User Questions:

1. “USB Accessories disabled” error when connecting the controller to ma…

I never had any trouble with DJI Assistant 2 with my old MacBook.

However, with my new MacBook, the Mavic connects fine, but the controller doesn’t. Sometimes I buy a mistake message saying “USB accessories disabled” and recommend disconnecting the device, which is drawing an excessive amount of power.

This is a 2017 MacBook Pro with only USB-C ports. I’m connecting it to the controller with an adapter and, therefore, the same short cable I’ve always used before.

Is this a drag anyone else has experienced?

2. USB Accessories Disabled

I have a MacBook Air Retina 2019. I used to be using the hub, and it had been all working fine until now. It doesn’t recognize any of my three hard disks, but it does recognize a little Pendrive. I now (before I didn’t get any message at all) get a message that says: USB Accessories Disabled” Unplug the accessory using an excessive amount of power to re-enable USB devices. The hard disc has the blinking light on, but it doesn’t appear on my Mac, and I cannot access it. Is there an answer for this?

3. USB Accessories Disabled. Can’t Connect Arduino UNO R3 to Mac. Please Help.

Just got my first Arduino R3 UNO Starter Kit and installed the IDE 1.8.5 on my MacBook Pro. I’m excited and prepared to start out learning.

However, once I plug the Arduino into my USB ports on my Mac, the Arduino doesn’t power up, and that I get the message “USB Accessories Disabled, Unplug the accessory using an excessive amount of power to re-enable USB devices.”

I have tried plugging it into my USB ports and obtaining an equivalent message and no power to the Arduino. No other devices are plugged into my USB ports. I even have also tried rebooting and obtain an equivalent message. After I unplug the Arduino, I can plug other USB devices into the ports and work fine.

I also plugged the Arduino into the barrel plug using the 9volt wall power adapter, and it DOES power up. However, if I plan to plug the USB at an equivalent time, I STILL get the USB using an excessive power error.

Here are my computer stats:

MacBook Pro Retina Mid 2012 2.7 GHz Intel Core i7 Memory 16 GB 1600 MHz DDR3 Mac OS 10.13.1 Sierra Nevada 

I read somewhere that my USB ports put out 500ma per port. Isn’t that enough for the Arduino?

Has anyone else had this problem and found out a solution?
