I've done some testing with the owfs-2005-06-29.tar.gz daily configured package. Again, no luck. I've done $ /opt/owfs/bin/owserver -p19160 -u1 --foreground --error_level 9 and started the owtcl test skript: package require ow OW::init localhost:19160 set DEVICES [ OW::get ] set DEVICE [ lindex $DEVICES [ lsearch -glob $DEVICES {12.*} ] ] puts $DEVICE set STATE 0 for { set I 0 } { 1 } { incr I } \ { set STATE [ expr 1-$STATE ] puts "$I: OW::put ${DEVICE}PIO.A $STATE" if [ catch { OW::put ${DEVICE}PIO.A $STATE } message ] \ { puts $message puts $errorCode puts $errorInfo } after 500 } The log of owserver: INFO: PARSENAME path=(null) : Success ERR: Opened USB DS9490 adapter at 001/016. : Permission denied INFO: PARSENAME path= : Success INFO: PARSENAME path=/12.869736000000 : Success INFO: PARSENAME path=/12.159736000000 : Success INFO: PARSENAME path=/81.198C24000000 : Success INFO: PARSENAME path=12.869736000000/PIO.A : Success The last two lines continue with every switch of PIO.A Then I turned the mains switch, and got log lines like this: ERR: Closed USB DS9490 adapter at 001/016. : Protocol error ERR: Failed to configure/claim interface on USB DS9490 adapter at 001/016. : Protocol error ERR: Failed to reconnect USB DS9490 adapter! : Protocol error ERR: BUS_reconnect, returned error = -5 : Protocol error INFO: PARSENAME path=12.869736000000/PIO.A : Success ERR: Failed to open USB DS9490 adapter at 001/016. : Permission denied ERR: Failed to reconnect USB DS9490 adapter! : Permission denied ERR: Failed to open USB DS9490 adapter at 001/016. : Permission denied ERR: Failed to reconnect USB DS9490 adapter! : Permission denied ERR: BUS_reconnect, returned error = -5 : Permission denied INFO: PARSENAME path=12.869736000000/PIO.A : Success The last block has been printed again with every attempt to switch PIO.A. In the meantime, I got from dmesg USB error messages like this: usb 1-1: new full speed USB device using uhci_hcd and address 15 0: addr=81, size=32, dir=IN, type=3 1: addr=2, size=16, dir=OUT, type=2 2: addr=83, size=16, dir=IN, type=2 usb 1-1: USB disconnect, address 15 usb 1-1: new full speed USB device using uhci_hcd and address 16 0: addr=81, size=32, dir=IN, type=3 1: addr=2, size=16, dir=OUT, type=2 2: addr=83, size=16, dir=IN, type=2 usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd owserver rqt 64 rq 2 len 0 ret -71 usb 1-1: USB disconnect, address 16 usb 1-1: new full speed USB device using uhci_hcd and address 17 0: addr=81, size=32, dir=IN, type=3 1: addr=2, size=16, dir=OUT, type=2 2: addr=83, size=16, dir=IN, type=2 I think the problem is the usb adapter gets enumerated automatically, and gets address 17 instead of 16, so it can't be found by the reconnect function. Hope that helps. Jan -- "I'm not a programmer, but I play one at Microsoft."
