Envy Touchsmart 15-j105sa Continuous USB Device Dropout and Reconnect

New Envy Touchsmart 15-j105sa running an up to date version of Windows 8.1.  All HP driver and Windows updates completed prior to installing software and other USB devices except for USB WiFi adaptor and software.
USB 2.0 HDD keeps disconnecting from the port and then re-connecting.  This happens continuously about once every 30sec.  It re-connects after about 10sec and then disconnects again after about 30sec.  When connected everything seems to be working fine.  Access to the HDD is OK, it shows normally in Device Manager and Safe Disconnect.
I have uninstalled the USB drivers and restarted.  The problem persists.  I have powered the USB HDD externally.  The problem persists.  I have tried connecting to 3 of the 4 USB ports.  The problem persists.  The USB 2.0 HDD works normally on other Laptops.  When data is being transferred the dropout does not occur.  It appears to be associated with idle time on the USB HDD.
I don't get the problem when I attach a USB 3.0 HDD.  It stays connected with no dropout.  Flash drives don't have the problem.
I also have a similar issue connecting a USB Alfa WiFi Adaptor.
UPDATE:  The problem is related to an External Combo Drive.  2.5" Sata to USB /eSata HDD External Enclosure.  As long as the HDD is being accessed then there is no dropout.  As soon as the disc becomes idle I get a cycle of disconnects and reconnects as described above.  I would like to understand the cause of this issue because it will help solve the massive connect/disconnect hunting that I get with my external USB wifi adaptor.  Once the Alfa Wifi adaptor gets happy with its connection the hunting stops and it behaves normally.

Are you using the charging USB 3.0 ports or the standard USB 3.0 port to connect the device?
Charging ports have a + next to them. It really should not make a difference, but it might with your keyboard since it does require more power then, perhaps a mouse.

  • Continuous USB Device Removal Messages on certain Flash Sticks since 10.5.2

    I have run into a problem with both my MacBook Air and Mac Pro since running 10.5.2, and this was not fixed in 10.5.3:
    Most Flashsticks appear to be continuously removed and replugged over 5 sec intervals. I continuously get the "Device Removal Warning." These worked before, and do not have the problem running under BootCamp on the same machine, or being assigned to VMWare. An example is an Emprex 4GB stick, which was not cheap, when bought. They also do not have issues on Dells, or Macs running tiger!
    These are plugged directly into the system, no hubs or cables in between.
    There are other brands that do not have the issue.
    Has anybody run into this? This is very annoying.

    I'm seeing that issue with an Adata 8GB stick (www.adata.com.tw).
    That same stick works fine on my MacMini (ppc), Dell 700m, and Lenovo T60p.
    In all cases, I'm always connecting the stick directly to the systems.
    The failure happens at various times after insertion. Sometimes Finder doesn't event display the contents, sometimes I'm able to copy 20MB before the copy hangs. In all cases (dozen times) on the MacBook Air, it never worked reliably.
    The MacBook Air USB port is not (completely?) busted, as it works fine with my Maxtor OneTouch USB2.0 external disk.
    Applications -> Console shows the following messages, starting from device insertion to "Device removal" error message:

  • PTCL EVO USB Device Installation and Configuration (EVDO CARD)

    *PTCL EVO Installation on MAC Book PRO , Mac Book Air EVO*
    Problem:
    USB not getting detected on MAC book pro and Mac book Air.
    Resolution:
    *DO not Insert the EVO CARD until you perform the below:*
    *Getting the driver:*
    *Option 1 :*
    http://ptcl.com.pk/contentb.php?NID=327#drivers
    Select the device you have and download MAC driver from the download section on the page.
    *Driver Option 2:*
    ON windows os insert the EVO device detect the USB disk with drivers one of the driver is for MAC (dmg file) copy it on a simple Flash disk.
    *Installation on MAC:*
    Double click the downloaded driver (Option 1)
    run the setup.
    or
    on your MAC Insert the Flash Disc on which you copied the driver (Option 2) it will detect a media storage and then run the driver from there. Once you have the driver installed you will see an EVDO Icon in the menu.
    *NOW insert the EVDO USB in MAC it will be detected as a modem / network device.*
    *TRICKY PART:*
    EVO software does not work on MAC so you need to configure a manual connection.
    Go to network settings from the top panel under WIFI click advance settings. A new menu opens up you will see 3 or 4 new devices. you need to configure the EVDO Card Terminal only thats the first in the list.
    *Do not configure any other device.*
    *Config Settings:*
    phone number: #777
    User: [email protected]
    Password: ptcl
    *Do not change any other settings.*
    Click connect and within seconds it will connect.
    It works fast and reliable for all wimax services location is very important it is dependent on the signal strength. EVO is the best choice for people on the go as it works across Pakistan in 350 cities. no other service can match this.
    Please note I am not from PTCL or any affiliation with them. Check my website for more details…

    Hey Mark
       You didn't happen to change the IOMMU setting in the UEFI did you?  I have just got a M5A97 EVO and been having problems.
    This UEFI interface finds the usb devices fine but the kernel will not.  I found that if I flash the bios it reset things and appears to
    just compare the flash if it is the same.  Afterwards the usb works. However I still trying to narrow it down myself.  I've tested with
    0402 0810 & 0813 just released. All do the same thing with regards to usb 2.0.
    Jonathan
    EDIT:
    After testing it appears to be connected to the linux nvidia blob & IOMMU settings conflicting.

