SpaceMouse Compact found, but "Failed to open device(Linux)

[FANMOSHENG]

I encountered an issue while trying to use my SpaceMouse Compact with the pyspacemouse library. The device is detected, but it fails to open, resulting in the following traceback:

Traceback (most recent call last):
  File "/home/ur5/.local/lib/python3.8/site-packages/pyspacemouse/pyspacemouse.py", line 183, in open
    self.device.open()
  File "/home/ur5/.local/lib/python3.8/site-packages/easyhid/easyhid.py", line 134, in open
    raise HIDException("Failed to open device")
easyhid.easyhid.HIDException: Failed to open device

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/ur5/Desktop/test/spacemouse.py", line 4, in <module>
    success = pyspacemouse.open()
  File "/home/ur5/.local/lib/python3.8/site-packages/pyspacemouse/pyspacemouse.py", line 899, in open
    new_device.open()
  File "/home/ur5/.local/lib/python3.8/site-packages/pyspacemouse/pyspacemouse.py", line 185, in open
    raise Exception("Failed to open device") from e
Exception: Failed to open device

Any idea where it come from ? Thank you.

已解决，都是中国人就不写英文了。

(1) 默认情况下，普通用户可能没有权限访问 HID 设备，可以通过设置 udev 规则解决：

cd /etc/udev/rules.d
sudo touch 99-spacemouse.rules
sudo gedit 99-spacemouse.rules

在新建的99-spacemouse.rules中添加以下内容

SUBSYSTEM=="input", GROUP="input", MODE="0660"
KERNEL=="hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c62b", MODE="0666"

idVendor 和 idProduct 的值可以通过运行以下命令找到：

lsusb

找到类似 Bus 001 Device 013: ID 256f:c652 3Dconnexion 3Dconnexion Universal Receiver 的设备，这里的 256f 是 Vendor ID，c652 是 Product ID。

(2) 重新加载 udev 规则：

sudo udevadm control --reload-rules
sudo udevadm trigger

(3) 断开并重新连接 SpaceMouse Wireless
确保当前用户属于 input 组：

sudo usermod -a -G input $USER

(4) 注销并重新登录ubuntu
