**Optional: Fix PCIe descriptor page size error**
If you encounter the following error:
```
[HailoRT] [error] CHECK failed - max_desc_page_size given 16384 is bigger than hw max desc page size 4096
```
Create a configuration file to force the correct descriptor page size:
```bash
echo 'options hailo_pci force_desc_page_size=4096' | sudo tee /etc/modprobe.d/hailo_pci.conf
```
and reboot:
```bash
sudo reboot
```
