by NSH_FILEIOSIZE. An appropriate location for the

NOTE 1: When any other device other than /dev/console is used
for a user interface, (1) linefeeds (\n) will not be expanded to
carriage return / linefeeds (\r\n). You will need to set
your terminal program to account for this. And (2) input is
not automatically echoed so you will have to turn local echo on.
NOTE 2: This option forces the console of all sessions to use

---help---
Normally NSH uses the same device for stdin, stdout, and stderr. By
default, that device is /dev/console. If this option is selected,
then NSH will use a USB HID keyboard for stdin. In this case, the
keyboard is connected directly to the target (via a USB host
interface) and the data from the keyboard will drive NSH. NSH
output (stdout and stderr) will still go to /dev/console.

If NSH_USBKBD is set to 'y', then NSH_USBKBD_DEVNAME must also be

---help---
Enable builtin USB trace support in NSH. If selected, buffered USB
trace data will be presented each time a command is provided to NSH.
The USB trace data will be sent to the console unless CONFIG_DEBUG_FEATURES
set or unless you are using a USB console. In those cases, the trace
data will go to the SYSLOG device.
If not enabled, the USB trace support can be provided by external
logic such as nuttx/drivers/usbmonitor.
