Driver in Windows 7 USB-serial adapter problem

• Timeout of read with USB-serial adapter

  Hello world

  Sorry to post this kind of question again, but I spent 2 days to navigate on this forum, the forum of The Mathworks, and several web pages, I still cannot find the thing that will solve my problem

  I'm trying to control an Agilent 34970 A (with 40 channels 34908 A module) to read values of temperature thermocouples. I use a laptop (win7/64) and an adapter USB-to-serial (MCT U232-P9, who uses the Philips P87C52X2BA, not the FTDI chipset in case it makes a difference) and I installed the driver for this card. The adapter is recognized by Windows and appears as COM4.

  I put the COM port settings in Windows as they are on the unit (9600 baud, parity: none, 8 data bits, flow control: Xon/Xoff; the stop bits are not specified on the device).

  And... TADAAA... it does not work!

  I tried to use NI MAX (version 5.5), LabView (2013/32-bit version) and MatLab (R2012b) to send the * IDN? command and read the response. The part 'writing' is fine (at least it does not generate an error, but I don't know if the command reaches the instrument), but there is no response from the unit. If I try to read the COM port, I get the 1073807339 error (time-out before the operation ended). I tried to see if there any bytes that will be read at the port, but there is no...

  In LabView, I put the Xon and Xoff characters to those specified in the manual of Agilent (0x11 for Xon and Xoff 0x13), but there are a few other settings that I am not so sure: "Activate termination Char" (should be on or off? Tried both - no change) and the tank itself ending (I left it to the default '\n').

  I know this isn't really a problem NOR / Labview, but given that so many people in this community seem to have experienced this problem, I would be very grateful if someone can help solve me this problem!

  Thanks in advance

• USB serial adapter works once for each reboot...

  I have a serial adapter USB to connect to the CONSOLE of the switch/router port and I use 'screen' inside the Terminal to connect. Recently, I found that the "screen /dev/cu.usbserial 9600" works only once for each restart of the system. Steps to reproduce:

  1. the output of "ls/dev / * usb *" shows the right device.

  2. connect to the console of the machine with 'screen /dev/cu.usbserial 9600 '.

  3. press on "Ctrl + A, Ctrl + K" to exit the screen

  4. (optional) disconnect/reconnect the usb to adapter series laptop OR disconnect/reconnect the cable to the device console target.

  5. the output of "ls/dev / * usb *" shows again the device.

  6. try to connect to the console with "screen /dev/cu.usbserial 9600", the process of the screen will hang. Once what is happening, the screen process cannot be killed by 'sudo kill-9' and only be solved by turning off the power full. BTW, the laptop will hang also when the start/stop, until I continue to press on the button / stop...

  7. When hanging them screen, the output of "ls/dev / * usb *" would show nothing.

  Once the notebook starts up again, I can connect with the same command screen and the same scenario for step 2-3 above...

  I have Mac OS 10.11.3 and adapter Micro Innovations brand (prolific chip). I downloaded and installed/re-installed driver from the prolific site and no difference...

  Any idea?

  Still questions... help!

• USB Bluetooth adapter problems

  Hello

  I recently got a new Toshiba Tecra S1 (PM725) and an adapter Bluetooth usb (with More4you software).

  But I can't make it work with my nokia 6310i

  I installed new battery BT (Bluetooth Stack for Windows by Toshiba (3.10.00).

  Analysis of my nokia BT Manager, but when I want to connect to it, it immediately disconnects (after that I supported on accept connection on my nokia pairing) and the BT Manager gives the error: a not to connect to the following service: Dial-up networking. Connection request failed.

  I only installed the BT stack (from dir... BT package /US/) because when I run the installer from the main dir, it does not recognize my BT adapter. He keeps asking to put the int bt adapter.

  I had once it works, but with the next time you start it failed once again.

  Could you please help me?

  Hello

  Therefore, it is very difficult to say what the problem is. In my opinion, it is very important that
  -Adapter USB Bluetooth is installed correctly and working properly
  -Nokia must be added and installed as a new modem
  (The Nokia modem driver must be installed)

  It is not easy to help you because More4you and all settings and options there are unknown for me.

  I think before you start doing anything check there at - it problems with the USB adapter. Next step is the installation of the Nokia modem driver. I'm sure you have some CD or you can download it from the manufacturer's website.

  Please be careful with COM ports (you can use the standard port). In my case the standard port was COM 40. The same port, you must choose to install the modem driver.

