I'm writing unit tests and I'm learning this framework and I'm relatively new to this, so bear with me... I'm working with a 'Permission denied' behavior when trying to access a USB drive mounted with FUSE on my Raspberry Pi running Raspberry Pi OS (based on Debian Bullseye). I have the drive formatted to FAT32 and used the following command to mount it: ```bash sudo mount -o uid=1000,gid=1000 /dev/sda1 /mnt/usb ``` The drive mounts successfully, but when I attempt to access it, I get: ```bash ls: want to open directory '/mnt/usb': Permission denied ``` I checked the ownership of the mount point and the USB drive with `ls -l /mnt`, and it shows: ```bash drwxr-xr-x 2 pi pi 4096 Oct 23 10:00 usb ``` I've also tried using `chmod` to change the permissions: ```bash sudo chmod 777 /mnt/usb ``` However, I still receive the same permission denied behavior. Additionally, I confirmed that the Raspberry Pi user `pi` is in the `fuse` group: ```bash groups pi ``` I can access the drive directly if I mount it as root without FUSE, but I need to use FUSE for specific reasons related to my application. I've searched through forums and documentation but haven't found a solution that works. Any suggestions on how to resolve this scenario would be greatly appreciated! I appreciate any insights! Is there a simpler solution I'm overlooking?
