I am using Windows 7 and I am trying to update my OWL. I connects to the OwlNest and I can get and save the settings from and to it. However when I try and update it to the latest firmware at about 16% I get a message saying:
“Could not find a connected DFU device”
I do see the device in the Device Manager as:
“STM Device in DFU Mode”
Device Type: Universal Serial Bus controllers
Device Status: This Device is working properly
Driver Provider: STMicroelectronics
Driver Date: 7/5/2012
Digital Signer: Microsoft Windows Hardware Compatibility Publisher
Hi, can you tell me what devices you see in owlnest / application settings tab ?
I will get access to my windows 7 computer on wednesday and will look into that.
Application Settings: (selected option in square brackets)
Audio Device Type: [Windows Audio] / Direct Sound
Output: OUT (3-DUO CAPTURE EX) / Digital Audio (S/PDIF) (High Definition Audio Device) / [<< none >>]
Active MIDI Inputs: [OWL FS] / 3-DUO-CAPTURE EX
MIDI Output: [OWL FS]
After I try and run the update the pedal goes in DFU Mode (I hear the USB lose and reconnect it). When I open and close OWL Nest the OWL FS Option disappears. If I reset the OWL Pedal OWLNest finds it again.
Just tried it on my wife’s laptop running Windows 8 and I get the same behavior and message.
It might be a windows driver issue. the team is looking into it.
I have the same problem with win8.1
I also am having these same symptoms when trying to update firmware
same usb dropout noises and gets to 16% and shows the Could not find a connected DFU device message
on windows vista (i know i know)
OK, reproduced the problem on Windows 7.
We found a solution today (update the driver for the Owl in DFU mode) I’ll edit the wiki and post a link in this thread asap (hopefully today).
Here is the procedure we suggest you to follow:
Let us know if this works for you, with your Windows OS version. Thanks!
Windows Vista test Update!
the procedure worked and I have now sucessfully installed latest firmware via OwlNest.
Slight difference in how the device appears in Zadig:
Device listed as “STM Device in DFU Mode”
and the driver on the left listed as
STTub30 (v188.8.131.52) until its been updated.
Others parts are the same though
USB ID 0483 DF11
Thanks for the quick response and fix.
I was able to update as well. Played around a little bit with some of the patches, tried the synthesizer patch. It worked for a few minutes but then it stopped recognizing the notes I was playing, the delay patch I had loaded sounded distorted as well. I tried resetting but all the patches sounded distorted. I will try again tonight. I might have to change the output I put it on my Pedal Power (100 ma vs 250 ma), which leads me to my next question. What is the minimum amount of mA needed to run the Owl reliably?
I’m duplicating this error on linux (Fedora 20) with the message “could not find a connected DFU device” at 16 %. What would the linux workaround be?
Hi, I’m very new to all of this stuff. I got a second-hand OWL from eBay recently, managed to plug it in, but then I attempted to update the firmware and it appears to have done a similar thing to the above. I’ve followed the instructions for the Zadig tool, but the device appears as “OWL FS (interface 0)” and not STM32 BOOTLOADER (which doesn’t appear in the list) – is that a problem? I presumed it wasn’t and updated the USB driver, which went ok. Then attempted to update the firmware but hits 16% and states the “Could not find a connected DFU device” message. Not really sure how to proceed. I think I’ve launched non-DFU mode (the LED flashes red once as per the instructions at least). Power cycling where the LED flashes red three times doesn’t seem to happen.
I’ve opened the box, and it’s a rev004 unit, but hoping I don’t need to use the wires!!!
