After upgrading to latest CWA for Chrome the end users are not able to connect to USB devices. The message the user sees when trying to manually add the device is that the device is already in use and the transfer button is greyed out.
From version 2203, there was a change made where we are redirecting the entire device and also as part of Auto USB Redirection for session in focus the devices that were mapped will get routed to new session if that is in focus.
This is an intentional change we did to avoid USB devices from redirecting into multiple sessions the same way as other CWAs work. If the user wants to redirect the device into a new session, It needs to be disconnected from the previous session.
1. To get USB UI dialog : Open connection center widow, select the app session and then click on “Devices” button.
2. Click on “Release All” option in USB UI dialog"
This should be done from first session where you had redirected the devices.
