Hi,

I have a case with VMware regarding issues with USB Redirection and Horizon Agent 7.9 (also tested Horizon Agent 7.8). We also use UEM 9.7.

The solution was to add this registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\USB]

"WaitForSessionIdTimeout"=dword:000000c8

Where 000000c8 is HEX for 200 in Decimal.

In our case, UEM disabled USB because of a default timeout of 60 seconds:

DEBUG (0C88-1588) <MessageFrameWorkDispatch> [ws_vhub] USB is allowed by GPO

DEBUG (0C88-1588) <MessageFrameWorkDispatch> [ws_vhub] UEM is installed

DEBUG (0C88-1588) <MessageFrameWorkDispatch> [ws_vhub] Can't get a valid sessionId within 60 seconds for channel 0x000002878977E5C0. Already closed?

INFO  (0C88-1588) <MessageFrameWorkDispatch> [ws_vhub] USB policy set to disallowed

The registry increases this timeout to 200 seconds, which was enough for us in this case.
