Thermal Image not loading #4

Closed StellaLH closed 6 years ago

StellaLH commented 7 years ago

I've followed all the instructions for building GetThermal with a Raspberry Pi and the GetThermal window opens.

However, the thermal image is missing when I do so. I've probably missed something simple, but was wondering if you have any advice? 2017-07-05-134318_1920x1080_scrot

uvc_find_device is returning an error "No such device". Is the camera plugged in and turned on, and do you see it listed when you run lsusb?

Don't know if you have already solved this but I had the same problem but it worked for me running ./GetThermal as sudo.

I'm getting the same issues still. How did you fix it? Running ./GetThermal as sudo did not work for me.

Sometimes the lepton pops out of the PureThermal2 camera socket just a hair and causes a similar issue for me. Pull out the lepton and re-insert it into the socket.

Hi all, this is an old post but I hope somebody here can give me any news on how to solve this problem. I'm working with Ubuntu Linux 18.04 and Flir Lepton 3.5 + PureThermal 2. I followed all instructions for building libuvc and GetThermal but I'm getting the same error as reported in here. I understand the camera is not being detected but I don't know how I'm supposed to solve that since the camera is just a USB cable connected to the PureThermal2. The camera seems to be working since the small led is blinking from the moment I connect the cable.

Does the result of lsusb tell you that your computer sees the USB device? You can also try unplugging the camera, run dmesg -w and then plug the camera back in to see if that gives you any hints. I don't have access to this equipment any longer so my help will probably be limited

I found the problem to be the USB cable I was using to connect the camera. I changed the cable and now I the camera is recognized. Thanks for your help... I'm wondering if there is a way of using the camera as a normal user (not as sudo)

@apolo74 What kind of cable did you change to? I'm having the same problem and have gone through several cables already.
