URB Flag warnings in log when using USB with VirtualBox

Hi,
I have a VirtualBox VM and an external hard drive which is directly connected to this VM. VirtualBox extension pack is installed and USB2.0 (EHCI) Controller is enabled for this machine.
When I now copy files onto this hard drive (inside the VM) I get millions of the following warnings in my journalctl of the host computer:

The write process seemed to work, but the warnings don't look good to me. What do you think? Can I ignore these warnings? If yes, can I disable them?
I already found some other threads out there, talking about a similar problem, but in all cases, the USB devices did not work inside the virtual machine.
(Yes, my system is up-to-date.)

Kernel Panic when using Garageband with Blue Snowball USB mic

*HI ALL,*
*I purchased Mac Pro recently about 3 weeks ago. I am on the latest updates including the recent firmware update. However whenever I use garageband with external USB mic(Blue Snowball) my Kernel Panics and OS freezes and forces me to Power On again. It happened 20 times so far in few hours.*
*I opened garageband first time today after bought this external mic from apple store. I did not use garageband without this mic plugged into USB, I only used garageband with MIC plugged in and in couple of minutes to 5 minutes of using garageband the Kernel Panic occurs. Need your help please. Here is the message I get after login again which I reported consistently to Apple. Any immediate help is appreciated. I use iMove, iPhoto and other apps without any problem. Harddisk verification went o.k.*

I've been getting a number of kernel panics when using USB Mics with Skype, though I have not experienced any crashes when using Garageband.
The crash report cited the AppleUSBAudio driver as the culprit. Here's the set up:
MacBookPro Core2 2.66 15"
Mac OS X 10.5.2
Blue Snowflake USB Mic, Blue Snowball USB Mic
Skype (latest rev - 2.7.0.257)

Seems to be a lot of crashiness with USB Audio in 10.5.2 - let's hope we see a patch soon

Format and Partition Task Sequence Not Working As Exprected When Using USB Media

Task looks like this.
Had been working on PXE based task sequence, but when I use USB media, it only makes a single partition that is around the size of the USB thumb drive.
How does this need to be changed so that it makes a C drive partition that is 80% of the total local disk space and a D drive that uses the remaining disk space when using USB boot media?

If you choose to create a "custom" partition configuration like the one above, then you are responsible for creating any extra required partitions like a BitLocker boot partition.
Additionally, if you are deploying on a uEFI machine, then you will also need to create the correct uEFI partitions.
Generally I discourage creating extra partitions.

Does Mackie Control work with Final Cut 7 when using USB MIDI?

I have a Mackie Control Universal Pro connected via USB to my mac and it works GREAT with Logic and all the complimentary Logic Studio software.
The problem I am having is, when I try to use it with Final Cut, it wont work at all. I have read the post concerning this that was answered by Andy Mees but, I dont use a true MIDI connection, only USB.
Any thoughts?

Does Mackie Control work with Final Cut 7 when using USB MIDI?
No one will know until FCP 7 is released.

Is it possible that GMail only allows access to untagged emails via POP3? Or only to emails from the last x days?
POP3 is the older email retrieval protocol (IMAP4 is the more current one) and only has very limited support for folders (or anything but a single inbox, really). It's quite common that POP3 only allows access to a subset of all emails stored by a provider.

Best practice when using Tangosol with an app server

Hi,
I'm wondering what is the best practice when using Tangosol with an app server (Websphere 6.1 in this case). I've been able to set it up using the resource adapter, tried using distributed transactions and it appears to work as expected - I've also been able to see cache data from another app server instance.
However, it appears that cache data vanishes after a while. I've not yet been able to put my finger on when, but garbage collection is a possibility I've come to suspect.
Data in the cache survives the removal of the EJB, but somewhere later down the line it appear to vanish. I'm not aware of any expiry settings for the cache that would explain this (to the best of my understanding the default is "no expiry"), so GC came to mind. Would this be the explanation?
If that would be the explanation, what would be a better way to keep the cache from being subject to GC - to have a "startup class" in the app server that holds on to the cache object, or would there be other ways? Currently the EJB calls getCacheAdapter, so I guess Bad Things may happen when the EJB is removed...
Best regards,
/Per

Hi Gene,
I found the configuration file embedded in coherence.jar. Am I supposed to replace it and re-package coherence.jar?
If I put it elsewhere (in the "classpath") - is there a way I can be sure that it has been found by Coherence (like a message in the standard output stream)? My experience with Websphere is that "classpath" is a rather ...vague concept, we use the J2CA adapter which most probably has a different class loader than the EAR that contains the EJB, and I would rather avoid to do a lot of trial/error corrections to a file just to find that it's not actually been used.
Anyway, at this stage my tests are still focused on distributed transactions/2PC/commit/rollback/recovery, and we're nowhere near 10,000 objects. As a matter of fact, we haven't had more than 1024 objects in these app servers. In the typical scenario where I've seen objects "fade away", there has been only one or two objects in the test data. And they both disappear...
Still confused,
/Per

Display "blank-out" when using Maya with a GF 7800?

