Hi Stanley,
I read some of your messages in threads about USB comm in PDA/Smartphones. I just wanted to confirm with you a couple of requirements, as it seems you're the right person to ask to. I am trying to communicate our device with a HTC Kaiser PDA via USB. My OS is Windows Vista 32-bit, the handset's is Windows Mobile 6 and I am using the Mobile module.
The VI, in order to see the miniUSB port on the PDA as serial (VCP - virtual com port), you say that:
1) The PDA has to be USB HOST (or more precisely OTG) ;
2) The VI will see it as serial (I imagine then, there must be a sort of FTDI chip doing this translation USB-Serial - how else could this translation be implemented?)
Is this correct?
I want to test first the communication between the HTC and the PC. Other questions are then:
1) If I write data to the mini USB using VISA to a serial port in the VI, looking at the signals on the CRO, they should look like USB NOT SERIAL correct (after the translation)?
2) If the signals are USB then I will have to connect it to the USB port on the PC. However I quite don't see how I am going to talk to the device, as on the handset side I will have COM ports and on the USB side I will have USB endpoints, which have completely different characteristics. Any suggestions?
3) Let's assume the USB controller on the HTC side has NOT host capabilities. Is not possible in any way that my VI could see the port still as serial and send/receive data (just waiting for a host to power up the line and start the communication)??
4) The INF generator using the Driver Wizard for Windows Mobile 6, together with the VISA API wouldn't work for the case the VI doesn't see the port as serial? And then I could use the VISA interrupt blocks etc...?
As I wrote many questions, if you'd like a phone call could be undertaken to ease things, as I certainly need to clarify those questions..
Thanks for the time.
Best regards,
Edgar Charry

can't sync itunes with iphone via USB, windows 8.1 system

Right click on your device under Portable devices and click on Uninstall and when the uninstaller box pop ups select delete the driver and click OK. Now click on Scan for hardware changes on top of the page and see if you get apple mobile device support driver under USB Devices and if not then disconnect your device from the computer and try to connect it to a different USB port and check also open control panel and select Apple Mobile Device Support from the List and Click on Repair and check. If still the device is not showing under USB then uninstall the following services from your computer.
iTunes
Apple Software Update
Apple Mobile Device Support (if unable to uninstall ignore and move to next)
Bonjour
Apple Application Support
Restart your computer once after the uninstallation is completed and then download latest version of iTunes from http://WWW.apple.com/iTunes/download
Locate the iTunes setup file and right click the file and run the installation file as Administrator and let the installation complete.
Then check if your device gets deteced in iTunes and if still the device is not detecting in itunes then go to device manager and see under Usb if you can see Apple Mobile Device Support Driver and continue with the step. 5 of above given link in my previous post. And if still thedevice is not showing under USB then right click on your device under potable device and click update driver and first check for updates automatically and see under USB if you see the driver now and if not then go back to device under portable device select update driver, let me choose driver from the list, Have disk, browse file in the following location " C://Program Files/Common Files/Apple/Mobile Device Support/Drivers and select usbaapl file and install the same (if you can't find the driver on above location then look for the driver in Program Files(x86) instead of Program files and if you can't find usbaapl then look for usbaapl64 and complete the installation and then restart the computer and check if your device get recognized in iTunes.
Note: when installing the drivers keep the iTunes closed till the drivers installation is completed.

Till my last software update on my MacBook Air I have been able to use my iPhone as a modem via USB. Now it's not working anymore. Other functions via USB are still fine. Any ideas???

Till my last software update on my MacBook Air I have been able to use my iPhone as a modem via USB. Now it's not working anymore. Other functions via USB are still fine. Any ideas???

The Mac was recently upgraded so it is the Mac, or is it?
Looking for a common denominator: I'l start with wi-fi as the common communication medium.
Known:
A) Broken: iPhone —> wi-fi —> Mac.
B) Broken: iPhone —>USB—> Mac.
C) Broken: iPhone —> Bluetooth —> Mac.
D) Working: Mac —> USB —> other USB devices.
Unknowns:
E) Test Mac —> wi-fi —> a non-iPhone router.
F) Test iPhone —> wi-fi —> another wi-fi device.
Given not A, not B and not C either the Mac or the iPhone could be the culprit.
1) E        | F        : Non sequitur (deepens the mystery).
2) not E | F        : The Mac is the common denominator.
3) E        | not F : The iPhone is the common denominator.
4) not E | not F : All heck broke loose.
For case 1: It would be something on the Mac that prevents it talking to the iPhone through three media even though it can talk to other routers over wi-fi. That would be weird indeed, given the iPhone is talking to other wi-fi devices with no trouble.
For case 2: All of the Mac’s intranet media broken (wi-fi, Bluetooth, and wired-USB) and at least wi-fi works on the iPhone. Something weird is going on in the Mac.
For case 3: The iPhone router function is broken. Upgrade the iOS? Test using another iPhone?
For case 4: Throw everything in the trash and start over.