  Try again. I'm sure that there is a problem with the settings. Check all out them again.

  If you discover that a problem was it please write again.

  Good luck

• Belkin F5U409 USB to Serial driver for Windows 7

  I have a Belkin F5U409 USB serial adapter. I just spent 3 hours trying to find a driver that works with windows 7 and have come to nothing. does anyone know how this device works on Windows 7? Thank you

  the compatibility report created by windows says that this device should work with windows 7, however, this is not the case.

  I tried to download many different drivers and none of them does not seem to work. I also tried letting Windows Update to find the driver and has as well. Thank you for your help

  If your try Windows 7 or Vista 64-bit, you will find Belkin isn't 64-bit drivers. However, Belkin do not have drivers anyway. You can order this blog post on how to make it work under 64-bit Windows: http://www.clearchain.com/blog/posts/how-to-use-a-belkin-f5u409f5u409-cu-usb-to-pda-serial-converter-in-visawindows-7-64bit-mac-osx-10

• Ativa usb to serial adapter won't install can't find drivers online this work. __

  Any experience with this issue?  Website of the Activa doesn't have the correct driver.

  It is a plug n play device. These devices require no driver. I suggest you to check if you are able to use this device on another computer and after return of the State.

  USB plug-and-play may be, but all devices always needs to have a driver.  No version of Windows comes with drivers for USB serial cards.

  hellofariday - please proceed as follows:
  (1) open Device Manager
  (2) right click on the USB serial adapter
  (3) select Properties
  4) click on the Details tab
  (5) look at the hardware ID

  Then do a search online for any value USB\VID & PID you see there.  You can leave the part REV.

  For example, if you see USB\VID_0409 & PID_005A & REV_0100, you would search online for USB\VID_0409 & PID_005A.  You may be able to find the drivers for a similar device that works with yours.

  Good luck

• HP Deskjet 970Cxi: HP printers - install another driver in Windows 7 to print USB connection cable - PROBLEM

  Hi - I have a HP Elitebook6930P running Windows 7 Ultimate x 64 and a printer HP Deskjet 970Cxi with a USB connection.

  I try to get printing to work.

  There is a 970Cxi pilot in the laptop, but it won't work.

• Aspire driver V3 - 772 G Windows 8.1 USB 3.0 problem

  Hi all

  I bought my V3 - 772G 1 months ago about.

  Yesterday everything worked well and today, I noticed that none of the 4 USB ports were working (laptop was suspended since yesterday)

  No USB not connected, nothing. Key/mouse USB/hard drives /... does not work.

  I noticed that in Device Manager, I had problems with the ' USB 3.0 eXtensible Host Controller Driver "that the driver was not loaded. I've seen people online saying to uninstall and restart the computer. That and once again no operation USB, Device Manager, the device with problems was now "Compliant Host Controller xHCI USB".

  I tried WITHOUT success to the following:

  -Downloaded ' USB 3.0 eXtensible Host Controller Driver "Intel has failed (available only for W7) - Web site

  -Restart windows full - same

  -Disconnecting the battery and power for a few minutes, restarted - even

  -Remove all USB devices (hubs and so forth), restarted - even

  -Uninstalled all updates of 2 days before (to the point that I know that it worked) - pilot months before change - same result dates

  -Tried to search the BIOS to disable USB3.0 and put 2.0 - not found

  -Tried to get back to another restore - point na not work, complained that the disc is maybe damaged

  -Widnows run chkdsk/r several times - no error found - nothing resolved

  -Run chkdsk/r - stuck at 16%, but I guess that needs all night (TODO) - solved anything

  -Tried to do a repair without losing files (using recovery partitions) - always guess how

  Any idea or any help? They just stop working. I plug laptop already with windows 8.1 and they worked for 1 month

  Thank you

  -UPDATE1-

  I used the command-line (via recovery windows at startup) and copied all the files from backup drive (I assume) X:\Windows\System32\Drivers\usb* on the local drive C:\Windows\System32\Drivers

  Rebooted - still nothing

  [Solved]

  Here's what you can try:

  (1) ensure that the ntbtlog.txt file located in C:\Windows it is removed (to clean the logs)

  (2) to activate the startup log check which driver loading fails:

  Option A:

  (1) open administrator command prompt

  (2) write "bcdedit/set {default} bootmenupolicy legacy" to allow the start of legacy with F8 (don't forget to change the settings after this guide)

  (3) reboot and press F8

  (4) select this option to start with active log

  Option B:

  1) press "WIN + R" and write "msconfig".

