XenDesktop 7.6 - Missing USB event log info
Article ID: CTX215288
Updated On:
Description
In XenDesktop 7.6, the Citrix USB service has been deprecated, instead there is Citrix Device Redirector service that took over that functionality.
However the new service doesn't produce any event logs related to USB rules and activities.
Environment
Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
Resolution
Add related event log logic to icausbb.sys, which will now enable you to write windows event log.
Original USB redirection events are now available in “System” with Source “icausbb”.
LC5035 bug id fixes a regression whereby the USB token replaces the serial number since VDA 7.6 FP3 and VDA 7.7
To address, add the Product ID or Vendor ID pairs to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\icausbb\Parameters
Name: UsingSerialNumberDevices
Type: REG_MULTI_SZ Value:

Problem Cause
The USB redirection logic changed from ctxrdr.exe to icausbb.sys so the code at ctxrdr.exe that used for writing Windows Event logs doesn't works.
