USB comm to a 9 Pin device
I have a device that we sell and a LV application (built using V5.1) that is a 9pin serial and receives simple ascii commands and ships back ascii data. With the demise of the 9 pin, many of our users have gone to a USB to 9 Pin adapter and all works ok. Lately, we have been getting intermittent results on newer operating systems. Basically, sometimes the communications occurs and sometimes it does not, even on the same PC/device. I am looking for suggestions of what might be going on and possible solutions. Thanks is advance for any help.
The NI USB-232 boxes support both DTE and DCE operation modes in addition to an "Auto232" mode that simplifies cabling (null-modem? straight-through? doesn't matter!). Also the USB-232 has indicators for transmit, receive, error, and signal validity which aides device communication development. In addition NI's serial products support 5,6,7,8 data bits, NOEMS parity, and RS-232 baud rates up to 230.4k with a driver architecture designed from the ground-up to support the higher serial bandwidth.
These features are all in addition to the world class support that differentiates National Instruments from other vendors.

Usb will only work for powered devices
I am having an issue to where my USB ports will only work for devices that have power supplied to them, ie an external hard drive that has a power adapter and not for devices that do not have power supplied to them. I was seeing if anyone could help me resolve this issue?
I have a Macbook Pro 15 inch Late 2011 model w/ the 2.2 Ghz i7 Processor.Eustace Mendis wrote:
This is simply a case of the USB ports not being able to provide enough power. I do not know if there is a way to change this.
This is highly unlikely, the USB specification (to which Apple adhere) requires a constant 1 amp at 5 volts, a peak of 2 amps for a brief period is available. All reputable manufacturers adhere to this spec, it is more likely a fault condition.
To the OP, reset the Pram http://support.apple.com/kb/ht1379
and reset the SMC http://support.apple.com/kb/HT3964
Reboot the machine and try again.
If this brings no relief you should follow Oglethorpes advice and take it to Apple for repair. -
My USB ports will not recognize any devices, iPhone or external drives. Keyboard and printer work, any suggestions?
I'd start by looking in system profiler.
the blue Apple icon > About this Mac > More info...
goto the hardware section. Scroll down and click on USB
See what happens when you have the device plugged in & not plugged in.
Move keyboard & mouse around to verify that ports work. Plug device in a port that worked with keyboar or mouse. Keyboard usb ports are rather low power.
Perhaps device is taking too much power. Are devices power or unpowered? Try connecting devices to a usb hub.

Macbook Pro 15" USB PORT DOESN'T RECOGNIZE ANY DEVICE.
I got my macbook pro 15" for about 1 year and 2 weeks ago, when I turned on my macbook and put my mouse ( Death Adder) into the USB PORT, my macbook DOESN'T RECOGNIZE IT. There are 2 usb ports on my macbook, I tried both port and there was only one port work correctly, the other one didn't work at all, I also tried to put my memory stick, external hard drive, vodafone 3g usb, ipod,....into that USB PORT but non of them worked. Is there any one here have the same problem???? Can you guy help me please. I stay quite far away from Apple Store so it is hard to bring it to repair. I tried to reset SMC, Update Software,...but still not work...HELP ME PLEASE...
I can't fault your troubleshooting. Sounds like a bad port.
Home remedies are limited. You can grab a magnifier and shine a flashlight in there. If you see any foreign material, use a toothpick or other non-conductive tool to extract it. If you can, give it a good blast of (dry, canned) compressed air to blow any particles loose.
Sometimes you can trick a flaky USB port into working at least intermittently by plugging in an extension cable or right-angle connector. Play with a device that lights up so it's easy to see whether it's working.
Take a hard look inside the connectors at the end of your Death Adder and other frequently-used devices. If you see any corrosion or bent pins, that's what damaged your USB port.
If the port requires physical repair, it's best to use Apple or an authorized dealer because if they make things worse while trying to fix it, they have to make it right. Joe's Appliance isn't similarly accountable.
If you need more USB ports, ExpressCard to USB adapters are dirt cheap.
Good luck. -
AT200-101 USB OTG strange behaviour with all devices
Hey,
I've got an AT200-101 with an updated ICS 4.0 OS and I can't get the USB-hostmode to work. After a lot of reading about the fine difference between the regualar (type B) USB connector and type A (known as OTG) I finally have got the right adapter (it has a recangular shape and the ID-pin is grounded).
Now each time I plug in a device (usb massstorage device, 3G modem) nothing happens except the AT200 suddenly shows *charging* even though it's not connected to the charger nor is the connected device externaly powered.
I tried these external USB devices with an other ICS tablet (Zenithink) and they work fine.
Andybody any clues?If you have an active USB-Hub (with an own power supply) at hand, you can try to put that in between the device and the AT200 + USB-OTG Adapter.
The AT200 seems to allow just a very low consumption of bus power. -
Front USB doesn't work with some devices
Hi,
I have 2 front USB ports and have wired everything correctly (not using the 10th pin). I tried my digital camera and the maxtor USB hard drive and they both work. When I try plugging the Adaptec VideOh! USB capturing device, it doesn't seem to work right. It is detected and the drivers for it installed correctly, but I can't capture any video. When I unplugged it and plugged it to any of the 4 ports on the back, it works fine. The D-bracket ports also worked ok with the device. I wired the 2 front usb ports the same way as the d-bracket (they both have the same color wirings). The front ports seemed to work ok with the other devices I mentioned, just not the Adaptec Videoh! USB device. There is a JUSB1 and a JUSB2 on the motherboard. Are both the same? I have JUSB1 for the D-bracket and JUSB2 for the front usb ports. Both are wired the same. I just wonder why the Adaptec device can work with the D-bracket and not the front USB ports even when they are connected the same way. Any suggestions?At the cable end that plugs into the motherboard snip the jumpers between pins 7-9 and 8-10. See Wonkanoby's signature for a link to diagrams.

