My R2 Pro was delivered with a damaged Control Unit housing. The USB connector and speaker were not working. Upon further investigation, I discovered that the USB connector was not connected to the board. I noticed the way the connector was mounted to the board, and considering the product’s weight makes it mobile and the fact that it’s not a handheld device, I believe the connection is weak to the board for this type of product.
This could be another reason for the glitches some users are experiencing. While there are other potential reasons, such as software issues, cable problems, or computer malfunctions, this could be a contributing factor. The USB connector is mounted to the board with 4 small pegs, the data connections is on both sides of the connector, so as the usb connector is used, the plugging and unplugging would weaken the data connection and explain some glitches.
My recommendation is to plug the USB cable into the unit and leave it in. However, be cautious of the loose cable and consider taping it to the unit while moving and cleaning, or be very gentle when plugging and unplugging the USB cable.
OR what would be great Bluetooth connectivity!!!
