Hi Cris, Thanks for your post and welcome to the forum! Is the MMB0 powering up properly? It is not always clear, but the USB connection is only meant for communication, not power. You can power the board using a barrel jack connector as shown in 9.4 ADS1299EEG-FE Power-Supply Recommendations of the UG. Alternatively, you can provide voltage to JP2 and JP20 using a DC supply. Refer to Table 2. Power Supply Test Points in the UG for testing: www.ti.com/.../slau443b.pdf Re-installing the software and drivers with the board disconnected from the PC, administrator rights, and making sure that there is no anti-virus/firewall blocking the installation may be necessary.
