[solved] VirtualBox and USB

Let me understand something - VirtualBox OSE does not support USB and the only VIrtualbox for Arch is the OSE version which even after installing virtualbox-ext-oracle does not support USB.
WTF?

"If USB is not working on your Linux host, make sure that the current user is a member of the vboxusers group."
If I wasn't, I wouldn't be able to run the VM anyway, right? Anyway, the user is added.
"The rest of this section only applies to those older systems"
My OS is brand new Arch and my hardware is top-end C2D with new bios so I don't think that applies.

[SOLVED] Virtualbox and USB Support

I use Virtualbox quite regularly for work and school. I have Windows installed within Virtualbox, and I use it whenever school or work requires. However, USB support has never worked for me (even with the fstab addition) and I thought maybe I'll spend some time to figure this out.
Basically, I may want to do things like insert a flash drive and make it available to the VM, or even sometimes an MP3 player or even my PSP. Unfortunately, it doesn't seem to work. There USB filters, but often times the device I want is greyed out, and can't be selected. When I am able to select a device to create a filter, it doesn't do anything. I did check the Wiki already.
Maybe I'm missing something? Or is USB support in Virtualbox just that bad? I was hoping there would be some sort of way I can dedicate a USB port to Virtualbox, and make it exclusive. I think VMWare can do that but I'm not sure that Virtualbox can.

I hope it's ok to post in this thread because if I started a new thread the title would be identical. I am also using virtualbox_bin from AUR and while USB passthrough works just fine to my Windows XP guest, it can't be working any faster than USB v1.1 speed. I have the appropriate entry in /etc/fstab and am a member of the virtualbox group. No permissions problems and from what I can tell there's no corruption of data to/from any of my USB flash drives. The only issue I've had other than the aforementioned lack of speed is with a 1TB Western Digital Passport. It seemed to have "lost" some directories. In other words they appeared completely empty on the XP side. After shutting down the guest I verified that all of the files were indeed still there and intact. I've basically chalked that one up to a deficiency in Windows XP. But this speed issue is seriously holding me back.

[SOLVED] Virtualbox and screen resolutions...

I'm not sure if any of the following updates could have done it but the auto change resolution feature in a Virtualbox Windows guest has suddenly stopped working... I tried reinstalling virtualbox and extensions and reinstalling the virtualbox drivers in windows but it doesn't work for some reason. Any one else experience this lately?
Thanks!

No dice... I did all that and still doesn't work. Do you think gnome3.2 has something to do with it?

fowler,
I don't have problems with auto change resolution and my system is up to date, particularly xorg (not gnome, i don't use it).
However I don't use virtualbox-bin (I did, in the past), I don't think its needed anymore.
I have installed:
virtualbox 4.1.4-2
virtualbox-additions 4.1.4-1
virtualbox-ext-oracle 4.1.4-1 (from aur)
and then installed the guest additions, which should be enough.

[SOLVED] VirtualBox 4 & USB Host

I'm moving from Virtualbox 3.x (binary PUEL edition with USB from AUR) to 4.x. My 3.x was fully working including USB host.
I've uninstalled Vbox 3.x and installed the following packages:
- virtualbox 4.0.0-2
- virtualbox-additions 4.0.0-1
- virtualbox-ext-oracle 4.0.0-2
Extension pack shows up in Virtualbox extension manager (USB host). I've also installed guest additions and enabled USB host under VM's configuration. However I'm unable to select any of my USB devices (everything is grayed out). Is there any additional step to go through in order to get access to USB devices.
Thanks
Alphazo
PS: From my previous working 3.x installation I also have my user belonging to the vboxusers group and vboxdrv module loaded by rc.conf.

According to the wiki it is no longer required to mount usbfs by modifying /etc/fstab (although you need HAL to be running).. Again I had USB host working fine with VirtualBox 3 PUEL edition. I since moved to VirtualBox 4 (GPL) + extension pack for USB (PUEL) but can't get USB to work. I'm not sure the package virtualbox-sun can solve my problem.

[SOLVED] Virtualbox list usb devices is empty.

I moved from virtualbox_bin(AUR) to virtualbox(community), and remove /proc/bus/usb entry in /etc/fstab, after that the usb doesn't work. I can check 'Enable USB 2.0 (EHCI) Controller' in Virtualbox settings, but can't find any available usb devices.

Have rebooted and reinstalled virtualbox multiple times to no avail.
It is important to note that my iPhone used to sync with iTunes on Windows 7 in Virtualbox, but then I removed the USB filter and did some updates and now it no longer works.
I have spent many more hours than I care to admit on this problem, so please, any help is welcome.

No. There is no need to go to a command line and there aren't any DOS commands that will help.
You should consider using Windows system restore to return your notebook's operating system to a date before this issue began. Choose a restore point dated before the problem surfaced.Use the search charm and type in restore. Choose create a restore point. The System Properties window will appear. Click on System Restore as seen in the following image.
Make certain the show me more restore points option has a checkmark in the box. Choose the restore point that you want and then click on next. This is safe and reversible.

I'm not able to copy and paste files from my mac to hard disk and usb. I have tried dragging the items to those devices but it won't work. I also have tried copying and pasting those files onto those devices but that doesn't work too. Can any one help?

