Hello,
We're a Horizon 7.10.2 shop utilizing Horizon RDSH to publish Epic Hyperspace (client is 5.5.1). One of the peripherals required is a Topaz BSB Signature pad for documents that require patient signatures. On the Agent side we're enabling USB redirection, and while it works, we're seeing a behavior that implies only 1 user (maybe 2?) per RDSH server can pass in their SigPad. For example if we had 2 RDSH servers in the farm but 4 users, and all 4 users needed a sigpad, only the 1st users on each server would get it. The other 2 would receive this failure when the device is attempted to attach:
When I dump out the logs, I do find these entries:

We have an SR opened with VMware, but, no word yet from them. I'm hoping this isn't expected behavior, that there's a wall you can hit when users are passing in the same kind of device to a single RDSH server.
Our workaround right now is that we expanded the farm to be 20 servers. There's 7 users we expect to need a sigpad at any given time, so, thus far it's been working ok. But as our environment grows, this is going to be difficult to maintain if these devices (or even other USB types) have this kind of limitation.
Thanks in advance.
