Hi Benjamin,
I can confirm the old Banana Pi has the design problem in the USB power
circuit. It do not have the fuse to protect in case we get too much power
from the board or power the usb from the usb hub.
On Banana Pro we add an auto-recovery fuse to protect the board.

Typically, each USB port only provide 500mA current, we should not consumer
too higher than 500mA from every USB port. The total is 2 x 500mA.

I think you can contact the supplier for the refund if it in the 1st year.

Subject:  Bananapi dead by just adding USB dongles: request for a refund

Hi,

I have bought a Bananapi v1 (the one with the yellow s-video
connector) which I was very happy with till yesterday.

I added a USB hub with 4 Huawei 3G dongles on there, and that fried the
device.

I have told this to many people around, and they all agree that this
is a bad electrical design.

Questions:

1. Is there a way to have an acknowlegement from your side that it is
a design mistake?
2. What is the power limitation is mA for this particular device?
3. Have you made changes in the power supply circuits for more recent
boards?
4. Can I claim a refund?

Best regards,
