Any way to tap into USB internally in a Mac Pro?

I have a 2008 quad-core (not a 8-core, mine's a "CTO") Mac-Pro. An outfit called Koutech Systems makes 8-port RS-232 PCI-e cards. Problem is, it needs to tap into a USB header-pin connector on the mother board, or plug into an internal USB port. I think it grabs power from the PCI-e bus, and converts the usb serial into RS-232 serial (I know the card shows up as a usb device in system profiler). Is there a way to gain access, internally, to a USB port, and if so, how?

Kinda hate to have to buy a 5-port USB PCI-e card when I already have numerous unused USB ports on the outside. There is a (not easily accessible - ya' gotta pull the front panel fans to get to it) pin-header connector on the motherboard that is labeled "FP-USB" so I'm guessing that means "front panel USB" -- it goes to a small PCB that has the front panel USB and firewire connectors on it -- I wonder if I could hijack that, at the expense of rendering the two(?) (not sitting in front of that computer at the moment) front panel USBs inoperative, but not affecting anything else on that PCB (i.e., the 1394 FW ports or the audio port)?

Is there any way to hook into the SQL report pagination process?

I have a SQL report (based on EMP) with a radiogroup row selector.
The scenario 1 and 2 are in place
1) When the employee row radio group is clicked the P900007_JOB the text item is populated with the JOB for the employee.
2) When the page is initially displayed or submitted via the button the first row’s radio group is programmatically clicked and therefore populates the additional job information in P900007_JOB
Info (radio Group) Employee No Name
(+) 7369 SMITH
() 7499 ALLEN
() 7521 WARD
P900007_JOB CLERK
1-3 Next>
Once the report has been displayed and the next or previous pagination is used then none of the radio groups will be selected and the data in the P900007_JOB text item will still display the job of the last selected employee row.
What I require is on pagination some sort of mechanism to either
a) Call the page_init() that should then set the first row as selected and populate the text item via the programmatic click. (preferred option)
b) OR blank out the additional text item P900007_JOB.

Anybody any ideas? Should I be looking down the route of using my own pagination buttons and adding my code to this?
There seems to be a routine $a_report that I can use for the pagination but I am finding it difficult to get the current first and last record values that I would need to pass. I've seen references to below in the form but when I'm using partial refresh they do not seem to change.

Is there any way to sync notes from iPhone 4 to MacBook Pro?

Is there any way to sync notes from iPhone 4 to MacBook Pro?

If the phone doesn't power on and isn't seen by the computer then you wouldn't be able to pull data off it with the USB connection to your computer.
You could pursue data recovery if the notes are very valuable, but the cost can be similar to having data recovered from a failed computer drive(possibly prohibitively expensive).

The backup of your iPod Touch would include your camera roll photos. Restoring the backup to another iPod Touch or iPhone would recover them. Photos will not be restored by restoring the backup to an iPad.
Note: Apple deletes iCloud backups after 180 days of inactivity so be sure to do this before then.

The best way to get 5.1 sound out of Mac Pro

Hello. I'm not sure if this is the right place to ask this, but could someone recommend me the best way to get 5.1 sound of a Mac Pro. Since I don't require hi-fi -level sound, just simple directional audio for gaming and such, I wouldn't like to pour a lot of money to this. As I see it, I'd need an external sound card, internal PCI-E soundcard or speakers that have an optical input. I would like for the cost to be in two digits, euro or dollar.
Any suggestions about hardware?

