I installed the VMware tools within Mac. Since then any USB external storage drive that was once recognized is now not recognized. In Driver Manager I receive this message unknown device.

I been trying to tackle this issue and I have not found a solution to it. Everything works perfect when I loaded Mac OS Lion on VMware Workstation. But now my plug and play devices and USB storage bays are not recognized. I think it happen after I installed the VMware tools within with Mac or there is an issue with VMware drivers. What should I do to go about this without disturbing my current state of Windows. My keyboard and mouse are working fine but all other USB devices and external devices are not. I receive an Unknown device when I plug in a external hard drive via USB ports in Windows or Mac.

Does anyone know how I can fix this?

"Unknown device" where? as a dialog box? What is your host? What is your guest? I'm very confused. –  jnovack Apr 5 '13 at 13:54
it may have something to do with the virtual machine "takeing" usb devices for itself, try looking in wmware settings for options regarding how wmware should treat usb connections –  flagg19 Jun 7 '13 at 15:32

As Flag19 mentioned, it will be a problem within the settings of VMware, i had a similar problem with virtual box but it was pre-disabled to take them over completely, i found out that i lost the use of my webcam for example on my main system because in the virtual system i had allowed a feature to use the webcam, little did i know at the time it meant completely take over the USB webcam functionality and make it not visible on the main sysyem.

I hope you solve your issue.