I have a problem where my LCD display occasionally blinks off for about 5-10 seconds when using Maya with a scene displaying about 100,000 polys. Has anyone else encountered this? This only seems to happen when I am quickly rotating the camera in a grey shaded perspective panel?
My LCD is a Dell 20" LCD (set at 1600x1200) connected to a Geforce 7800 in a Quad G5 with 4.5GB of ram.
I have never seen this issue before in Maya (I have been using Maya for years, on other machines), so I suspect it is hardware or driver related?

OK, have completed several tests. I definately seems that the my Geforce 7800 has problems when running some applications. I wonder if anyone else has encountered this problem?
The easiest way to cause the display to momentarily shut off is to use Maya in the full screen perspective camera window in shaded mode. Proceed to rapidly move a 20,000 poly model (or greater) both zooming and rotating (the polys need to fill the entire screen and shake the mouse).My display (Dell 20" 2001fp) will blink-off for a few seconds. Of course, this in not "normal" work flow, but I have this issue happening when working normally, it can sometimes take time to occur.
I have tried the Geforce 6600 (256mb ver) and this does not occur with that video card. I have tried several mice both wired and wireless, plus changed the Energy Saver options for Processor performance (from comments I read on Macintouch.com). The problem is consistent to my Geforce 7800. This problem will also occur in Photoshop CS, by moving images and resizing, but I found it much harder to induce.

When using pdfFactory with Firefox, why are the colors on the pdf not correct?

The colors are vastly different when using pdf Factory with Firefox. When using pdfFactory with IE, they are both the same.

There doesn't seem to be a one-size-fits-all answer, because what works for one printer doesn't necessarily work for another, and I don't have your printer so I can't advise on specifics...
However, perhaps we can discover a set of settings that will work...
If you File - Print, choose Photoshop Manages Colors, in the Printer Profile section do you see profiles specific to your printer (e.g., with the name Kodak in them)?
If so, choose one of them that seems appropriate given the paper you're using.
If not, try choosing sRGB IEC61966-2.1.
Now, before you continue, press the [Print Settings...] button. This brings up the printer driver dialog. You may have to go through [Advanced] buttons or whatever, but what you're looking to do here is to disable the printer driver's color management logic. In other words, if you can find a color-management / ICC profile handling section, set it to "no color management" or equivalent. OK back out to Photoshop's print dialog, then press [Print].
The key here is that if Photoshop manages the color transforms, the printer driver should not be set to do so - or vice versa.
If you're presented with the printer driver's dialog again, double check that the settings you chose above are still set, for good measure, and try a test print.

How to store a layout, when using CL_SALV_TREE with a container?

Hello,
I'd like to use an object of type CL_SALV_TREE, that is placed on a custom container (and therefore not displayed in fullscreen).
But how do I get the functionality to store a layout, when using CL_SALV_TREE not in fullscreen mode? If you use it in fullscreen mode, you just have to define the function code in your gui status and everything is ok.
But since I want to place my CL_SALV_TREE on a custom container, that method does not work. If I call <my_salv_tree>->get_functions( ) it returns a table, that holds just six entries. So, the appropiate function for storing a layout does not seem to be in the default set of functions, when using CL_SALV_TREE with a custom container. But how do I activate this function?
I already call the functions get_layout() and set_key() - so that shouldn't be the problem. Or is just not possible to use CL_SALV_TREE on a custom container and have the possibility to store layouts?
Kind regards, Lars

s there a way that when using airplay with power point the ATV does not sleep/screen saver frequently???

I have done this for several Titles, using Photoshop and a Layer Mask, that gets "erased," revealing the letters. My Titles were of "handwriting with chalk" on a blackboard, so I could keep the edge of that Layer Mask, looking more like the "chalk." Photoshop also makes it easy to output Layer Comps for each "step" in the handwriting process. IIRC, I did about 5 Frames per Layer Comp on Import, but do not recall if I used an extremely short Cross-Dissolve Transition between those - I intened to do so, but just do not remember if I liked that, or went with just the Still Images? Will try to find that animation, and maybe create a full tutorial of the process. In my case, I also added an SFX of chalk on a chalkboard.
If you have Photoshop, it's really quite easy to pull off.
Now, I do not know if Photoshop Elements has Layer Masks yet, which make it so very easy to accomplish. One could do it backward, where the Text Layer gets Erased, and then one would have their full Image as the last in the sequence, and then the next would have a little bit of the Text removed, then a bit more, then a bit more - going backward, until the "writing surface" is clean. One could also do this with a Transparent Background, so that one saw the Video below, and no actual "writing surface" visible.
Good luck,

