Actia Psa Xs Evolution 9780z5 Driver Guide

Use USBDeview to remove ghost devices. | | DiagBox says "No interface found" | Driver installed but software points to wrong COM port | In DiagBox configuration, manually set the COM port to match Device Manager. | | Random disconnections during SIDI/EDC17C10 programming | USB power saving enabled | Go to Power Options → USB selective suspend → Disabled. Also, in Device Manager → USB Root Hub → Properties → Power Management → Uncheck "Allow computer to turn off". | | Driver installs but shows "ACTIA PSA XS (Old)" | Wrong INF file used | Force update driver → "Let me pick from a list" → Choose the specific "9780Z5" entry, not generic ACTIA. | actia psa xs evolution 9780z5 driver
