Hi,

I use a Mangoh Yellow with a WP7702 chip

My problem is that when I try to mount a USB stick by UUID, the system hang

> mount UUID=563F-A62E /home/USB/

and if I try to modify /etc/fstab to mount by UUID, the Mangoh does not boot.It’s stuck on the mount phase and it reboots indefinitely.

Has anyone encountered this problem, if so have you found a solution?

Thank you,  
Jeremy

Why don’t you mount like this?

```auto
mkdir "/tmp/usbflash"
/bin/mount -t auto -o sync /dev/sda1 "/tmp/usbflash"

```

You can try the following to get the UUID  
blkid /dev/sda1

Hi,  
the result of the command : blkid /dev/sda1

> root@swi-mdm9x28-wp:~# blkid /dev/sda1  
> /dev/sda1: LABEL=“USBTest” UUID=“563F-A62E” TYPE=“vfat”

If I don’t mount like this, it’s in case there are several USB keys to mount, I have to mount each of them in their directory

but if mount cannot be used with UUID, I find a good workaround 🙂

> blkid /dev/sd\* | grep My\_UUID | sed "s/:.\*//

This returns the partition that matches my\_UUID  
After that I can just use an if condition to mount the partition in its directory

Thank You,  
Jeremy
