Again problems with usb

[angman]

Hi, after upgrading to VB 4.3.18 and installed the 4.3.18 extesnsion pack and update the guest addition. I cannot use anymore the usb 3 external hd.
The host system is Ubuntu 12.04 64 the guest is windows XP 32. The hd are correctly detected and i can see them under the use device menu. But after checking them windows says usb device not recognized. This happen plugging the device on a usb3 port. If I use an usb2 port all work succefull.

On the previus version of Vb all worked good.

VirtualBox doesn't support USB3. Use the USB2 port.

Why on the previous version it worked also using the usb3 ports?

It didn't. Unless you made a shared folder to point to a USB3 drive. The other possibility is you had a USB2 drive plugged into a USB3 port.

I looked at your post about USB from a year ago or so. In that case there was an issue with plugging a USB2 drive into a USB3 port. But USB3 drives are still not supported in VirtualBox.

Yes but after a couple of new release they worked. If I remember correctly were used as USB2

exactly. USB3 drives run as USB2 drives when plugged into a USB2 port. USB3 drives run as USB3 drives when plugged into a USB3 port. You can plug a USB2 drive in either a USB2 or USB3 port. VirtualBox does not support USB3.
