Timeouts when reading

I've got a TEMPer USB device (TEMPer1F_V1.3) running on Centos. I cloned your code and ran it, but am having odd timeout behaviour. The first time it runs, it works fine (if I just run it once or in a loop, everything is as expected), but the process exits and I run it again I just get timeouts when reading from the USB device:
USB interrupt read: Connection timed out

It seems to be sending the control message fine, but timesout when it tries to read from the USB as if there is no data to read. Any ideas why this could happen? I've not done any USB development but read through the code and it seemed to be OK. All return values from closing the interfaces and USB device from the previous run were 0 (success) so it seemed to close down OK, but the next time it runs I get the timeout. Any help would be appreciated!

Blog post.

Hi peter,

just updated the blog post using your git patch.

apt-get install libusb-dev
git clone https://github.com/petervojtek/usb-thermometer.git
cd usb-thermometer/
cp 99-tempsensor.rules /etc/udev/rules.d/
make
cp pcsensor /usr/local/bin/

Problem with collectd integration.

Im having a hell of a time getting collectd to get data from this thermometer. Tried a variety of different things to no avail. It's working from the command line. Could anyone assist by sharing more details of how they achieved working collectd integration? Even just configs might be better than randomly trying stuff. ty
