IPod Nano: Error Message "The USB device has malfunctioned and Windows does not recognise it"

Hi everyone, I just received 2 brand new iPod Nanos for my kids for Christmas, thought I'd be smart and sync them both now before wrapping them so I don't have to be messing around with them on the day. One synced without a problem, then using the same cable, same computer, same USB port, the 2nd one came up with "The USB device has malfunctioned and Windows does not recognise it" I've tried restarting my computer, unplugging and reinserting the USB. Is there anthing else I can try before returning it? Thanking you for any help.

I have solved my problem, I ended up ringing Apple and got an awesome lady who told me to reset it by pressing the sleep button and menu button together for about 10 seconds and once it actually turned on for the first time the computer then recognised it, so it's all good, :-) Thank you lovely lady!

I don't have a wireless printer, and want to print things off of my iPad. I know that I can use the iPad Camera Connection kit to connect USB devices like keyboards and I am wondering if I could do the same with a USB printer.

I don't think you can connect a printer since you won't have the printer drivers. I use FingerPrint from collobos.com to print to my non-AirPrint printers.

I am unable to download photos from three different cameras, Sony, Samsung and Nikon using the lightning USB camera connector. I get a error message saying the the USB device uses too much power.

You may be able to over-come the problem by using a powered hub.

Itouch - USB device not recognized and Itouch now no longer works

I'm now on my 3rd Itouch since December all due to the same problem. All seemed to be going well with my 3rd replacement Itouch. Having loaded most of my cd collection into ITunes the night before I was going on holiday I synced my Itouch. Some sort of automatic download took place I think from Microsoft and suggested my drivers were being updated. Next thing I got message to restore my Itouch to factory settings. I did this and all the problems I had with my previou Itouch's started again.
When I now plug my Itouch into my laptop it says "USB device not recognized" and the Itouch will not switch on. I've done everything including reinstalling Itunes, holding down the power and home key but to no avail. Looks like I'm going to have to send my Itouch back again. I have a suspicion that a Microsoft download is corrupting the drivers. If anyone can help I would be very grateful. I really like my Itouch but the fact it keeps failing leads me to wonder if I should opt for something else.

Try leaving it plugged in and then restart the computer.

USB drive with install image is showing in Startup Manager on a Mac Pro, but wont boot. Showing circle with cross strip, and shut down automatically. USB device are made and work on two different MacBook Pro, but used on Mac Pro. Any help?

OS X installers have always been fairly specific, hardware-wise. I haven't read anything reflecting that situation with the Recovery HD, so it may be that the Recovery HD created for the MacBook Pro does not have the necessary drivers for the Mac Pro. Obviously, nothing definitive here, but a possibility.

Does anyone know how well the Intel Iris Pro installed on new 15" MacBook Pros performs using Photoshop and Lightroom? I have seen some differing opinions out there, and I would rather not shell out the extra cash for the Nvidia if I don't have to. I mostly do photo editing for business and personal use. I have not used the 3D function in Photoshop, but I would like to know that I could.

Flash player on the new mac sarafi can't use keyboard and event listener

flash player on the new mac sarafi can't use keyboard and event listener
cn:英文有些差不好意思，附上中文说明：在flash player web 开发时，我在最新版本的sarafi上，目前出现不能响应键盘事件bug,为了验证是不是我本地问题，我也用在多款别的网页游戏上进行测试，全有这个bug，另外，有时还有那个fp弹出本地缓存提示设置窗口也点不了“允许或拒绝“那些按钮

Now after 5 weeks, you have always not resolved this very important and urgent issue. It seems that Adobe has realy abandonned the actionscript / flash player projects. Why not simply discontinue flash player on desktops too ? Or even better remove or block "automaticaly" all flash players with the final update. That could create a serious issue on the Internet for few weeks but at least that will be honorable end like a Samurai's Seppuku...

IPod not recognized. says"USB device not recognized and has malfunctioned

I just bought an iPod nano from one of my friends and i got the usb cord off of ebay. when i connect my ipod to my computer. it says usb device not recognized. i've installed software and everything. i've downloaded iTunes and all the ipod software i can find including the updater and other downloads from apple. PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

After switching to a Nano, my Dell pocket DJ is having the same problem you are describing. I can't tell what the fix is but I plan on purchasing a new USB as I suspect that may be the problem.

USB device not recognized, and more!