Hi BobRz
Thanks for you suggestion but it didn't work - are there other ways for solving this problem? Or is it because my files that I want to copy and paste onto my hard disk etc are too big? (However there is space on my hard disk and it works on a PC)

Thinkpad W520 with Minidock+ Series 3 - Dual monitors and USB fail sporadically

Hello there,
I wonder if anyone has experienced problems ThinkPad W520 and Mini Dock Plus Series 3 (Part number: 433830U)? I run into problems with dual monitor and USB devices.
For dual monitor setup, sometimes only a single monitor is detected, sometimes no monitors are available in the NVidia control panel. Rigorous display detection doesn't help. Disabling Optimus in BIOS doesn't seem to affect it. After I dock and undock couple of times, reboot, unplug the power cord, it seems to resolve and both monitors work fine.
Also, I run into troubles with USB devices (keyboard/mouse). Sometimes they are not detected at all, but if I plug them into different USB ports on the mini dock, they are detected and work fine.
For me this problem happens about 50% of the time when I dock... Any ideas, insights or suggestions are greatly appreciated. Could it be a faulty Thinkpad, docking station or may be both? I really to upgrade next time to W530, but I've been through so many problems with W520, so I don't know if it's a good idea...
Thanks so much.

If system update isn't finding anything, and the system works just fine on its own, it could potentially be a faulty Dock.
It could be overloaded. Could you try testing the dock using just one monitor, and no keyboard or mouse, to see if you run into the same issue. It would still be a faulty dock, but it may be a potential workaround for the time being.

Need USB to RS232 and USB to LPT adapters

Hi, My Toshiba Satellite A100 has only 4 USB ports. I need parallel (LPT) and serial (COM) ports. How to solve this problem? I have adapters USB to LPT and USB to COM, wich work on my desktop, but they not work on notebook. Thank in advance.

I have read on some sites that not all USB adapters work properly.
You should firstly google around for more informations about such adapters.
If you are sure that it will work so you can buy it.
Anyway, the PCMCIA is a good solution

Stuck on Itunes and Usb Logo after Restoring?

So i updated my iPhone from 6.1.3 to 6.1.6 and did not back it up. After the update, i restore it (Deleting all the files and datas).
And then after the restore, the iPhone is rebooting, then it is again in the Itunes and Usb logo asking me to restore it over again.
I have restore it 2 times, and it is annoying! What to do now? How can i bypass this after restoring the Phone?

Thanks for reply, but the problem still not solved. On iTunes > Devices (iPhone), the message "The SIM card inserted in this iPhone does not appear to be supported"
What the meaning of *only compatible SIM cards*? How to buy or get that card?

LAN card and USB not detected (KM4M-V)

I just formatted my PC yesterday, installing Win XP SP2. But the intergrated LAN card and USB is not detected in device manager. I tried HELP but cannot solve the problem.
I am a little confused. After formatting and installing Windows, the hardwares who don't have driver will be having a question mark icon in the device manager. But for my computer, no USB or LAN card is written in the device manager. How can that be?
I had checked my BIOS and nothing indicated to change the USB or the LAN card.
Where did i go wrong? I am using a MSI KM4M-V motherboard.
Anyone can help? Thanks.

because there are too many spywares in my PC
so was your computer seeming to be sluggish as well then?

NI PXIe-4154 Conflicting Measurements -- Smartphone and USB

I am having some problem to calculate power consumption from android smartphone...
First my setup: Android smartphone is connected to PC with USB. Both smartphone and USB do not provide their own power, but instead, I provide power to them via PXIe-4154. To clarify, smartphone's battery is removed and replaced with probes from ch0, and red power wire on USB cable is cut and end going toward smartphone is connected to probes from ch1 (ground wire is connected as well). Also, ch0 is set to 4.1V and ch1 is set to 5V.
My problem now is to try to find right method to calculate power and energy usage in this setup for smartphone alone (without effect of USB). My initial calculation of power and energy (with USB connected) turned to be wrong when I tried to perform same measurements without USB (ch0 only) (which were different by a good degree). I still hope I can try to calculate corrent power that is used by smartphone alone based on current configuration (and current samples that I have). (I am using USB mostly because of convenience, since it allows me to control android smartphone with ADB commands, over USB).
Here are some of my measurements (with USB and without, which conflict): When I have USB connected, idle current from ch0 is -0.28A and active current is -0.1A (when I run my test task). At the same time, idle current on ch0 is 0.37, and active current is 0.405A. When I tried to perform same measurement without USB (I sent command for the task over wireless connection), my idle current on ch0 is 0.022A and active current is 0.28A. What I can't understand is why I seeing difference in delta current (0.17 + 0.035 vs 0.258).
Also, when I turned off the phone, currnet on ch0 is -0.345A and current on ch1 is 0.382A.
I am not sure if my PXIe board is configured incorrectly, or why would I get such conflicting results. Could anything give me some advise what I could try to do to solve this?

Hi armendhz,
I have a few questions that may help clarify your situation for me.
1) Where are you getting your current readings?
2) How are you measuring a current when the phone is turned off?
3) Do you have any other PXI modules?
4) Can you attach a schematic of your connections for me?
Hopefully we can get to the bottom of this soon.
