virtualbox passthrough is not working

[asgard2]

Hi,

I use an xp guest on virtualbox with burning programs, since I upgraded to 14.04, operations like erasing or burning are not possible anymore, no matter what software I use.

It it seems to be an upgrade, I checked the virtualbox settings and upgraded guest addons, but it does not help.
After initiating burning, the drive is trying to do something, but nothing happens, the vm freezes.

Passthrough is still working at ubuntu 12.04 with current upgrades (virtualbox 4.1.12).

Tested with:
lubuntu 14.04 64Bit 3.13.0-24-generic - not working
xubuntu 14.04 64Bit 3.13.0-24-generic - not working

ii virtualbox 4.3.10-dfsg-1 amd64 x86 virtualization solution - base binaries

UPDATE:
I checked the virtualbox version from virtualbox.org, same problem here.

At the virtualbox log, I found passthrough errors:
00:00:20.059735 PIIX3 ATA: LUN#2: CD-ROM passthrough cmd=0x28 sense=5 ASC=0x21 ASCQ=0x0 VERR_DEV_IO_ERROR

The problem only exist with an emulated IDE drive (passthrough).

If I try win 7 and an emulated sata drive, the drive is working.
