# Troubleshooting

### Fix connection issues on Linux

You may encounter connection issues when trying to connect to your workspace with your Personal Security Device device on a Linux environment. The following steps will help you solve this issue.

#### Step 1. Add udev rules

Create a set of udev rules to allow device access. Refer to the [Chrome USB API documentation](https://developer.chrome.com/apps/app_usb#caveats) for details. Use the following command and retry to access the application.

`wget -q -O - https://raw.githubusercontent.com/LedgerHQ/udev-rules/master/`

`add_udev_rules.sh | sude bash`

#### Step 2. Add user to plugdev group

Modify the above **/etc/udev/rules.d/20-hw1.rules** rule to match your group or add the **OWNER="username"** parameter to each line, where **username** is your Linux user name. This adds your user to the **plugdev** group. Retry once you've done this.
