Hi,
I'm trying to flash firmware onto a new atusb dongle but:
Is this one of the dongles from the recent builds or is it an old one?
The new ones already come with version 0.3 of the firmware. :-)
...but I want to be able to flash my own in the future ;)
Sure enough. :) Just mentioned that because you flashed the 0.3 firmware
file which is identical with whats on it.
Happy to see someone hacking on the firmware side as well. :)

Seems you tried to flash the device when already out of the bootloader mode.
Please try the above command again when inserting the dongle. The device is
in the bootloader, waiting for firmware updates, as long as the red LED is
on after insertion.
That worked:

Good. That will get you going.
I was thinking about s.th. like bootloader mode in the first place but
this deceived me:
Device really in Runtime Mode, send DFU detach request...
Resetting USB...
dfu-util: Device has DFU interface, but has no DFU functional descriptor
so I thought dfu-util would be able to get the device back into
bootloader mode. And in fact if the device is in runtime mode already I
do see a device reset (the red led turns back on) but it the fails. Is
this a bug in dfu-util or expected? If so should it be documented like
in the attache patch?
You observation is right, it performs the reset as it should. I run into
that myself but its all the way down on my todo list to work out what is
the problem here. Is it dfu-util? Is it the firmware? Or just some
simple race?
Even when working on the firmware myself I found it working well enough
to plug and unplug the device when wanting to flash a new version. There
is also a little userspace tool which can reset the device over libusb.
Its in the git repo somewhere.
For now I can take the doc patch to make it clearer. If you have an
interest to work out what is going wrong and make the update working
smoothly from a device already after the bootloader that would be great.
Happily accepting patches to the firmware if the bug is in there. :)

Stefan Schmidt