Right USB Port stops working after disconnecting device since 10.9.2
Hi,
Since updating to 10.9.2 the right USB port on my MBA stops working after diconnecting a device (tested: external hard drive, USB flash drive, USB HSPA Modem). The only way to get the port recognizing the device on that port is to do a restart. If the device is connected from starting the MBA it works fine, if I then eject the drive and reinsert it or a different USB device the device doesn't get recognized. The devices do get power, my WD passport ultra spins up just fine, the USB HSPA modem also indicates it's working (with signal) but nothing shows up in finder or diskutility. If the modem is connected from start (and thus working) and then disconnect from the internet but not remove the drive I can reconnect to the internet. The problem only occurs after disconnecting the device. The port becomes inactive. The left USB port works as expected.

Nothing out of the ordinairy. Thanks for any helpIt's an Apple Pro keyboard and mouse, the dongle is
plugged into the Mac and not the keyboard. The same
set-up is, and has been working on all our other
Macs.
The sleep issue sounds interesting- hum, maybe...
Is your keyboard plugged into one of the USB connections on an Apple monitor? If so, you may want to change that connection to one that is on the G5 itself. My monitor came with a warning note indicating that problems will likely occur if the keyboard is connected to the monitor.
I also had a problem with the automatic sleep function. After much trouble-shooting and a logic board replacement, it was concluded that coming out of the automatic sleep function with any USB device active would freeze the entire USB bus. After disabling automatic sleep in system preferences, I've had no freezing problems. My machine works fine with the manual sleep function in the Apple Menu.

I recently purchased my iPod touch with no issues. After updating to iOS 8.1.1 I found that my iPod would no longer appear in the latest version of iTunes and when I searched for Apple Mobile Device usb driver in the device manager, it was nowhere to be found. I've already uninstalled and re-installed ALL components of iTunes and read every single help article. I've tried everything. What went wrong?
See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:
iOS: Device not recognized in iTunes for Windows
paying special attention to item #5
- New cable and different USB port
- Run this and see if the results help with determine the cause

Ipad 2 dock - does it with anything other 30 pin devices?
Hello
I have an apple ipad dock (30 pin) which I used for an ipad2. Can this charge other 30 pin apple devices? I have tried an old ipod nano but it doesn't fit. I wondered about older models of iphone or other ipod models.
many thanks
SusieThanks Phil
I have tried it again with the Nano and on a closer look it's appears that the contours of the device prevent it from sitting/ connecting properly in the dock. The dock is shaped so that it rest against a back piece, just behind the connector, so unless the device shaped in the same way as the ipad then it's unlikely to connect. I should have realised this before I posted. Thanks for taking the time to reply.

USB to 232 how to get device instance id with labview
I'm using chip CP2102(UART to USB) to communicate my board with PC.
On PC, i installed the USB to UART Bridge Virtual COM Port driver so it shows a virtual COM Port on the PC.
In the device manager of the PC, it can read the Device Instance ID(USB\VID_10C4&PIC_EA60\0001) of the usb port as well as the virtual COM port number(COM11).
But in labview, i can only get the COM port number when i try to find the resource. Even if in MAX, i can only get the COM port number.
I need to use one PC to control several boards, so i need to recongnize the boards with the Device Instance ID.
Is there some way to get the Device Instance ID of the virtual COM port in my labview program?
Thanks a lot.
JasonWe did similar sort of thing with FT232 chip based devices.
But we used our PC Port as the basis of detecting the devices rather than the device itself.
FTDI has drivers to address devices based on PC USB port number.
This could be of bit help as well.
http://www.ftdichip.com/Support/Documents/ProgramGuides/D2XX_Programmer's_Guide(FT_000071).pdf
The LabVIEW Drivers are available on their website.
You might want to do something similar if you don't want to go ahead with FTDI chip. -

USB Ports not working with specific devices
So this one has me scratching my head. My USB ports on the back of my iMac are working except for a few devices. 1 being a logitech USB receiver, and 1 being a usb mp3 player. When I plug the received into the iMac the keyboard won't work, but when I plug my USB hub into the same USB port and the receiver into the hub it works fine. The mp3 player isn't working in any usb/hub (so that's a mook point).
Here's what I've tried to resolve this issue:
1. Reset iMac
2. Reset PRAM
3. Try every usb port on the back of the iMac
None of these have fixed my issue. Plugging it into the hub isn't a huge deal, but I'd like the option to use my USB ports as I wish without having to deal with this. Anyone have advice on a solution?It is not a matter of using your USB ports as you wish, it is a matter of what you are plugging into them and the power demands that what you plug into them makes on the system.
Not all USB ports or devices are created equal. How many ports are you using? What exactly are you plugging into the ports? What is the power demand of each item that you are plugging into each port? Are any of the USB devices self powered from their own separate power supply? Are all of the devices dependent upon the iMac for power?
It sounds to me that you have too many high power devices demanding more power through the ports than the iMac can accommodate. Is the USB hub self powered? If so, that is probably why it resolves your issue with the Logitech Unified receiver. There is very little info on this device on the Logitech website, so I could not ascertain its power demands.
