My x-arm is not moving.

[hassanismail92]

My USB is detected by the Ubuntu Linux Machine, When I tried to launch the comman python xarm_hardware_interface/scripts/controller.py` inside the xArm_Lewansoul_ROS folder the following error shown.

<easyhid.easyhid.Enumeration object at 0x7f04df105110>
Traceback (most recent call last):
File "xarm_hardware_interface/scripts/controller.py", line 227, in

AssertionError
Closing xArm device
Exception AttributeError: "XArm instance has no attribute 'dev'" in <bound method XArm.del of <main.XArm instance at 0x7f04e20197d0>> ignored

What to do now?

I haven’t tested this code in a while and kind of forgot what the error messages might mean. I won’t be able to look into this for a few days but meanwhile can you check that your hid raw device is created properly and your permissions are also set correctly based on the instructions in the README?

I think I there is no any need to connect Arduino? I connect X-arm board directly to the USB of my laptop. Is it OK?

This seems to be a problem due to the use of easyhid. It just flat out doesn't work, even outside this program.
