It sounds like you have the problem with AAG products and USB-adapters like many other people have stumbled into. http://www.aagelectronica.com/aag/en-us/pg_10.html#Q29
You could try to start "owserver -u --altUSB" and then tweek the usb-timings and see if it solves the problem. Edit the file /opt/etc/owfs/owserver and add OPTIONS="-u -p 3002 --altUSB" Restart owserver # kill-owfs # run-owfs # echo 3 > /tmp/1wire/bus.0/system/adapter/pulldownslewrate.0 (Valid: 0-7) # echo 10 > /tmp/1wire/bus.0/system/adapter/writeonelowtime.0 (Valid: 8-15) # echo 8 > /tmp/1wire/bus.0/system/adapter/datasampleoffset.0 (Valid: 3-10) (Those are the default values...) First try if --altUSB flag helped you... if not, try changing the values to some different... Especially try change the slewrate to get rid of the signal reflections and read errors. The meaning of value 0 to 7 is described below. * PARMSET_Slew15Vus 0x0 * PARMSET_Slew2p20Vus 0x1 * PARMSET_Slew1p65Vus 0x2 * PARMSET_Slew1p37Vus 0x3 (default) * PARMSET_Slew1p10Vus 0x4 * PARMSET_Slew0p83Vus 0x5 * PARMSET_Slew0p70Vus 0x6 * PARMSET_Slew0p55Vus 0x7 What kind of errors are detected? # grep -v " 0" /tmp/1wire/bus.0/statistics/errors/* /Christian > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:owfs- > [EMAIL PROTECTED] On Behalf Of Giuliano > Sent: den 3 juli 2007 12:40 > To: [email protected] > Subject: [Owfs-developers] NSLU2 and DS2408 > > Hi, > i just installed an NSLU2 with unslug 6.8. > My network is very simple, i need to control a DS2408 , the connection > to the > NSLU2 is realized via an DS9490R.