I need your help regarding Macbook Pro with FCS3 via USB

Sorry for the double posting, I need your help...
I am producing an independent TV movie. We are shooting in HDV with a Sony Z5.
Currently I am using a 2007 iMac (1gb) for the FCS3. I am considering buying a Macbook Pro 15' i7, because I need the portability as well as a WD 1TB portable external drive.
Just when I am about to buy the machine I started to read all about the USB vs. the Firewire. What should I do? The MBP only have one firewire port...if I use an USB portable external drive means that I won't be able to use FCS3 properly and that buying a MBP will mean spending money in something that I won't be able to make it work properly??
Thanks for your help!!!!

Hi there,
As Patrick said its Firewire hubs you should avoid along with directly connecting your media drive via USB. USB hubs are fine for connecting peripherals (keyboards, tablets, mice etc). directly connecting USB media drives is not for streaming video due to their method of sending data in packets rather than as the continuous stream that firewire provides. Firewire hubs just seem to cause all sorts of headaches to those that have used them, I cant give you a specific reason other than splitting the available FW bandwidth (someone with more knowledge on this will have to chime in), its more just inherited practice.

Sync droid mini with pc via USB?

Just purchased a droid mini - how do I sync this with my pc via USB cable - to sync contacts, calendar and transfer pics from teh phone to the pc, etc?
I had an HTC previously which came with sync software. I don't use google calendar / contacts - and have no intention of doing so. I simply want to synch the phone with my pc via USB.
Any help would be appreciated.
Thanks

IPad won't charge using power adapter but will charge via USB

I have an iPad 1 that recently stopped charging using the power adapter. "Broken power adapter or cable" I thought and reached for a spare that I have. That didn't work either. The original power adapter however DID charge another iPad without any problems, so the problem cannot be with the adapter or cable.
Now this is the wierd bit - using the original cable plugged into my laptop I get the usual "Not charging" message but the iPad DOES charge slowly this way.
I rebooted the iPad, restarted it in recovery mode and restored the firmware, cleaned out the 30-pin connector port - all those useful bits of advice that you find on the internet but all to no avail. The iPad just will not charge using any of the many original Apple iPad charger sthat I have been able to get my hands on but will only charge on an underpowered USB port!
The 30-pin connector must work otherwise it wouldn't charge via USB. Can there be some kind of wierd internal hardware defect that might cause such behavior?
I fear that if I take a 3 year old iPad to the Apple Store they might just give me their best smile and show me the latest iPads but this old iPad works fine otherwise and I don't really want to replace it.
Anyone got any ideas?

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
And this - Unplug the charger from the iPad and then replug. May resume charging.
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html

Using Airport Time Capsule with an external usb hard drive - how to connect

I have 2TB Airport Time capsule which is connected to my iMac by an ethernet cable and which I use for T.Machine backups - No problems here.
I have an old MacBook Pro running 10.6.8 and which is also connected to my T/C via wi-fi - again no problems.
But I understand I can use an external hard drive via usb cable connected via a powered hub, to the T/Capsule and which I wish to do certain backups from my MBP (I have no wish to update the MBP as it runs certain apps no longer available on the iMac (10.9.2)
Now the problem I have is trying to set it up, the MBP has Airport Utility 5.6.1 and I can’t continue as it says I need a newer version. As I see it, the newer version doesn’t work on the MBP only the iMac.
A catch 22 situation. If I continue and and go to “manual setup” then try update, all I get is “correct the problem before updating” (Allow setup over the internet using Bonjour).
Anyone have any ideas or images that I can view to try and get things going?
I should add that I wish to use my external hard drive not as a time machine backup but only for certain items using say, Super Duper, but am unable to get the disk to mount on the MBP
Alan

I still can't use it the way I was hoping because it then becomes a T/M back-up disk and not a normal usb/firewire disc.
You are first mounting the drive on the desktop, correct?
Not sure what you mean here.
You can drag/drop files normally or copy/paste files to the drive icon on the desktop, just as you would a normal drive that is displayed on the desktop.
Or, double click the drive icon on the desktop and drag/drop files into the open window there.
Tell us the steps that you are using to mount the drive on the desktop. What happens after each step?

