   Hello,

   I've just upgraded my Linux version to ubuntu 11.04, and it now takes much more time to upload my 75kb bin to the maple mini.
   It used to take around 2 or 3 seconds, and now it's closer to 30 seconds.

   I don't remember having changed something else...

   Does anyone saw this behaviour ? Or have an idea how to go back to the quick upload mode ?

   Thanks,

   Xavier

   Hey Xavier,

   Have you got any updates on this? There's another user reporting problems uploading with Ubuntu 11, but they can't get anything uploaded at all.

   What does $ dfu-util --version tell you?

   Hey Marti,

   No update, it works so i didn't spend a lot of time on it.

   On Ubuntu 11.04: takes 53 secondes to upload my binary.

   I still have an Ubuntu 10.10 on my laptop: it takes 5 secondes to upload my binary.

   After my last post i deleted dfu-util v0.3 from my ubuntu 11.04 and install a v0.1 I found here :
   http://dfu-util.gnumonks.org/releases/

   I had to install the libusb-dev package :
   > sudo apt-get install libusb-dev

   then in dfu-util :
   > ./configure
   > make
   > sudo make install

   And the quick upload is back :-)

   Thanks

   that is very interesting. We will ping the dfu-util guys for some theories on this - because I definitely have none.

   the word from the dfu-util guys is that dfu-util v0.1 made some non-standard choices which led to fast uploads despite the fact that the maple bootloader is misconfigured (actually, that it's missing a configuration parameter related to timeouts). there's some increased standards compliance in v0.3 which caused the slowdown. they recommended a workaround to us which will let us continue to use the existing bootloader; i'll try to get this in for 0.0.12:
