USB Usage Limitations for UPort

1.A maximum of 4 UPorts can be connected to each host. Connecting more than 4 UPorts will cause system resources to become low and unstable.

2.We recommend connecting the UPort directly to the host USB port. If you need to use an external USB hub, only the first level is recommended.

3.In general, there are 2 types of USB hub:

i.High power hubs require an external power adaptor, and provide 500 mA of power to the USB port.

ii.Low power hubs get power from the host PC, and provide 100 mA of power to the USB port.

The following table shows what type of USB hub should be used with UPort 1200/1400/1600 products.