Mid-2012 MBP with 27" Cinema Display SCREEN GOES BLACK WHEN USING USB PERIPHERALS IN DOCK

I haven't been able to find any straightforward answer as to why this is happening and it's becoming one of the most infuriating things in my life, impeding my workflow and costing me unmeasurable time in waiting, rebooting, screwing with cables, etc.
I use my MBP as a DAW for multitracking live audio events to ProTools through a digital console where I work. Here's my gear list that I use every day:
Mid-2012 MBP - Yosemite, 8GB, i7 quad 2.5, mechanical hd
HengeDocks dock for my exact model machine - has set-screw jacks for CinemaDisplay power, Tbolt, FW800, USB, USB, SDcard, headphones, etc
USB wired keyboard
Anker 1x4 USB3.0 hub - I have a TimeMachine 1TB drive, 3TB project backup drive, audio interface and MIDI I/O or PT iLok, depending what I'm working on
Magic Mouse (BlueTooth)
Here's what's happening:
SCENARIO 1 - I insert the CinemaDisplay (cD) power connector and TBolt plugs into the dock, tighten the set screws, close the lid of my MBP (already logged into Yosemite & linked with MagicMouse [mM]) and stick the MBP into the dock... everything comes up on the cD and I can go about my day. At this point, I can plug the USB hub into the back of the cD and the system sees the hub & all peripherals listed just fine.
SCENARIO 2 - Install cD powercon, TBolt connector, USB3 hub, USB keyboard into the dock, close the lid on MBP (again, logged in), insert into dock... cD comes up, looks great for about 15 seconds then goes completely blank. No response from key presses, mouse clicks, threats with a hammer, etc. Then, of course, I have to yank the MBP out of the dock, which hard-disconnects the external drives (backup and TimeMachine... good for them, right?) and causes the MBP to flake, thinking it's still in the dock, then not, then logging me out & requiring a password (not a big deal- I deal with copyrighted stuff, so passwords aren't the issue).
***EVEN IF I DO NOT PLUG THE USB3 HUB INTO THE HENGE DOCK, THE cD STILL GOES BLANK AFTER 15 SEC... IT ONLY SEEMS TO LIKE THE TBOLT AND POWER... NO OTHER PERIPHERALS (fw800, USB, etc)***
It seems like the MBP freaks out when the lid is closed and there are USB/FW peripherals plugged in while using a secondary TBolt display as the main output... seems stupid... if I need a closed-lid dock, the MBP shouldn't care what I have plugged in while the lid is closed. I had the same issues with Mountain Lion & Mavericks and now it's being repeated with Yosemite.
My goal in this exercise is simply to free up the USB jacks on the back of the cD for two reasons - #1) from time to time, I have extra things to plug in and I don't want some massive USB 1x8 hub on my desk... looks stupid; #2) the bottleneck created by plugging in the hub to the back of the cD (another hub via TBolt) almost triples the time required to back up/copy files. I move files from system drive to backup drive & back VERY often due to the nature of my job... speeding up this process would greatly improve my efficiency in the matter. Why would Henge create a dock with all the jacks on it to allow someone to plug into a cD that won't frickin work with said cD? Every other dock I've found makes the user stick the MBP on a slanted, goofy-looking stand and have the lid open or something dumb like that... what I have is the setup I need... just need the USB stuff to work while lid is closed and everything from powercon & cD to USB3 hubs will work without making the cD freak out.
Any ideas out there?

Have now taken the 27" display into the repair shop and after 24 hrs got the phone call - "appears to be nothing wrong with it, will check again on Tuesday and let you know".
I can't seem to find anything on the net describing a similar problem. Everything is working fine right now with the Mac Pro connected to the older 20 inch Cinema Display. In fact, everything seems to be working about a second faster.
I was told by the local retailer that Apple no longer makes the 27 inch LED Cinema Display product and the new display, the "Thunderbolt" will not work with my 13 month old Mac Pro.
***??? In 20 years of owning Mac equipment, this is my first major "uh-oh".

K3011w - How disable the touchpad when using USB mouse?

Is there a way to disable the touchpad on the docking keybd when using a USB mouse? It is a real pain typing along and be in the middle of sentence some where else on the page.

hi whippetguy,
Thanks for Posting,
   The touchpad on the dock uses a Windows driver and does not have any special Software to Disable it via shortcut,
How I found to go around on what you need is
With the tablet on the dock with no USB mouse yet
                  Press (Windows key+x) and choose device manager on the list
                        On Device Manager window open mice and pointing device and rightclick disable
This should disable the dock touchpad and Now you can plu in your USB mouse,
Before you unplu your USB mouse after use, Go to device manager again and Enable the device you disabled.
Hope this helps
Cheers!
