SUMMARY

The discussion focuses on programmatically controlling the output voltage on a USB cable, which typically defaults to 5V. Users express a desire to adjust this voltage dynamically or toggle it on and off at specific frequencies. The conversation references a USB programming manual from Delcom Engineering, which may provide additional insights into USB device programming. Understanding the USB protocol and hardware capabilities is essential for achieving this functionality.

PREREQUISITES
  • Understanding of USB protocol and architecture
  • Familiarity with programming languages that support USB communication, such as Python or C++
  • Knowledge of USB device drivers and their configuration
  • Basic electronics knowledge regarding voltage and current management
NEXT STEPS
  • Research USB power management techniques and specifications
  • Explore libraries for USB communication, such as libusb or PyUSB
  • Study the Delcom Engineering USB programming manual for specific implementation details
  • Investigate microcontroller options that support programmable USB voltage control
USEFUL FOR

Electronics engineers, software developers working with USB devices, and hobbyists interested in programmable power management solutions.

I'm looking for a way to control the output voltage on a USB cable through programming. I don't know too much about how to program USB devices, but I know there's a default 5v output, a ground, and two data lines in every USB cable. Ideally, I would like to be able to set this voltage output to anything, or make it switch on/off with a given frequency.

Any help is appreciated!
