Based on the components visible on this picture ( USB connector, resistors, capacitors, and what appears to be a microcontroller), and the fact that it was stored in a medication tube,
Here is my guess
DEVICE: A custom-built USB dongle for data exfiltration or some kind of security testing
USE: It was likely used to extract data from computers or other devices via USB, possible for penetration testing or other security-related purposes.
The small size and storage in a meds tube suggest it was meant to be discreet. I thinks
I hope my guess counts... Thanks
