Hi Edouard,

Thanks for your reply. I'm glad to here that it is possible to reset the device in 
GNU\Linux at least.

I don't think that function exists yet in *BSD, but from my very basic knowledge it 
looks like there are commands to reset ports, and change their power state within the 
*BSD driver.

I will ask the maintainers of the *BSD USB system, and see if they can help - if not 
it looks like a long weekend of reading specs :-)

Nick.

I already played with USB resetting thanks to an ioctl call in GNU/Linux. It appears 
my modem was reseting randomly so neither i commited it to the CVS nor i published a 
patch on the list.

At this time, i asked francois to find the equivalent ioctl call on BSD systems, 
and it was not implemented at all (6 or 8 months ago) so i doubt we will succeed 
in resting this modem the right way (not the GNU/Linux way). There's probably some 
voodoo command to send to the modem through the USB to reset it... but as you know we 
have not the specs of the modem, so we gave up.

But you're welcome, a good start would be to see if the BSD equivalent of the Linux 
USBDEVFS_RESET ioctl now exists. And then play with it like i did and see if you have 
more luck than i had :-)
