Well, another important piece of information from VMware to those who have a plan to upgrade their vSphere environment to v5. Please bear in mind that View 4.x currently is not supported in v5 and failing to do so can cause View pools disastrous. Please make sure you upgrade your View infrastructure to View 5.0 first prior to v5 upgrade.

I’ve just read the KB and it may be useful for those who want to upgrade their ESXi to 5.0 version via VUM. At the same time this can be a perfect reference for me before upgrading any of my customer host which is having vusb device. Though this will ONLY cause your upgrade fail, we can save few hour for troubleshooting by disabling first virtual usb ethernet device before we perform the upgrade.
