  3. Presentation Goals • Review The Feature • Instruct On How To Configure • Provide Troubleshooting Resources

  4. Agenda • Overview of the USB Technology • Feature Components • Deployment Checklist • Configuring USB redirection • Troubleshooting USB redirection • Optimization • Case study: USB redirection of Imaging Device

  5. USB Overview Virtual Channels Virtual Channels 10110110 ICA 10110110 ICA 10110110 ICA 10110110 VDA Receiver

  6. How Do We Redirect Devices ? USB Printing Camera Audio TWAIN Standard Standard TWAIN Audio Camera Printing USB 10110110 ICA 10110110 ICA 10110110 ICA 10110110 ICA 10110110

  7. How are devices categorized? • Descriptors • Vendor ID, Product ID, Class ,Subclass ,etc • Classes • Mass Storage, Image, HID etc.

  8. Feature Components

  9. Feature Components Receiver • Citrix Remote USB Device Driver • Desktop Toolbar • Connection Center • GPO Computer or User policy • Registry VDA • Citrix Remote USB Host controller • Citrix USB Service • HDX Policy via Delivery Services Console

  10. Deployment Checklist • Citrix Receiver Polices Configured • HDX Policies Configured in the Console • Verified Device is not Redirected natively • Verified Conflicting Polices are disabled • Verified Software supports redirection method

  11. Configuring USB Redirection

  12. What are the Five Core questions ? • How should the Receiver handle existing devices? • How should the Receiver handle new devices? • Should we list USB devices in the Desktop Viewer? • What devices types should be redirected automatically ? • What devices are allowed or blocked ?

  13. Receiver Configuration: Desktop ToolBar GUI

  14. Receiver Configuration: Desktop Toolbar GUI

  15. Receiver Configuration: Citrix Connection Center

  16. Receiver Configuration: Computer Policy ADM Template

  17. USB Device Classes Allowed by Default Different classes of USB device are allowed by the default USB policy rules: • Audio (Class 01) • Physical Interface Devices(Class 05) • Still Imaging (Class 06) • Printers (Class 07) • Mass Storage (Class 08) • Content Security (Class 0d) • Video (Class 0e) • Personal Healthcare (Class 0f) • Application and Vendor Specific (Classes fe and ff)

  18. USB Device Classes Denied by Default Different classes of USB device are denied by the default USB policy rules: • Communications and CDC Control (Classes 02 and 0a) • Human Interface Devices (Class 03) • USB Hubs (Class 09) • Smart Card (Class 0b) • Wireless Controller (Class e0)

  19. Device Rules Syntax: {Allow: | Deny:} followed by any number of <tag>=<value> qualifiers. Multiple rules should be separated by semicolons. Comments start at '#' and continue until a semicolon. For example 'Allow: VID=1234 PID=5678 # Comment ; Deny: Class=03'. Allow: VID = 045E PID = 00F9 # Microsoft USB Keyboard; Deny: Class = 03 #Deny other HID’s'

  20. Receiver Configuration: User Policy ADM Template

  21. Receiver Configuration:Registry HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\GenericUSB • How to Configure Automatic Redirection of USB Devices • http://support.citrix.com/article/CTX123015 HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\ICA Client\GenericUSB\Devices\VID091E PID2353 "AutoRedirect"=dword:00000001

  22. DSC Console ConfigurationHDX Device Rules Examples of administrator-defined USB policy rules: Allow: VID=1230 PID=0007 # ANOther Industries, ANOther Flash Drive Deny: Class=08 subclass=05 # Mass Storage To create a rule that denies all USB devices, use “DENY:” with no other tags.

  23. Troubleshooting USB redirection

  24. Troubleshooting USB redirection • CdfControl • HDXMonitor • DebugView • UVCView

  25. Common Diagnostic Facility (CDF) Tracing • Recommended Modules • Portica_Service_USB • Policy_ICA_VC • PE_Library_CtxCppBase • PE_Service_CtxSvcHost • Provides a diagnostic conduit to all Citrix binaries. • Lots of new features, frequently updated • Now allows remote tracing and XenDesktop log review • Article: CTX111961

  26. Citrix HDX Monitor • Reports real-time status • Provide Network Performance statistics • Reports the active USB device rules • Delivers USB filtered Event log messages

  27. Optimization:Configuring Bandwidth Limits • Client USB device redirection bandwidth limit • Client USB device redirection bandwidth limit percent

  28. Optimization:Adjusting Priority of Virtual Channel How to Change Virtual Channel Priority in XenDesktop 5 - CTX128190

  29. Case study: Redirecting a Scanner [Imaging Device]

  30. Case study:USB redirection of Imaging Device Background: • Poof of Concept Pilot in which scanning was a key requirement for the move to XenDesktop 5.5 • Issues Reported : • Scanning Failed via Twain redirection • Scanning failed via USB Redirection

  31. Case study:USB redirection of Imaging Device Troubleshooting TWAIN: • Verified Polices on Server • Reviewed Generic USB Polices for conflicts • Reviewed endpoint configuration • Removed USB Policies • Reviewed software used to test

  32. Case study on USB redirection of Imaging Device Resolution: TWAIN • Document Process • To enable Citrix Twain Policy • Deploy correct driver to endpoint • Review if software is Twain aware

  33. Case study:USB redirection of Imaging Device Troubleshooting USB Redirection: • Verified HDX Polices in Delivery Services Console • Reviewed Generic USB Polices on endpoint • Attempt with Basic Configuration • Reviewed endpoint configuration • Removed USB Policies • Reviewed software used to test

  34. Case study on USB redirection of Imaging Device Resolution: Generic USB Redirection • Document Process • To disable Citrix Twain Policy • Deploy correct driver to VDAs

  35. Resources Covered • How to Configure Automatic Redirection of USB Devices • USB Class Codes • How to Change Virtual Channel Priority in XenDesktop 5 • HDX Monitor

  36. Resources Covered (continued) • CDF Control • DebugView • UVCView
