Potential Power Issues

We have seen 3 issues in 4 days that are likely power-supply related. The condition seen is that the wing flashes on, then goes off, and won't connect. Most likely cause is a lack of power supplied from the computer port:

Power and charging

As with earlier versions of USB, USB 3.0 provides power at 5 volts nominal. The available current for low-power (one unit load) SuperSpeed devices is 150 mA, an increase from the 100 mA defined in USB 2.0. For high-power SuperSpeed devices, the limit is six unit loads or 900 mA (4.5 W)—almost twice USB 2.0's 500 mA

Mac System Report - USB Settings and Power

Use this if the device is connected in order to check delivered power

1. Click the Apple menu and choose About This Mac.
2. At the bottom of the window, choose More Info.
3. Once System Settings open, scroll down and click System Report.
4. In the window that opens, select USB in the sidebar — at the top of the main window, you will see USB buses listed, one for each USB port on your Mac. Choose one of the USB buses and you should see all the devices connected to it beneath. If the device isn’t there, try another.

Other Issues - Serialization

We’ve identified that some mini connect products in the US have escaped QC. This means they have not been serialized. This can be identified where there is no serial number sticker containing a serial number starting with the letters CH. The cardboard packaging will also be missing a green sticker. 

Unfortunately, these products will need to be returned to ChamSys in the US in Davie, Florida. Please contact [email protected] or call on 772 410 5762 for assistance.
