hi jazzzz,
Can you show your mount options.

Let's first define the sequence of particular steps (with some diagnostic) that reproduce the issue:
sudo exfatfsck /dev/sdb1
mkdir /tmp/sd
sudo mount.exfat-fuse /dev/sdb1 /tmp/sd
echo hello > /tmp/sd/test
sync /tmp/sd/test
sudo umount /tmp/sd
sudo exfatfsck /dev/sdb1
sudo mount.exfat-fuse /dev/sdb1 /tmp/sd
cat /tmp/sd/test
Please run those commands and paste here the full output.

@xunmengdeganjue /dev/sdb1 on /tmp/sd type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096)

Please remove this line in fuse/main.c to enable additional logging:
#define exfat_debug(format, ...)
Compile and install mount.exfat-fuse. Then run
sudo mount.exfat-fuse /dev/sdb1 /tmp/sd -d
This command won't detach from your terminal. It will produce a lot of logging, please post it all here after you run those commands from another terminal instance:
echo hello > /tmp/sd/test
sync /tmp/sd/test
cat /tmp/sd/test
sudo umount /tmp/sd

The log looks perfectly OK. This makes me think that the issue is somewhere else. You've said this SD card works fine under Windows. Was it the same PC, card reader, USB cable and USB port as with Ubuntu?
Could you test a different SD card on this Ubuntu PC to ensure that this behavior persists?
Could you test the problematic SD card on a different GNU/Linux PC with a different card reader and USB cable?

You can try to add a option umask=000 to your mount command,like following command line:
mount.exfat -o umask=000 /dev/sd* /tmp/sd
or
mount -t exfat -o umask=000 /dev/sd* /tmp/sd
the "*" in the command line represent the real number of you disk.
The day before yesterday,when I porting the exfat module into the OpenWRT I meet the problem too.I just add this option and the USB-storage can be wrote.

It was another PC with the same card reader.

I will try as soon as I can.
