which version of Windows? JeVois has 3 devices in one:
- video camera
- serial-over-USB port (ACM CDC COM port)
- virtual USB flash drive
Here, with Windows 7, 8, 10, the camera device is always detected with no problem. Can you try a regular USB webcam and see whether that works on your computer?
On Windows 7 and some Windows 8, you need a driver for the ACM CDC COM port, see here:
