well

my computer is an asus notebook k40ie series (4/5 years old)
(so) i think usb port are 2.0

i'm on windows 7

i have tried differents port but not differents cables nor different computer for the moment

i precise that just before trying to configure my kobo aura h2o,
i configured a kobo glo hd with sucess
(in fact i decided to change my kobo glo hd to an aura h2o to get a higher screen 6' -> 6.8')

maybe the desktop software "think" it's always the glo hd and try to put some wrong configuration on the aura h2o.

cause i also just tried to upgrade the firmware manually with instruction "in Direct Links to Kobo Firmware" section by unzip the archive ect ...
and it worked fine,
but as soon as i launch configration on desktop sofware something happen which seem to stop the process

so i think the problem comes from the desktop sofware which do something wrong
cause even win7 tell me to format the device after that

i can precise too that i try to format as sugest by win7
but it failed
