Dongle order and maximum
Hi Guys,
I have two questions:
1. What is the maximum number of USB dongles that I can connect (if there is a maximum at all)?
2. Is the ordering of the device ID's of the dongles guaranteed? I.e. when I reboot the system does hci0 always point to the same device or is the ordering random?
Regards,
Herman Meerlo

Inside the kernel there is no real limitation. Except that the internal ID is a uint16. The underlaying bus (USB etc.) is more of a limit.

From the userspace tools we support 16 devices.

The order is random. You need to identify the devices with their BD_ADDR.
