mac host, windows10 pro guest, when i turn on usb2.0 prot, the virtual box can't work

[wanghaiwin]

I have a Mac OS(10.12.6 ) host and windows 10 pro guest VM(via virtualbox 5.1.26). After install the Oracle_VM_VirtualBox_Extension_Pack-5.1.0_RC1, i can turn on the usb2.0 port. Unfortunately, when i restart the windows, the VM crashed. Below is the error message.
//
The device helper structure version has changed.
If you have upgraded VirtualBox recently, please make sure you have terminated all VMs and upgraded any extension packs. If this error persists, try re-installing VirtualBox. (VERR_PDM_DEVHLPR3_VERSION_MISMATCH).


Result Code:
NS_ERROR_FAILURE (0x80004005)
Component:
ConsoleWrap
Interface:
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
//

Hope someone can give me some suggestion.

Best wishes

After install the Oracle_VM_VirtualBox_Extension_Pack-5.1.0_RC1

You have NOT installed the matching Extension Pack for Version 5.1.26

That would appear to be an ordinary error message, not a crash.

As to the cause, your description is either badly worded or it's what erdeslawe said.
