#18555 invalid Virtualbox 6 - vboxadd.service -> please use forums FlowXP
Description

Hello, I use Virtualbox a lot because it gives me the freedom to try anything without worrying that I broke my OS. But that stopped ever since VB version 6. Since than my shared folders broke.

First of all this issue can be reproduces if the guest is Manjaro Linux and the Virtualbox version is at least v.6. It's the same if the host is Windows 7, 10 or Linux Manjaro. Also this problem does not occur if the guest is Linux Mint for example. From this I understand that the problem is in Manjaro but on forums I cannot find any solution. Including my post there : https://forum.manjaro.org/t/virtulbox-host-w10-guest-manjaro-kde-share-folders/78754/5

Until VB v.6, on a new guest I have always followed this 4 steps the share folders between host and guest.

  1. Install headers on guest
  2. Install Virtualbox from Guest Additions CD Image in guest
  3. include my user in the "vboxsf" group
  4. Restart

and voila ! I had acces to the Media folder into the guest

After v.6xx it only works if I try like this

  1. linux419-headers 4.19.28-1 and linux419-virtualbox-guest-modules 6.0.4-10
  2. Insert Guest Additions CD Image… → “autorun.sh”
  3. User Accounts → vboxsf
  4. Restart
  5. media → “Ownership on Active User&rdquo”
  6. Insert Guest Additions CD Image… → “autorun.sh” again !

After this, 99% work fine, except I get the 2 minutes waiting time when restarting the guest because of vboxadd.service. And if I disable the service, I cannot change the resolution from the guest, bigger than 800x600. But cliboard and shared folder are working.

Also I'm kinda still a newbie in linux world so I don't know what should I try next. Can you point me in the right direction maybe ?

#11883 obsolete VM Crash when inserting CCID Smart Card Floyd21_fr
Description

Hello everyone,

Problem: VM crash when inserting a specific CCID smart card reader
Smart Card model: Weneo SIM http://www.neowave.fr/en/weneo_std_pass_sim.html
Host: Ubuntu 13.04 64bits and Windows 7 64bits

Guest : Tested with Ubuntu 12.04, 12.10, 13.04 64bits, Debian 7.1 64bits
There is no problem with Ubuntu 11.10 as guest
VirtualBox version tested: 4.2.10, 4.2.12, and from SVN

The VM crashes when the Smart Card is inserted and if pcscd daemon is launched. If not, it doesn't crash. As soon as pcscd is launched, the VM crashes 5s later (aborted).
The VM doesn't crash with other smart card readers (such as Gemalto USB Shell Token V2).
PSCSD and libccid have been used with the official packages (stable) and compiled manually.
A lot of combination have been tested.

We have been able to detect the problem and produce a workaround:

The log in /var/log/syslog gives us a clue:

Jun 17 11:22:49 ubuntu kernel: [233678.352861] EMT[16311]: segfault at b0 ip 00007f75f81ed9c9 sp 00007f75fabe1a30 error 4 in VBoxDD.so[7f75f80f9000+230000]

When using gdb:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7fd3d1ce3700 (LWP 26958)]
usbProxyLinuxUrbCancel (pUrb=0x7fd3c835abe0) at /home/florent/vmware/vbox/src/VBox/Devices/USB/linux/USBProxyDevice-linux.cpp:1919
1919        if (pUrbLnx->pSplitHead)
(gdb)

So the problem comes from USBProxyDevice-linux.cpp line 1919.

The problem is that when using a Weneo reader, the struct pointer pUrbLnx is NULL...

Attached three files with an extract of the debugging using gdb:

  1. debug_gemalto: output when using a reader which doesn't make the VM crash
  2. debug_neowave: output when using a Weneo reader which makes the VM crash (notice the pvPrivate pointer which is NULL)
  3. debug_neowave_FIXED: output when using a Weneo reader with our patch

You'll also find these files:

  1. The VBox.log file
  2. The core dump file

These files have been produced using the VirtualBox source code from the trunk branch but it will also work with the 4.2.12 version.

We've been able to fix the problem by applying the attached patch (updateUSB.patch) to the file USBProxyDevice-linux.cpp

Regards

#14834 obsolete Can't use scanner with USB 2.0 Floyd21_fr
Description

Hi,

I am using version 5.0.6 (but also tried 5.0.10) of VirtualBox with a 64 bits Ubuntu guest on a 64 bits Ubuntu host, and with the appropriate version of the VirtualBox Guest Additions installed. I have to use a scanner within VirtualBox, which uses USB 2.0 bus, but enabling 'USB 2.0 (EHCI) Controller' in guest parameters does not seem to work properly. In order to test the scanner, I use xsane to scan a document.

Selecting 'USB 1.1 (OHCI) Controller' works perfectly : the document is scanned then saved in a file with the chosen extension.

When selecting 'USB 2.0 (EHCI) Controller', scanning begins but blocks after a while, it ends with an error message on device I/O. It seems that data transfers suddenly stop, control type transfers are then sent 3 times each 10 seconds, as if the device was not connected anymore. I've tried with the latest version 5.0.10 of VirtualBox but I get the same problem.

Are there recommendations on scanner use with VirtualBox or particularly USB 2.0?

Thanks
