Title: PIC32 USB DRIVER DOES NOT WORK WITH MASS STORAGE CLASS
Description: The PIC32 USB driver either crashes or hangs when used with
the mass storage class when trying to write files to the target
storage device. This usually works with debug on, but does not
work with debug OFF (implying some race condition?)
Here are some details of what I see in debugging:
1. The USB MSC device completes processing of a read request
and returns the read request to the driver.
2. Before the MSC device can even begin the wait for the next
driver, many packets come in at interrupt level. The MSC
device goes to sleep (on pthread_cond_wait) with all of the
read buffers ready (16 in my test case).
3. The pthread_cond_wait() does not wake up. This implies
a problem with pthread_con_wait(?). But in other cases,
the MSC device does wake up, but then immediately crashes
because its stack is bad.
4. If I force the pthread_cond_wait to wake up (by using
pthread_cond_timedwait instead), then the thread wakes
up and crashes with a bad stack.
So far, I have no clue why this is failing.

USB Configurations. USB Configurations.
------------------ ------------------
Several USB device configurations can be enabled and included USB device support is enabled by default in this configuration.
as NSH built-in built in functions. USB is *not* enabled by default. The following settings are defined by default (and can be set
to 'n' to disabled USB device support).
To use USB device, connect the starter kit to the host using a cable
with a Type-B micro-plug to the starter kit’s micro-A/B port J5, located
on the bottom side of the starter kit. The other end of the cable
must have a Type-A plug. Connect it to a USB host. Jumper JP2 should be
removed.
All USB device configurations require the following basic setup in
your NuttX configuration file to enable USB device support:
CONFIG_USBDEV=y : Enable basic USB device support CONFIG_USBDEV=y : Enable basic USB device support
CONFIG_PIC32MX_USBDEV=y : Enable PIC32 USB device support CONFIG_PIC32MX_USBDEV=y : Enable PIC32 USB device support
CONFIG_USBMSC=y : USB supports a mass storage device.
In this configuration, NSH will support the following commands:
msconn : Connect the mass storage device, exportint the SD
card as the USB mass storage logical unit.
msdis : Disconnect the USB mass storage device
NOTE: The SD card should *not* be mounted under NSH *and* exported
by the mass storage device!!! That can result in corruption of the
SD card format. This is the sequence of commands that you should
used to work the the SD card safely:
mount -t vfat /dev/mmcsd0 /mnt/sdcard : Mount the SD card initially
...
umount /mnt/sdcard : Unmount the SD card before connecting
msconn : Connect the USB MSC
...
msdis : Disconnect the USB MSC
mount -t vfat /dev/mmcsd0 /mnt/sdcard : Re-mount the SD card
...
Other USB other device configurations can be enabled and
included as NSH built-in built in functions.