This morning when I tried to sync m y Z22, I got "USB DEVICE NOT RECOGNIZED". Connected the cable to every one of my USB ports, tried to sync each time but got the same message.
I shut down the PC, unplugged it, waited a few minutes, reconnected it, rebooted, and tried to sync again. Still got "USB DEVICE NOT RECOGNIZED".
Checked Palm Support, was advised to upgrade to the current version of the software (I was using V4-something). Downloaded and installed the upgrade. I got an error at the end of the installation that (what I assume was my old software) had been moved to Palm OS Incompatible Apps.
I tried to sync again, same problem. Opened the (new) software & half my data is gone.
So, I have a few problems:
1 - How do I fix this &^#$!!! USB error? and,
2 - How do I roll-back the software to my previous version to access all my data? In Add/Remove Programs, with Updates checked, the new software is the only one there. (Because I couldn't sync, at least the data on my Z22 is still intact.)
Someone PLEASE help, my whole LIFE is in this thing!!!
Thanks in advance,

How can I best control a non NI USB device using LabVIEW?

One of our radio products has a USB port for local (test) control. When I connect the radio to a USB port on my computer the NI Measurement and Automation Explorer does not recognize the device. Nor does it recognize the device when I attempt to "add new device".
Within LabVIEW I am unable to assign an appropriate VISA resource name that does not cause an error when attempting to use the "VISA USB Control Out" or "VISA USB Control In" functions. The help page for wiring up these functions is unclear, particularly for the "request" and "request type" variables.
Would it be best to pursue this current method or purchase some type of serial (com port) to USB converter hardware to communicate with my USB radio?
Regards
Roger

Sorry for the hijack, but this is a related question... I have an LV application that works using COM1 on the PC. Customer wants me to change to a USB-to-RS485 converter. I installed the Windows driver for the converter, then plugged the converter into USB port on the PC. Windows and MAX both see the new port. What I'm not sure of is the best way to have the LV app find the converter. This application will be used on a variety of PCs so the COM port will be likely to change from PC to PC. Or even on the same PC, sometimes another USB device might get plugged in before the converter.
So the question is this: The converter will always have the same vendor ID. Is there a way for LabVIEW to look at the USB devices and pick the one with the correct ID ? Or maybe this is overkill... the Windows driver makes the converter look like a serial port (COM4 on my PC). The original app that worked with com1 used the VISA Configure Serial function with ASRL1:INSTR.
I can modify the LV app to force the user to pick from the available COM ports, but would prefer to make this happen automatically.
Any suggestions ?

Android / USB devices keep connecting and disconnecting on R7

My daughter has an R7, and she is having a weird problem with the USB ports on it.No android device can stay connected. As soon as you plug it, it makes the connect sound then the disconnect sound and keeps cycling between connecting and disconnecting. It is not related to the device as I have tried two different phones and one tablet all with different cables, all work fine on other computers. And I tried on the three available USB ports of the laptop, all behave the same. Searching online I found a lot of people with similar issues mostly unresolved. I did disable the USB suspend option in the power options without any results, as well as uninstall all USB hub so they would be reinstalled at boot time, and installed all optional windows updates. She is also experiencing another issue on her USB ports, we have a Samsung slim external DVD player that uses a Y USB cable for data and power that also works fine on any other machine. On her R7, when playing a Video, the video keeps making blocks at regular intervals like something is preventing the full data stream. Wondering if this is related. Apart from that, USB mouse, USB keys or external USB drives appear to work fine. Anyone with a similar issue and a definitive fix?

Thanks, but I seem to have found a solution to both issues. 1) Regarding the android devices that kept disconnecting and reconnecting, after readiong this threadhttps://support.microsoft.com/en-us/kb/2900614 I checked what registry keys were present on my wife's surface pro3 for
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_XXXX&PID_XXXX\YYYY\Device Parameters and found that there was three DWORD values in there that were not present on the R7SelectiveSuspendEnabled
EnhancedPowerManagementEnabled
DeviceSelectiveSuspended So I added these 3 DWORD and set them all to zero, and the issue is gone. You may not need the three of them, but I have not tested them one at a time yet. 2) For the External DVD blocky playback, it turned out to be quite trivial. Someone had enabled hardware acceleration in the VLC player settings. I reset all the VLC settings, and it worked fine from there. Hope this can help others
