<font face="Verdana">Here is a strange issue. <br>
<br>
The USB device works great and I don't seem to have any issues
with the exception to one. I can use the devices tab and remove
the device and it returns to the host as expected, but if you use
the guests release it gets lost in limbo. Not available to the
guest or the host.<br>
<br>
Unplugging the device and inserting again returns the use of the
device.<br>
<br>
Note: I do not use a filter. Always select the USB device from
the devices tab. <br>

I will see about running my debug build tomorrow and see what I can

Are the subtle misbehaviors in Linux as well as Windows?

The main USB breakage (related to locking changes) in trunk was common
to all platforms. The vast majority of fixes are in the common code,
however it was also necessary to make changes to the platform dependent
USB code, so there is a (hopefully very small) chance that platform
specific issues are left. The changes to the platform dependent code
were extremely simple and repetitive across the platforms compared to
the changes in the common code.

I've checked this issue again and now I can reproduce it. No idea

This is indeed a recent regression and will be fixed ASAP, I will
let you know.

<pre wrap="">It should be fixed now (r41528 and r41529) - please report any
noticeably different behavior compared to VBox 4.1 (which wasn't
affected by this trunk only change/regression).
It'd be great if people with experience could run debug builds (both
VBoxSVC and the VM frontend inside a debugger, otherwise triggering an
assertion will lead to a sudden death) and let us know if any assertions
were triggered in relationship with USB operations. Release builds
should still show subtle misbehavior, but debug builds will shout ;)
Thanks,
Klaus

It should be noted that there are no build errors as such except the
normal errors about hard links.

<pre wrap="">It has to be something in the base code.
I installed the latest .deb and it works.
Compiled packed and install the latest tarball (4.1.14) and ExtPack.
and it works.
Compile the latest from SVN. Fails. Says the guest is not running.
(with the latest ExtPacks) from Frank.
Completely purged the build environment and started fresh. So it could
not be a corrupt file. Still failed.
Sorry to say but i don't check USB too often and the first time I
noticed it failed was r41127 but I tried all the way back to r40671
(oldest backup I have) and it fails there as well.

Version = 4.1.51_OSEr41221

I removed VirtualBox& the vboxusers group and logged out.
Installed VirtualBox and it created the vboxusers group again (it

list extpacks = Extension Packs: 1

Version: 4.1.51
Revision: 77890
Edition:
Description: USB 2.0 Host Controller, VirtualBox RDP, PXE ROM with
E1000 support.
VRDE Module: VBoxVRDP
Usable: true
Why unusable:
Try to enable inside the working guest:
Failed to attach the USB device Kingston DataTraveler 2.0 [0200] to
the virtual machine Debian-Buildbox.
The virtual machine is not powered up.
Result Code: E_ACCESSDENIED (0x80070005)
Component: Console
Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}
I will try to go back a few builds and see where it start to work
again, but it is not working now and the funny thing is the report
of the machine not powered up when trying to enable the device in
the running guest.

<pre wrap="">I have no idea. This works here and we didn't change any access

Could you check again if something changes if you use a more recent
ExtPack?