Once again, the issue of 5.1 w/Apple comes up.
Here is the bottom line.
You will only get 5.1 audio if the following conditions are true:
- You are using the OPTICAL output on your Mac
- You are playing a DVD with a 5.1 soundtrack
That's it. The simple truth is, that even if you have a Z-5500 setup (like I do), you still will not get 5.1 surround in ///any/// applications other then while playing a DVD.
There is no way to get 5.1 out of a game on a Mac Pro. No matter how much money you throw at it. The support simply is not there. It is not a software issue, it is not a driver issue. It is the game developer's issue (sort of), and it is a //lack of hardware// issue.
The complex truth, and I will attempt to explain, isn't that simple.
Your Mac Pro or Macbook only has a single line-out, that supports 2 channels at the maximum. Optical audio will only handle 2 channels as well- it's the same signal (in two channels) on a different medium, basically.
All PC soundcards that support proper 5.1 (save for a select few) have //multiple// line-out jacks for Front Left/Right, Center/Sub, and Rear Left/Right (3 plugs total for 5.1). Since your Mac/Mac Pro doesn't have this, you can't hook up a 5.1 speaker set and expect true 5.1.
You do have optical audio, however, this only works in 5.1 when a Dolby Digital signal is piped through the optical cable.
Dolby Digital works by encoding a 5.1 signal as a data stream, sending it to a receiver, where it is decoded and played back as 5.1 stereo. DVD's have this audio pre-encoded on the disk.
If you wanted 5.1 output from your games, they'd need to ether have the sound/audio data encoded as Dolby 5.1, or support encoding on the fly to take a 5.1 signal, encode it, and pipe it out the optical audio plug. Xbox360 does this, because they've licensed the technology from Dolby- as have the game developers.
Unfortunately, none of the developers for Macintosh gaming have yet to include live Dolby 5.1 encoding (I think Doom 3 had a beta patch that did- I could be wrong).
If the game doesn't support the above feature, then you only get basic 2 channel audio.
*Do not buy a Fireface 800.*
This is a professional audio interface (like an external soundcard). While it supports 5.1 output via 6 individual outputs, you need SPEAKERS that have +built in amplifiers+ (called a Studio Monitor). Not just one amplifier- all the speakers have it built in and take a balanced stereo input.
You're looking at $1300 for the Fireface 800, and another $200 per speaker. This is not cheap, is not meant for gaming, and is not consumer grade equipment. It's pro audio, designed for Logic 8 and similar.
Even if you did spend the money, trust me, I'd know... I have a 5.1 setup running through an Apogee Ensemble (a $2000 "soundcard"), and I do not get 5.1 support from Quake 4, C&C 3, or any other game. I only get 5.1 surround from my audio production in Logic 8.
To recap, since this has been asked many times- and I don't want you wasting your money here (just trying to be helpful!)...
*There is no simple or cost-efficient way to get 5.1 from your Mac, other then while playing a DVD movie.*
I would highly recommend that you buy a very good pair of 2.1 speakers with a Sub woofer. Maybe even a pair that takes an optical input for audio. If you really want to spend the money to *watch a DVD in surround sound,* then you can... And it'll work wonderfully, but gaming will not give you surround sound at all.
*Again- There are no games out that support 5.1. Just because you technically support Dolby 5.1, doesn't mean the applications are aware of it and can utilize the 5.1 surround.*
Edit: I may have neglected to also mention that the Firewave unit will support 5.1 properly through 3 separate plugs (much like a PC soundcard does), however the only game I am aware of that supports this is Unreal Tournament 2003 for Mac (or was it 04?), with an experimental patch for 5.1 via OpenAL. Last I heard, it worked okay, but crashed occasionally.
Most of the other games out there just don't support 5.1, period (probably due to the lack of hardware on the Mac computers from the factory).

I have a belkin 7 adapter for additional USB slots for my Mac Pro. It was working well till just recently I am getting a message that says the usb port on the Mac Pro is shutting down due to a very high power drain. Then it shuts the usb port down.

I have a belkin 7 adapter for additional usb ports for my mac pro. It worked fine without problems till recently when the message regarding usb port drawing too much power and the computer shuts the port on the mac pro down. The strip comes with its own power supply adapter. The attachments are additional hard drives used as backups and independent data. Other than disconnecting it are there any fixes?

You're getting the message because you're exceeding the available current, probably as a result of bus-powered drives. The power sources for hubs are rather small. Try using drives with their own power supplies.

I need lots of USB ports with New Mac Pro, now what?

because I'm in the audio business I needs lot of USB ports with my Mac Pro. On my current 2008 machine, that's not really an issue, with 5 ports on teh MP itself and I installed some USB hubs over PCIe that give me a total of 13 port. I'm not really sure what is the best way to get that amount on the new MP.
Oh, and I really like the stability of my current set up. Before I went with an external USB Hub that always gave me headaches with ports not being recognized.

The only two things I found so far are:
a/ going back to the external USB hubs, which I find very frustrating to work with, because instable with connection and I would need to add some interface to go from USB to TB (which are also rather expensive at the moment)
b/ use some external PCIe enclosures that are really expensive.
So I havent really found the right solution for my situation. Which makes me hesitant to migrate to new MP at the moment.

Booting from USB 3 on a Mac Pro 2010

Two issues: I've been looking for a USB 3 Card for Mac pro without much luck. Therefore, any suggestions for a good, reliable card would be much appreciated. One piece of information I came across is that apparently USB 3 does not support booting from an external drive(Clone), but not sure if this pertains to a MacPro 2010. Can anyone verify this information? I assume eSATA does support an external bootable drive, but I may be wrong on that. Again, any info would be appreciated.
Thank you,
Gary

I have the CalDigit USB3/eSATA card in my 2010 Mac Pro. It works well; however, drives attached to it are no more immune than any other external drives to the Improper Disk Ejection bug that occurs with Mountain Lion, Mavericks and Yosemite in the process of sleeping/waking from sleep. Apple is apparently never going to fix this. In Snow Leopard, any drive attached to the CalDigit card behaves perfectly. I have never tried booting from the eSATA interface.
BTW there is a CalDigit FASTA-6GU3 USB3 eSATA card on eBay right now:
http://www.ebay.com/itm/201264131915?_trksid=p2060778.m1438.l2649&ssPageName=STR K%3AMEBIDX%3AIT
I didn't see any mention of which card it is. The first version works with OS 10.5 and newer; the second-generation card requires 10.8.2 or newer.
I have experimented with the Mountain utility on my Yosemite test drive, and with Mountain running, the improper ejection problem has so far not occurred. But I spend little time in Yosemite, so I am not 100% positive that Mountain has solved the problem.

I have just recently bought a MacBook Air. I am looking for an email which I put into a folder on my Mac Pro. The smart folders have come across to the Air, but not the 'On my Mac' folders. Are they lost?

Are you sure that the "On My Mac" folders weren't empty? If all your mail accounts are IMAP, they may have been.
