menu and you'll see every driver ever installed on the mashine (e.G. Interface drivers of devices that were connected long ago, or drivers of stuff that isn't in the PC anymore, old graphics and stuff.) By then I had the BCF drivers installed about 3 or 4 times (same ones installed automaticly as copies). Maybe this will work for your problem also. Of course delete and reinstall. Think this has to be done sometimes when using the BCF otherwise windows will become a bit disorientated one day.
If you ever expirience the problem of not getting your sysex into BCF and dont have time to find out why or reinstall, try out BOME's SEND SX. Its same programer as MIDIOX and I dont know why but mostly it works.
I know you can save the sysex on BCF whith some buttons, my problem is I have the edit and store buttons changed to normal buttons in my sysex so I cant store, if someone knows how to save in this special case tell me please as its the most critical point of my shows to get the stupid sysex on the BCF, sometimes it works with MIDI OX at first try sometimes I have to restart my laptop 5 times or do the driver clearence thing.
Thanks for the tip about 0 value will try and tell whether it worked for me, this is one of the things that frustrated me the most about BCF. If nothing helps I will sell my BCF one day as if I compare the price today and what I paid my BCF has grown its value ( I paid about 200 €, try to find it for that price now

). Still for Behringer its one of their best Products after x32 by today, if therewould not be a bcf on market it would be a sad world for cuelux as there is not a single alternative at this price for motorized faders.
