SEP (Enhanced USB Redirection Driver)

SEP suite or components are used when Enhanced USB redirection driver is used in HyWorks.

SEP is recommended for shared desktop environment as it supports USB devices isolation and does not share the devices in all the running session.

Note

USB redirection through enhanced driver is controlled from SEP license server. Therefore, all the DVMs should have SEPAPP (SEP Server Module) configured with appropriate SEP license server.
License server should have appropriate policies configured for USB redirection.
Enhanced USB redirection requires extra licensing cost.

Enable / Disable SEP, SEP Modules or Specific Devices

Configure redirection of specific devices and enable/disable specific modules from SEP Client.

Client Side Configuration

SEP Client on Windows

HyWorks client on Windows uses SEP Client as independent entity. Though SEP is being controlled externally by HyWorks Client but SEP still gets installed and functions independently.

Launch SEPClient window clicking USB Client and make any device act as remote or local device.

Enable/Disable SEP

Disable SEPClient by using the toggle button displayed at the top of window.

Enable/Disable SEP Modules

Enable/disable any SEP modules by using respective toggle button. E.g. to disable USB redirection simply use the toggle button displayed against it.

Enable/Disable Device

Once the module is enabled, it can be expanded to view its settings and available devices. E.g. if USB Redirection is enabled on client side and couple of USB devices are plugged to the device, expanding Enable USB Redirection section will display settings along with option to make any specific USB device as remote or local.

To make any specific device redirected to remote session, click toggle button to change its status from local to remote.

SEP Client on Linux

SEPClient gets installed with HyWorks client on Linux desktops or Linux based HyDesk devices and always works as an integrated module of HyWorks.

View of USB devices from Login screen > Settings windows > USB Devices tab and select/ deselect USB devices.

Select the checkbox Redirect displayed against the Device name to enable the USB device for redirection in remote session.

Server Side Configuration

Enable/Disable SEP Modules

Toggle buttons provided against each module can be used to enable or disable modules.

Connect/Disconnect USB Devices

As shown in below image, toggle button displayed against each of connect USB devices can be used to connect or disconnect USB devices in remote session.

Troubleshooting

USB Hard Disks appear twice

When USB Hard disk is being redirected using SEP, it appears twice in DVMs. The issue can be solved by following the below given steps:
1. Log in to Administrator account and open command prompt and execute the following command
  
  mountvol.exe /R
  
  mountvol.exe /N
SEP4.7.0 SEP license policy server by default runs on port 7829 (if it is required to configure on some other port, follow the below steps:
1. Go directory C:\Program Files (x86)\Cinfin\CDS\runtime\conf\" file
2. Update port number
MMR (Multimedia redirection) should be kept disabled on SEP for better performance Audio and video using HyWorks.
