VS-20 Editor reports "Unable to read/write data" on launch

Last updated on 3/31/2016

Sometimes, when you connect the VS-20 Hardware to a different/new USB port on your PC, the VS-20 Effect Control Port will be lost. The following steps are used to reclaim the port and restore communication between the VS-20 Hardware and the VS-20 Effects Editor.

  1. After connecting the VS-20 Hardware to a USB port on your PC, the message "Unable to read/write data" may appear. First, be sure you have completely connected the USB cable to both the VS-20 Hardware and a USB port on your PC. If the cable was not completely connected, close and reopen the VS-20 Effects Editor. If the message still appears, it is possible the Effect Control port was lost.
