Device access permission modification
1.
Plug RK1808 AI compute stick into the USB port of PC, follow these steps to modify
the USB device access permissions
1)
Back to U disk root directory, copy “tool/update_rk1808_ai_cs_rule.sh” to “/tmp”
directory. Modify update_rk1808_ai_cs_rule.sh with executable permission.

2.
After executing the script, use the lsusb command to view the device number of the TB-
1808S0.
1)
Input the following command:
lsusb
2)
The execution result as shown below:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 009: ID 2207:0018
Notice: 'Bus 003 Device 009', '003' and '009' represent bus and device number,
