Hi, I have installed Ubuntu 20.04 on a machine and plugged in the dongle but RoboDK is not detecting the dongle. When I run lsusb on the dongle's device ID

Code:

lsusb -s 21 -v

it says

Code:

Any thoughts on how to resolve this? Other USB devices connected to this machine are working, and I know the dongle works in my Windows machine.

You should start RoboDK with root privileges so RoboDK has access to the USB device.

Example:

Code:

sudo ./RoboDK-Start.sh

Gotcha! Thanks.

I also just came across the usb-dongle-setup.sh in the RoboDK folder which provides several options to address this:

Code:

如果你有一个USB软件狗许可证you may need to follow one of the following procedures to make the USB dongle work with RoboDK:

1. Make the device "hiddev0"(the dongle device) readable and writable
sudo chmod +666 /dev/usb/hiddev0

2. The first option, run the demo with root permission:
sudo ./RoboDK-Start.sh

3. Add one line code to this configuration file:
sudo nano /etc/udev/rules.d/70-persistent-usb.rules
KERNEL=="hiddev[0-9]*",MODE="0666"

4. Alternatively, modify the following file:
/etc/udev/rules.d/80-persistent-usb.rules
SYSFS{idProduct}=="8101",SYSFS{idVendor}=="1bc0",MODE="666",OWNER=“username",GROUP="groupname"
