We had been using USB passthrough use a USB hard drive with a VM. The machine was properly rebooted after all VMs were shut down. Once the server came back up, we powered up our VM which we were using the USB hard drive with and found that we had no USB hard drive available.
We checked settings within vSphere, all are correct, vSphere does not see the USB drive or any other USB drives plugged in. We logged into the machine using SSH and tried to get output of lsusb but since ESXi uses a custom version of busybox, that command is unavailable.
Other USB devices are working on this server (keyboard & the USB key that ESXi is installed on)
How can we get USB passthrough working again?
