Hello Ralph,
You could also omit the "-d 0483:df11" parameter from the dfu-util command line.
Ralph
Thank you for the hint, but see the man page:
-d, --device [Run-Time VENDOR]:[Run-Time PRODUCT][,[DFU Mode VENDOR]:[DFU Mode
PRODUCT]]
Specify run-time and/or DFU mode vendor and/or product IDs of the DFU
device to work with. VENDOR and PRODUCT are hexadecimal numbers (no pre-
fix needed), "*" (match any), or "-" (match nothing). By default, any
DFU capable device in either run-time or DFU mode will be considered.
If you only have one standards-compliant DFU device attached to your
computer, this parameter is optional. However, as soon as you have mul-
tiple DFU devices connected, dfu-util will detect this and abort, asking
you to specify which device to use.
If you have more than one DFU device on the USB bus it will be a problem,
so I think it is saver to add this option.
