#12855 obsolete Change to using raw disk access by default for USB mass storage devices Pedro Côrte-Real
Description

USB 2.0 support tends to be buggy and USB 3.0 doesn't exist yet. For mass storage devices a better option is to let the host device handle the USB side and then pass on the raw block device. Today when attaching a USB drive on a Windows 7 host to a Ubuntu 12.04 guest I got (on the guest):

$ sudo hdparm -t /dev/sdb

/dev/sdb:

Timing buffered disk reads: 10 MB in 3.46 seconds = 2.89 MB/sec

After fiddling with the command line and instead letting the Windows host do the USB and passing the raw disk to Ubuntu:

$ sudo hdparm -t /dev/sdb

/dev/sdb:

Timing buffered disk reads: 92 MB in 3.03 seconds = 30.41 MB/sec

This is the USB2.0 maximum. If the port supported USB3 (like the disk did) I'd get even higher speed.

This would make a much better default mode of operation if the GUI supported this mode natively and if VBox handled the plug/unplug gracefully. As it stands if you unplug the device the Linux guest just sees SATA errors and you need to reboot it to get the device back. It would make sense to make the virtual SATA controller support hotplug properly and use this for all USB mass storage devices.

#10406 fixed Changelog between VirtualBox 4.1.2-77218 and 77245 Artem S. Tashkinov
Description

You have silently updated VirtualBox 4.1.2 packages on your website from revision 77218 to revision 77245.

What are the changes between these two revisions? Do I need to redownload and reinstall VirtualBox?

#8196 invalid Changes in VirtualBox webserver broke the virtualbox-plugin for Hudson Michael Mzik
Description

Changes made from VirtualBox version 3.2+ to 4.0+ broke the virtualbox-plugin for Hudson. I highly suggest that you ensure compatibility, because a) both products Hudson and VirtualBox are made by your company and b) the virtualbox-plugin for Hudson should be considered as a key-plugin!

I created a issue on the Hudson-side too, please see here: http://issues.hudson-ci.org/browse/HUDSON-8634

When Hudson (or to be precise the virtualbox-plugin) tries to connect to the VirtualBox-webserver (4.0+) the following exception-stack is dumped:
