Connect. USB keyboard / BCR - Dmesg finds the device. lsusb -t or -v shows the VID / PID, but USB HID does not appear in the Dev folder, not does a new device in Input events.. event 0 1 or 2 will not show data.. i.e.Cat /dev/input/event2

The same can be said for a USB printer when connected..,. /dev/lp* does not appear. ( or any other entry) .. dmesg and lsusb - both show the printer as being attached

How to enable USB ports device support?? Does this have to be done as part of the kernel setup, or can USB support be downloaded via OTA functions such a via apt-get or intstall?

Of note, USB peripherals were not recognized via either build root O/S or firefly supplied ubuntu.
