preenfm2 and preenfm3 / Re: PreenFM2 USB issues.. (Windows 7 / 64bit)

It shows up and syncs to bpm now via USB, but when i try to send midi notes to an instrument it does not respont, tried all channels. Dont know why that is, i checked the Channel assignment etc. seems all ok, but ok baby steps, at least i got it detected and fixed the bad trace.

Made a short video, thanks for integrating the BPM Sync LED in the new Firmware after i asked you if that would be possible.
I skipped the 220 ohm resistor and used a 5mm UV LED, looks nice in person, the video does not do it any justice.

Note: I fixed the Midi Channel issue, dont know what exactly caused it, but it is working now, via USB directly, just restarted my computer

Hello
this did not help either..

But the good news is, i found the problem why the USB did not work.
It was a bad trace from Pin3 to USB Port of PreenFM. i am just about to fix it, i had no continuity between USB pin 3 and the USB Connector.

Seems that at least i have one problem solved soon

Yeah but still, i like my gear fully functional even if i dont use it
Cant seem to find the reason why the onboard USB Pins dont work, everything seems nice.
Will have a more detailed look tomorrow, and take everything apart again 

Thanks for the help so far Xavier..
Have a good night

Hey Xavier

I think we are getting nearer to the problems source
I was able to get the System to show "PreenFM mk2" once (having the USB Cable directly connected to the CERB40 and also connected the preenFM on the backside via another USB cable)

so it must be the connection on the PCB somewhere..
I already double checked if i soldered the USB Connector pins right, but its exactly like in the pic. Also minimum solder, nice solder joints, no cross connections, also reflowed.

I still dont know why i cant flash a new bootloader on it in DFU Mode, even if i would fix the USB PCB Connection problem, i would never be able to update my bootloader (or are there any other ways ?)

Will look further on the USB PCB Connection ports...

Hello

If i connect the PreenFM directly on his own USB Port it will not detect anything, no unknown device, no hidden device, nothing!
Of course i enabled the Midi in the Tools Menu i also tried all the ports, powered hubs, non powered hubs, different cables, also had the preenFM2 upside down while shuffle dancing at a full moons night, nothing worked 

i could make a screenshot but this would not help, because you wouldnt see any PreenFM device on it.
I guess i have to life with that, maybe i will buy a CERB40 on my next mouser order and try another one.

Some seem to get it working after some time, some dont.. but my main problem is, i got it detected by windows now, but still no DFU Listing. Also no detecting with connecting the PreenFM over USB. Only via direct connection to CERB40 in DFU Mode.

Same thing with the dfu-util-static

Has to be the CERB40 itself, dont know what else could be the problem.
I read on some forums that some CERB's just dont work with Win7

Hey Xavier.. well it just looks like yours, i installed, uninstalled several times etc. never got a listing with DFU-UTIL whatsoever..
there is only 0.6 available for windows. I did not find 0.7 for windows.

dfu-util 0.6

After installing the driver with Zadig i saw a Device called STM Bootloader in the device manager, but like i said before i was not able to list it with the DFU Tool.

Hey xavier

I tried that already.. 2 different powered USB Hubs, 4 different direct usb ports, no luck.
Maybe my CERB40 has some kind of defect.

None of them works.

I tried to reflash the newer bootloader in DFU Mode.. got the WinUSB Driver installed with Zadig etc. but never got a listing with DFU-UTIL.

Tried different cables and ports, also the Midi Over USB doesnt work because the PreenFM2 doesnt get recognized, not even as a Unknown Device, just nothing.

Maybe its a Win7 problem.

preenfm2 and preenfm3 / PreenFM2 USB issues.. (Windows 7 / 64bit)

« on: December 11, 2013, 03:54:37 PM »

Hey Guys
Finished my built some time ago, everything worked, but never got USB to work. So i decided to try again today.
I opened up the device, connected the CERB40 directly... nothing.. I tried to install the WinUSB Driver with the Zadig Tool for Windows Vista or later, "Driver installation failed"..
So i wanted to try the XP Version of the Tool, which installed the driver !
After that i used DFU-UTIL with no luck. Not listing anything. Tried connecting to different ports, Driver is working correctly, no listing still.
I read on other Forums that there are issues with CERB40 and Windows 7. Was not able to find a solution yet...
Drives me nuts. Too bad i dont have any other Windows XP PC around.

Someone got USB working on a Windows 7 / 64 bit Machine here ?
Thx guys
