We have a Windows 2008 R2 Server running on VMware ESXi 4.0 with RDS and I don't get the USB redirection to work properly.
SRSS is 5.2.1 (latest). Sun Ray Components are 2.4 (bundled with SRSS/SRWC).
First of all, the driver of the utSrServerBus Device is not installed correctly (it seams to because of the Windows Driver Compatiblity Check). The Device hast a yellow warning "!" in the Device Manager and says (Code 52).
The driver was signed wrong or the file is corrupt. I've reinstalled it several times now. Watching the driver file (inf) properties I see that it is signed by Oracle (and by Versign).
I think this also leads to that the utSrServerPort is not installed.
As a workaround I installed the SR Components from SRSS 5.1 (version 126.96.36.199) which seem to work correctly.
This has been reported previously. And seemed to be specific to VMware installations running 64bit guest OSes.
It was found that having a virtual USB stack in the guest VM settings would trigger this problem. As thsi is not needed for the SRWC windows components to provided USB redirection, we were able to resolve this by simply removing the virtual USB device stack in the VM and reinstalling the SRWC Windows components software.
