config USBHOST_NPREALLOC
int "Number of pre-allocated class instances"
default 4
---help---
Number of pre-allocated class instances
config USBHOST_BULK_DISABLE
bool "Disable bulk endpoint support"
default n
---help---
On some architectures, selecting this setting will reduce driver size
by disabling bulk endpoint support
config USBHOST_INT_DISABLE
bool "Disable interrupt endpoint support"
default n
---help---
On some architectures, selecting this setting will reduce driver size
by disabling interrupt endpoint support
config USBHOST_ISOC_DISABLE
bool "Disable isochronous endpoint support"
default n
---help---
On some architectures, selecting this setting will reduce driver size
by disabling isochronous endpoint support
config USBHOST_MSC
bool "Mass Storage Class Support"
default n
depends on !BULK_DISABLE
---help---
Enable support for the keyboard class driver. This also depends on
NFILE_DESCRIPTORS > 0 && SCHED_WORKQUEUE=y
config USBHOST_HIDKBD
bool "HID Keyboard Class Support"
default n
depends on !INT_DISABLE
---help---
Enable support for the keyboard class driver. This also depends on
SCHED_WORKQUEUE && !DISABLE_SIGNALS
if USBHOST_HIDKBD
config HIDKBD_POLLUSEC
int "Keyboard Poll Rate (MSEC)"
default 100000
---help---
Device poll rate in microseconds. Default: 100,000 microseconds.
config HIDKBD_DEFPRIO
int "Polling Thread Priority"
default 50
---help---
Priority of the polling thread. Default: 50.
config HIDKBD_STACKSIZE
int "Polling thread stack size"
default 1024
---help---

config HIDKBD_BUFSIZE
int "Scancode Buffer Size"
default 64
---help---
Scancode buffer size. Default: 64.
config HIDKBD_NPOLLWAITERS
int "Max Number of Waiters for Poll Event"
default 2
depends on !DISABLE_POLL
---help---
If the poll() method is enabled, this defines the maximum number
of threads that can be waiting for keyboard events. Default: 2.
config HIDKBD_RAWSCANCODES
bool "Use Raw Scan Codes"
default n
---help---
If set to y no conversions will be made on the raw keyboard scan
codes. This option is useful during testing. Default: ASCII conversion.
config HIDKBD_ENCODED
bool "Encode Special Keys"
default n
depends on !HIDKBD_RAWSCANCODES && LIB_KBDCODEC
---help---
Encode special key press events in the user buffer. In this case,
the user end must decode the encoded special key values using the
interfaces defined in include/nuttx/input/kbd_codec.h. These
special keys include such things as up/down arrows, home and end
keys, etc. If this not defined, only 7-bit print-able and control
ASCII characters will be provided to the user.

---help---
Enable verbose trace output if supported by the platform. The
intent is that if USBHOST_TRACE_VERBOSE is not defined, then only
errors, warnings, and critical messages would be logged. If
USBHOST_TRACE_VERBOSE is defined, then general informative trace
information would also be included.
