Error opening uuid generator

Hello,

I am seeing an "Error opening uuid generator" error when attaching USB devices on a client.

The host is Ubuntu 20.04 (in chroot), and the client is Windows 7. The client is actually a VM running in Virtualbox on the same machine.

Besides the error, things seem to function normally except for a few random server ping timeouts and disconnects, which is odd considering that the server and client are running on the same machine, communicating via a Virtualbox "host-only" virtual network interface. My theory is that the random connectivity losses are due to random latency spikes, but I'm still looking into it. I think it's more of a network issue rather than a Virtualhere issue. Perhaps I need to increase the priority of the Virtualhere process or something. Anyway, the log is below.

Does the uuid generator rely on some file in /dev or /sys?
