我最近不得不购买一个 ti nspire，但是在通过我的电脑与计算器通信时遇到了问题，而 tilp 检测到我的 ti-83！，我正在运行 Ubuntu 22.04.1，并且我通过 bach 脚本安装了 Tilp2，但在启动时出现此错误：
Msg: failed to open the USB device.
Cause: Check that the USB cable is plugged in and that the calculator is turned ON! Also, check libusb and usbfs for valid permissions.
我在控制台中显示了这个，但我无法解决问题。