Can't print on my F4580 all in one from my MacBook with OSX via usb

Hi Forum,
I have a HP F4580 All-in-one printer/scanner which worked fine on my old laptop with windows vista.
The laptop has now died so i thought I'd try Apple.
I now need to print some stuff off for work but it doesnt seem to produce anything.
It's plugged via usb and its has been setup on the Mac through the System Preferences and Printer & Scanners icon but when you click print on the document you want the little printer icon pops up on the dock at the bottom but the printer never prints anything!!
Does anyone know what I might be doing wrong or if it evens works through OSX.
Please help.
Many Thanks Willow1980

No problem!
I would recommend repairing the disk permissions on your computer by following this Apple document here. Once this is complete, make sure your Apple updates are complete by following this Apple document here.
Now, I would reset the printing system on your computer. Please follow this Apple document here. If your USB connection isn't responding correctly, then follow this Apple document on USB: Troubleshooting Error Messages. I will be looking forward to hearing from you again!

Can I use my iphone4 to play music via USB in Mercedes Benz c class 2012

Using Epson Perfection 2480 with Tiger and USB 2.0 Macs

Actually I couldn't reply to an older post, since it was archived:
http://discussions.apple.com/thread.jspa?threadID=959762
So I tought to simply drop some info here about a few findings I had in the last few minutes.
Downloading and installing driver version 2.65 cured this (avoid the newer 2.77 driver; Epson says 2.65 is for OS9, but I have it here running on a Intel Mac). This will install the Epson Monitor software. Now that's a first trick: make sure all accounts in the computer have that on the login items for that account, that has to start as soon as the computer starts. Install the older Epson software even if you plan to use your scanner with Vuescan or Image Capture, for example.
After that, I still had the same problem here, but it was only on the machine with USB 2.0.
Switching the scanner to the keyboard USB plug (1.1) solved the problem. Maybe an older hub could do the trick if you have, let's say, a wireless keyboard.
Good luck,
Gui

New SLVR with iSync via USB 1.1 cable

I am trying to get my new Motorola SLVR to transfer phone numbers from my address book using USB 1.1 (I have an old tear-drop mac). When iSync is open, it is not even acknowledging my new phone, even when I do a "scan".
Am I out of luck until I get a newer mac?
It transfers songs just fine.
Thanks,
Phil

The Motorola SLVR L7 is supported now as an iSync device using either a USB or Bluetooth interface, but only with iSync 2.1.1 and OS X 10.4.4 or later.
The short answer, therefore, is that you will have to upgrade your hardware before you can install the software required to support your mobile handset.
If you are looking for a low-cost upgrade path, Apple periodically offers refurbished machines [with full year warranties and current OS packages] at about a 15% or so discount off of retail prices. Currently, a 1.9 GHz iMac G5 17-inch SuperDrive-equipped model with a 160 gigabyte drive is available for $ 1099.00. This package is iSight equipped, and includes FrontRow.
To find deals like this, go to http://store.apple.com and look for the red SAVE tag in the right sidebar.

Invalid Device Error when using Labview to comunicate with Jorway 73A

I'm having a problem when trying to get Labview to communicate with the Jorway 73a CAMAC crate controller. Keep in mind while reading this that I'm still fairly new to both the CAMAC system and Labview. I've downloaded the drivers for the Jorway 73a off your site and run into a "Invalid device" error whenever I try to read or write from the CAMAC crate using the read or write VI's. Oddly, the initialize/clear/inhibit VI runs without error. When reading cmjwdll.c I can tell that this error occurs whenever "the device selected is not a JW 73A". Not sure why I'd be getting such an error, and only with the read/write VI's, not on the initialize/clear/inhibt one.
Thank you for your time.

Hi Caleb,
You may want to contact [email protected] for this question. Looking at the driver (http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/398258c61da17663862568ab005fbcbc?OpenDocument) It states that these drivers use 32-bit dll's that only work on 95/NT and are provided by Jorway.
Hope this helps out!

I called this problem into Apple and they solved it for me. The problem is in the downloader associated with iTunes. Skip that step and go to Apple.com and download the new iTunes softwere update (Version 11.1) directly. I did this and installed it successfully. After restarting the computer iTunes recognized my phone and all was well. Then I updated and installed the ios7 update without any problems. No charge. Full cudo's to Apple!
