No sick_tim3xx device detected about sick_tim HOT 8 CLOSED

Did you connect the Sick Tim310 laser scanner to the USB port? Did you connect it to an external power supply? Is the LED lighting up in green?

from sick_tim.

Yes, I did. It is lighting up in green!

from sick_tim.

Well, I dont know how but now it is detecting the lidar and is giving this warning constantly

[ WARN] [1371814789.317046529]: LIBUSB - Read Error: LIBUSB_ERROR_TIMEOUT.
[ WARN] [1371814789.349312288]: received more fields than expected (expected: 580), ignoring scan

from sick_tim.

The communication with the scanner still doesn't seem to be working properly; the LIBUSB_ERROR_TIMEOUT means that we tried sending data, but the scanner didn't reply. I've never seen that happen before, so I'm afraid I can't help you there. Maybe check that you're using the correct voltage etc.?

Wait a minute... actually, the device seems to be sending something intermittently: First, there's a timeout, then we get a message, but it is too big. Strange. There are a few more things you can try:

1. check whether the problem goes away after a few seconds, check if rostopic echo /scan outputs something
2. change the value of USB_TIMEOUT to something bigger (in file src/sick_tim3xx.cpp)
3. comment in the two lines containing "received message was:" and send me the first couple hundred lines of output.

Yes, its actually running.
Its is giving the correct topics with rostopic list.

What about the other points I mentioned?

Closing as invalid because OP doesn't respond. For future reference: two more scanner types have been added to the package, so chances are the scanner will be supported by one of those. See the sick_tim3xx roswiki page.
