Visualize data from a Microlife Blood Pressure Monitor Premium using the WebUSB API.

Bypass permission issues

When testing this project with a Microlife Blood Pressure Monitor the following two commands helped provide access to the WebUSB API to the device in an Ubuntu 16.04 LTS environment.

  1. sudo chmod a+w /dev/bus/usb/00x/xxx
  2. sudo rmmod cypress_m8

Note for future self:

Removal of the cypress_m8 kernel module is necessary because by default it will attempt to claim the device interfaces and not allow USB API to access it. rmmod will remove the kernel module which allowed the Web USB API to claim the device interfaces!

This project does not include further instruction at this time.
