I thought that it occurred in v 1.6.0 but I reverted to v1.5.2 and it works wonderfully. I am running WinXp SP2 as the host and Win2K as the guest. Tell me if I can provide more info to help with this. I know the issue exists in v 1.5.6 & 1.6.0. I can test 1.5.4 if needed. defect closed USB VirtualBox 1.6.0 fixed USB other other
