By on April 10, 2013 in Even if you only have a moderately sized VDI deployment chances are high you will face the problem of getting USB smart card readers to work on the virtual desktops. Given that this is such a basic requirement it is astonishingly hard to implement correctly. To save you the pain of having to start from scratch here is my description of how to do it. Basics Smart card readers are USB devices, so the only thing you have to do is plug them into the thin or fat client sitting on your desk and Citrix XenDesktop auto-magically makes them appear in your virtual desktop, right? We are going to get to that magic, but we have got a bit of configuring to do first. To auto-map smart card readers like the Reiner SCT or Omnikey devices into virtual desktops we need: • USB redirection must be allowed • A redirection rule for the device type smart card via Citrix policies • A redirection rule for the device type smart card on the end user device • The USB redirection module must be enabled on the end user device (applies to some Linux thin clients) • Smart card hooks may have to be removed on the virtual desktop • The Windows Smart Card service needs to be started The following chapters elaborate on these points.

Allow USB Device Redirection Configure a Citrix user policy to allow USB device redirection by setting ICA ->USB Devices ->Client USB device redirection to allowed. Smart Card Redirection Rule in Citrix Policies Add a redirection rule for smart cards to the Citrix policy setting ICA ->USB Devices ->Client USB device redirection rules.

Allow: Class=0b # smart cards Allow: Class=0b # smart cards Make sure there is no deny rule overriding it. Smart Card Redirection Rule on the End User Device Funnily, some people seem to think that smart card readers are typically used on the end user’s device, not the virtual desktop.

MTP USB Device - Unable to see the disk in. Device driver software' It then says 'MTP USB Device' and states that it's. Was the Citrix USB Monitor Driver. INSTALLING CITRIX RECEIVER ON WINDOWS XP OR. Filter Installer Samsung S4 more. Select 'BigHand Digital Dictation Phillips Device Drivers' and. Connect to the same USB.

While this just might be true for fat clients it is downright ridiculous for thin clients. When I connect a smart card reader to a thin client I most definitely want to use it in the remote session, not on the device itself. However, the thinking that the endpoint comes first has led to the situation that the ICA client also has redirection rules.

In contrast to the rules in the Citrix policy the endpoint’s rules are even preconfigured, and in such a way that redirection of smart card readers is disabled. Obviously, we need to get rid of this. Thin Clients with Linux ICA Client (Citrix Receiver) USB redirection rules are stored in the file usb.conf which is located in the directory /setup/ica on Fujitsu eLux thin clients. The default content of usb. Rf Circuit Design Reinhold Ludwig Ebook3000 there. conf includes the line. DENY: class=0b # Smartcard DENY: class=0b # Smartcard Either delete that line or comment it out by putting a hash (#) in front of DENY. Windows ICA Client (Citrix Receiver) On a Windows machine USB redirection rules are stored in the registry value HKLM Software Citrix ICA Client GenericUSB DeviceRules. The format of that multiline string is identical to the file usb.conf on Linux.

As described above locate the entry that denies smart card redirection and either delete it or comment it out. Enable USB Redirection Module (Linux Thin Clients) Some Linux thin clients have a modular ICA client. Thus it is possible that the component for accessing XenApp and XenDesktop is installed, but the HDX Plug-n-Play module is missing. In case of eLux make sure to install HDX Plug-n-Play USB 2.0. Optionally Remove Smart Card Hooks If you have followed the steps above you have done everything that is required to get smart card readers working in your virtual desktops – theoretically. In practice it can happen that the readers do not work reliably.

In that case Citrix’s smart card hooks may interfere with the redirection. This can be resolved by deleting the hooks. The Office Uk Torrent Completed here. To do that delete the following registry keys on the virtual desktop: • HKEY_LOCAL_MACHINE SOFTWARE Citrix CtxHook AppInit_Dlls Smart Card Hook [32-bit and 64-bit systems] • HKEY_LOCAL_MACHINE SOFTWARE Wow6432Node Citrix CtxHook AppInit_Dlls Smart Card Hook [64-bit systems] Windows Smart Card Service Make sure the Windows Smart Card service is started on the virtual desktops or all of the above will have no effect. Tested Platforms and Devices I have tested this configuration with Citrix XenDesktop 5.6. The virtual desktops were running Windows 7 x64 with the XenDesktop VDA 5.6.200. Smart card readers tested were Reiner SCT cyberJack e-com and Omnikey CardMan 3121.
