No Solaris client USB access

[spbarrett]

Since upgrading to VirtualBox v5.0.24 I can no longer access USB drives from a Solaris client. I have tried Solaris 10 & 11.3, USB HDD & flash, flash formatted in fat32, NTFS, & ext4. I have re-installed the VBox extension. Recreated the VM from scratch. And also tested the error on a Windows 7 host. It appears to be limited to Solaris clients. Both hosts are Intel i5 processors, i have not yet tested on AMD. The USB appears on the host desktop and is selectable via the Devices->USB. The selected device shows a "check" but the client is unable to mount the file. Un-checking the device reconnect it to the host machine. This is new to 5.0.24, it has worked properly in recent weeks with 18-22. I am creating a VM for delivery as a training tool to customers and they will require USB access to complete the training labs.

Downloaded and installed the latest build (5.0.25). No change. It appears that the service for the USB vbox driver is failing to start. Attempted to clear the maintenance flag without any success. Still functions OK for Windows client, just not Solaris.