  • How do I play dvds on hp envy touchsmart 15 notebook with an external player and Windows 8.1.

    I have a HP Envy Touchsmart 15 NOtebook PC. I bought an external HP DVD player model dvd600s-H01 5 but I cannot play DVDs.

    Hi @pattyathome 
    Welcome to the HP Support Forums!
    I understand that you are having trouble with an external  dvd player attached to your notebook.
    What is the full product number for your notebook? Please read the following if you need help in finding that.
    How Do I Find My Model Number or Product Number?
    Does your notebook already have a built in dvd drive?
    Did you install the drivers and software that came with the external dvd player? If there was originally no DVD player in your notebook, it is likely that there is no dvd player application loaded.
    So in that event I would recommend installing from the software disk with the DVD drive.

  • Please help me, USB Devices instantly disconnect/reconnect when using keyboard

    I own a Lenovo 3000 C200. IIf I start typing while I have any USB device plugged in (USB mouse, Removable HDD, etc), the USB device instantly disconnects and reconnects again. As long as I don't touch my keyboard, the USB device will work fine. I have noticed that this does not happen when I press the the other keys like the Lenovo care button, volume increase / decrease key, etc. and doesn't happen when I use the touchpad. I have not dropped or damaged my machine in any way.
    At the beginning, thinking it might be a windows problem, I had re-installed windows (XP) with no drivers installed and the problem persisted. I installed the latest update available for the BIOS still with no luck. I have checked the BIOS, however there is nothing related in anyway that can be configured.
    Just now I have noticed that the problem begins, as soon as I turn on the machine. Hardware problem perhapsI
    Please help me.

    This happened to me exactly the same, you must updated the latest bios version 2.06.
    Now go to the Lenovo website to download the oldest version 1.02  and the 1.08, first flash the 1.02 then flash again using the 1.08 that it, don't use the 2.06 which is the porblem source file for some 3000 notebooks.

  • How to increase the Speed of USB Devices (6501 and 6009)?

    Hy guys!
    My question is:
    In datasheets of the USB devices, the only reference about the speed of
    these boards is the Bus Interface speed (12Mbit/s). But in my
    application (i'm trying to use delphi to control the device), each
    instruction, doesn't matter if is a write or a read function, is taking
    1ms to execute. Could i increase this speed?? What could be wrong?
    OBS: I updated the Ni-DaqmxBase 1.4 to the new NI-DaqMx 7.5, and notting has changed.
    Functions used:
    istatus := DAQmxWriteDigitalU32(TaskEscrever, 1, 0, -1, DAQmx_Val_GroupByChannel, @writedata,nil, nil);
    istatus := DAQmxReadDigitalU32(taskLer, -1, 10, DAQmx_Val_GroupByChannel, @readdata[j], 1,nil, nil);

    Hello,
    The two usb DAQ from NI are full speed interface (as you said 12M/s bus speed). The full speed interface has a frame size of 1ms, the root hub transmits a packet every 1.0 ms and this is the minimum time that you can read/write from/to usb device, normally because of the windows scheduling, 1ms is very tight, windows may miss it in some occasions, some usb device designers would prefer to use something between 2ms - 10ms polling period, which means some devices may even react to commands within 2ms - 10ms. But it looks like the two NI usb DAQ use the 1ms polling period and that is the shortest time you can get in software paced mode. If you need very fast digital update rate, you may need to look at PWM output, it generates digital pulses at very fast rate as the link given below, the iUSBDAQ - U120816 can generate PWM pulse from 3kHZ - 333kHZ.
    NI USB DAQ maybe good, but it wouldn't hurt to look at some other company's product too. the below link of usb daq gives the best price/performance ratio, LabVIEW vis are very easy to use and you avoid the pre-configuration in a separate application for DAQs which sometimes may be big deal if your customers are not engineer or scientist, but regular computer users. You are welcome to compare.

  • Mountain lion USB devices issues and Cam

    Hey Guys,
    Since updated to ML, started having an issues with many USB devices, (Apple wire Keyboard, Razer Deathadder mouse, iPhone, NI Maschine, Guitar Rig Mobile), basically everything that is connected over USB bus. As well as Web cam, not sure how its connected internally but looks like over USB as well. Mentioned above devices sporadically getting hanged and becoming not available and I have to reboot the whole iMac (this is insane!!!). My is iMac 27-inch, Mid 2010 (3.2 x2 cores, 8GB of RAM). In general, system super slow, Terminal is lagging when openning (its simple Bash, changed to zsh by default, much better), didn't had such issues on Lion nor on Snow Leo.
    Please help! what can be done to fix this? Should I roll back to Lion? When will be an update for those type of lags? this is epic fail.
    Best regards,

    Another iTunes 11 crash.  Something as simple as downloading one new app to the iPod Touch 5.
    Memory seems to really climb when searching iTunes store.

