KIAUH 6 - Upload klipper via DFU fails

[cad435]

Linux Distribution

Armbian 24.5.1 Bookworm with Linux 6.6.32-current-meson64 on BananaPi CM4

What happened

When I try to upload a new klipper.bin so a STM32 in DFU mode KIAUH quits with the following error:

[ERROR] Unable to find a USB DFU device!
Command '"lsusb | grep "DFU" | cut -d " " -f 6 2>/dev/null"' returned non-zero exit status 127.
[WARN] No MCUs found!
[WARN] Make sure they are connected and repeat this step.

What did you expect to happen

An upload to the device

How to reproduce

Place a STM32 Board with Hardware Bootloader into DFU mode.
Try to upload klipper.bin via KIAUH

Additional information

If I manually type the command
lsusb | grep "DFU" | cut -d " " -f 6 2>/dev/null

Into the console I get
0483:df11
which would be the correct value for uploading.

the exact same procedere is working flawlessly with KIAUH v5

Can confirm this:
Bullseye RPi3 with 6 alpha: no DFU flash possible -> not found. Same with Bookworm.
With 5 works like a charm.
If you need logs, let me know.

Hi @tameike000 and @cad435, sorry for the late response, i haven't had time to look into this issue yet.
Can you both please provide the output of lsusb please? I don't have any USB devices i can flash with DFU, but i think having the raw output of the unmodified/unpiped lsusb command might already help. Thanks in advance!

FYI: i may have already a patch ready. If you are familiar with manually checking out different git branches, you could try and test if my patch works. The name of the branch is fix/KIA-545 and you can check it out with:

cd ~/kiauh
git fetch origin fix/KIA-545
git checkout fix/KIA-545

after testing make sure you check out master again, so you receive regular updates to KIAUH again

cd ~/kiauh
git checkout master