  (2) in the Startup tab, select the option "Startup journal."

  (3) to apply the changes and reboot (remember to change the settings after this guide)

  (3) check the drivers failed in the log (C:\Windows\ntbtlog.txt) file (in my case I got "ucx01000.sys" driver failure)

  (4) after researching online (Source) I saw the USB3.0 stack consists of 3 files of accommodation with the xHCI Host Controller: Usbhub3.sys, Ucx01000.sys and Usbxhci.sys.

  (5) restart the laptop and press 'ALT + F10' to enter in the menu ACER recovery

  (6) select "Troubleshooting", then "Advanced Options", then "Command Prompt"

  (7) you will be located in the "X:" drive and the folder "system32" of the recovery unit

  (8) write "cd drivers.

  (9) "copy write Usbhub3.sys C:\Windows\System32\Drivers\" (if you are asked to overwrite, answer "Yes")

  (10) "copy write Ucx01000.sys C:\Windows\System32\Drivers\" (if you are asked to overwrite, answer "Yes")

  (11) writing "copy Usbxhci.sys C:\Windows\System32\Drivers\" (if you are asked to overwrite, answer 'Yes')

  (12) write 'exit '.

  (13) restart your laptop, and you should be able to use USB again

  (14) disable the startup option if you used Option B.

  In my case, the "Ucx01000.sys" file was missing in the drivers folder.

• Aspire driver E5-551 Windows 7 Universal Serial Bus (USB)

  I installed Windows 7 in Acer Aspire E5 - 551G, but there doesn't seem to be an operating system that is supported by ACER, because on the page to download ACER drivers, drivers are available only for Windows 8.1

  I found manually and installed successfully the various drivers for Windows 7, but I'm not able to find the appropriate driver for the "pilot of Serial Bus universal (USB)", and I guess that's the reason for a USB connection that does not work.

  Anyone know which is the correct driver?

  Thank you

• External drives, USB, USB Flash Drives, "driver software device is not installed. Problem Acer and Windows 7

  Not sure one I'm more frustrated with.  Acer or Microsoft

  Try to get decent customer service out either seems so difficult.

  OK, it's a pretty common problem.  I've seen this around other forums and each finger to Microsoft points.

  Flash USB, Jump Drives thumb drives, Memory Sticks, players, whatever they are called, they do not work on my Acer laptop.  Everything works still perfectly on my Vista PC and my work XP.  So they are not damaged.  Also an external Freecom USB 1 TB drive.  Does not work on Windows 7.

  I have an Acer 5338 (less than one year) which unfortunately as as a manufacturer OEM for Microsoft Windows are not interested in help to say that there is problem Acer.  ACERS site does not even recognize the existence of the cell phone model I which makes contact them for a solution physically impossible (everyone has a phone number or e-mail address >).  In any case, they had a free upgrade to Win 7.  (Oh you can't imagine how much I care that I didn't...).

  So I've updated.  And all USB memory devices do not work all of a sudden.

  All of them try to load drivers then give up with the error message.

  Just to get the usual answers to the road!

  • I tested the USB ports.  All work.
  • I uninstalled all the USB ports and let the Win 7 to reinstall. No problem
  • I deleted the file that records discs.
  • I made a new clean install.  Nothing has changed.
  • Cannot switch the chipset drivers.  Won't let me, says I don't need them
  • Each drive is displayed during the startup screen.
  • Each drive appears in Device Manager but the poster as a fault.
  • Updated installed, removed, re-installed all the drivers on the planet.
  • Tried the solution of "regedit" suggested elsewhere, temptation of power my laptop, lucky I system restored to the top.
  • Does not appear in disk management, so cannot deal with any drive letter conflict.
  • Have no viruses.
  • Have one firewall installed.
  • Prayed
  • Touched the thing of reversal
  • Pleaded
  • Pretended to cry.  Not interested.

  So, I'm hoping against hope that someone has a solution to this problem.  I have a vague idea that it might be something to do with the "ports" and the port settings.  I'm afraid is a closed book to me, so please, geniuses everywhere, please help!  Give me something new to try!

  Or a way to talk to a human being at Acer!

  Hi davec07510,
   
  We use Windows 7 and have not encountered this problem on computers. This issue is occurring on your computer may be due to the driver or hardware that does not support Windows 7.
   
  The compatible chipset driver installation Windows 7 can help.