  • USB devices disapear and only reappear after a full power down

    Hi All
    Has anyone seen this before, The USB devices (Mouse/Kboard/ilok) started to be flaky and then disappeared. After a soft restart the Mouse and keyboard came back but not the Ilok. After a hard reset eg pulling power for 30sec everything has come back. Is this a sign of things to come, power supply issues etc?
    Thank you
    Mal

    In some cases, the keyboard plus mouse is right at the edge of acceptable power draw, and adding anything to the second keyboard outlet causes it to malfunction or over-power and drop out.
    The Mac Pro has separate power budgets for the front ports in total and the back ports in total, so one approach might be to plug in the other stuff on the other side.

  • Why is my USB mouse disconnecting and reconnecting?

    Our USB mouse has been disconnecting and reconnecting intermittently. There doesn't seem to be any rhyme or reason for it. We're using a Logitech Optical Mouse. It doesn't seem to matter which USB port it is plugged into. Occasionally when it becomes unconnected and doesn't reconnect, unplugging and plugging it back in will "fix" it. I've been using HardwareGrowler to keep track of this. This was occurring before we updated to 10.7. I may be imagining this but it does seem to occur more when it is running hot.
    Thanks

    I have yet to try a different USB mouse to see if it is the mouse itself. I did plug in my iPod and there seems to be no problem with connection there. The mouse will disconnect regardless of tempature and it seems to disconnect more during heavy usage (gaming).

    I'm having a devil of a time trying to get access again to a set of devices which worked fine under Vista-32 and backward..
    Recent self-repaired problem, The laptop refused to accept a Garmin eTrex GPS via any other USB port except port 1 (the top-left port).. Attempts to attach it via ports 2 or 3, resulted in failure to read device, and Windows Device Manager reported the GPS asn an unknown device.  The fix to get it to accept the device on these ports, required uninstalling the driver to those two ports (plugging the device into either of those ports, when seen by Device manager, uninstall the device, unplug it, the plug it back in again.)  result now, all 3 ports will now accept the gps.
    Now, an old device failure..  I have 3 different Prolific USB to Serial (rs-232C) adaptor cords, for connecting to older serial devicees. (older GPS's, external older computers, robotics projects, etc.)  as of yet, the above remove/replace method will not allow connection of these cables (yes, using the supplied drivers, and a few generic found online from Prolific themselves) and, likewise refuse to access the devices connected to them.
    There is one other device, which uses another form of USB to serial (FTDI Chip, device is the Arduino microcontroller, which uses the FTDI D2xx chip to connect via USB) I'm surprised, is actualy in the installed Windows-7 driver library, as well as a Microchip PIC18C745 (Vellaman P8055 project board) (also native device under Windows-7)
    I've tried to find a reliable Prolific driver, but as of yet, these devices (Including one used in Microsoft's labeled version of the Pharos GPS500 dongle, which is sold with Microsoft Streets & Trips 2009 (The driver for this one, on other computers has caused system crashes.. Even under Vista & XP)
    Is this a problem with the laptop itself, or Windows-7 that I'm fighting?

  • USB device plug and the MagSafe port

    Hello,
    I accidentally got an USB plug too close to the MagSafe port and the magnet pulled it in. It of course didn't fit, but I was wondering if the magnet could have caused any type of serious damage that might show up in the long term. The device in question is my Microsoft Natural Wireless Mouse. Shortly after the incident a dialog box popped up and told me my wireless device signal had been compromised (I don't remember the exact wording), but I restarted and everything is fine now.
    Could the MagSafe magnet cause any kind of electro-static that might be harmful?
    Just wondering, and thanks.

    If it did, I'm sure Apple wouldn't make it.

  • 'USB device malfunctioned and Windows does not recognise it'

    This started happening today. So I went on the Apple website to try and find a solution. I looked on all the troubleshooting advice it gave, including restarting my iPod, reinstalling iTunes, restarting my computer, I've tried everything to try and get it to connect to my computer again, but unfortunately nothing is working. Then I went to the last resort of restoring my iPod, got it into disk mode, but my computer still wouldn't recognise it so, I couldn't even restore it. My iPod is basically new, I only got it for Christmas 2010 and I'm always careful with it. I don't know if it might be something to do with the drivers needed to recognise my iPod or if it's the actual iPod, but I have no idea how to go about fixing it. Please help me!

    yea
            In some cases you might have to change the Usb cable, change the usb port,  check if the computer drivers and properly installed, restart the computer and relaunch itunes again to restore. i dont know if you also used this but click on this link and you might see you solution      http://support.apple.com/kb/ts1567
