"No DFU capable USB device available"


Hello all,

I decided to try setting up my Choosatron manually, but get this error in the topic when trying to execute the first command:

dfu-util -d 1d50:607f -a 0 -s 0x08005000:leave -D choosatron-core-v100.bin

Does anyone know what would be causing it? I have installed the drives, plugged in my device and put it into DFU mode.


Hi @sg_mac,

It sounds like either a driver issue or maybe needing to run ‘sudo’ (if you’re on a Mac, or Linux computer). You can check and get a list of dfu’able devices by typing:

dfu-util -l

#OR if permissions are needed
sudo dfu-util -l

# if you see a device showing up as  "1d50:607f" 
sudo dfu-util -d 1d50:607f -a 0 -s 0x08005000:leave -D choosatron-core-v100.bin

Can you give that a try and let me know if that helps?

If you’re on Windows, try opening the Command Prompt as an Administrator. :slight_smile:



Make sure it’s in DFU mode before you plug it in.

On a side note: I’ve been watching the source code changes on GitHub. There has been a lot of work on Write happening lately. Hopefully it won’t be too much longer before there is an easier way to get the Choosatron up and running.
