Ask to read a USB device descriptor

Similar Questions

• USB device descriptor found where?

  1. There a registry tweak described in Microsft Support for Disabling active usb ports- it requires the creation of a key in: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags
  2. It sounds simple enough, but the key must be given the name of the USB descriptor.  Is this available in one place or it is necessary to dig across this line merged?  In both cases where information can be found?  The problematic section of the tutorial goes like this:
  3. Type the name of the new key in the following form:
     vvvvpppprrrr
     -where vvvv is a 4-digit hexadecimal number that identifies the provider (idDevice, starting from the USB device descriptor).
     pppp - is a 4-digit hexadecimal number that identifies the product (idVendor go USB device descriptor), and
     -rrrr is 4-digit binary coded decimal number that contains the revision number of the unit (bcdDevice go USB device descriptor).

• Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor has failed.

  Separated from this thread.

  Hello

  I'm faced with the same question. I went to settings of your laptop and ran the recovery, but it did not help. I went to Device Manager and I noticed an error: Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor has failed. Tried to fix that with an alternative of Microsoft Community (http://support.microsoft.com/mats/hardware_device_problems/?wa=wsignin1.0), but the issue could not be resolved. I don't know if they are related, but I think so. Spent so much time trying to solve this problem and would be really grateful for the help. Have had the computer for less than 3 weeks...

  Hi Ewa,

  Thanks for the reply.

  I suggest you to update the drivers for the chipset of your computer and check if it helps. You can use the link below. Select the appropriate component and the operating system from the list. The link given below is for Lenovo 11 2 yoga, if you have any other device then please provide us with the exact model number or select the correct model number.

  As you mentioned that the other two USB ports work correctly, according to me is not a problem with the driver. It seems to be a hardware problem.

  Let us know the status.

  Hi waly,.

  Thank you for the information. I suggest that you unplug all USB connections and refresh your laptop. Then try to use your webcam. I think that the problem with the USB connection that gives you the error and not your webcam. Here is a document on how to update your PC to solve problems (Windows 8).

  If you are still experiencing a problem with the webcam and then one of the documents in the previous post should help now. Any stage of document Windows 8 will be the same for Windows 8.1.

  I'm also including this document how trouble Code 43 errors that will help determine which USB product causes the error to appear.

  I hope that this information help, please let me know how it goes.

  Good luck and have a great day!

• Windows 7 does not recognize FAT32 formatted devices / Windows asks you to format a USB device in FAT32

  I have a question about Windows recognizes only not USB devices formatted in FAT32.

  The biggest symptom is Windows asking to format any device that has FAT32 (indicates RAW file format in disk management. The format will fail unless NTFS is used (which is unacceptable for the SD cards used in cameras, etc.).

  I have a Toshiba Satellite P755 with USB 3 port and three USB 2 ports, running under Windows 7 64-bit. Type computer apparently and for most device type is not relevant to this subject after doing some extensive research.

  1. I tried SFC / SCANNOW with no result

  2. I uninstalled all the USB drivers and drivers of devices on SD card with no result

  3. I created a new profile and flies over my files with no result

  4. I searched the net and found a plethora of people having the same problem on several versions of Windows but not confirmed of the solution.

  5. I tried the fix for troubleshooting of hardware from Microsoft with no result.

  The devices I've used are pen drives, to several types of SD cards flash drives and external hard drives. These devices are confirmed to work on several other computers configurations in different windows. When formatted in NTFS all works but like I already said, SD cards will not work in the cameras etc. to NTFS.

  I think that the computer of wiping and again is not the problem. After researching, I discovered this problem has been around for many years and followed by Windows XP throughout Windows 8 forums and blogs that I read. I'm surprised Microsoft doesn't have a fix for this yet.

  Hello and sorry for the delay.

  I tried this before with the same results. My pen drives and large SD card worked until the problem occurred. Windows 7 has lost the ability to recognize the FAT32 devices.

  I think I found the problem, however. My USB key must have failed in some way. After checking all my media work properly on a free desktop running windows 7 64, I jumped into a thumb sansa player and that's when I started having errors on this computer as well. This time, no data survived.

  I went back to my laptop and formatted by a new copy of windows Professional 64-bit. The laptop works great and recognizes all FAT32 media I throw at it. I do not use the USB key suspect for fear that it might cause problems again.

  And so far so good a few weeks later. Everything works great. I used FAT32 media without any problem. I'm sure it was the reader. I guess that he worked at masked the fact that it was the cause of the problems. Strange that this would produce windows FAT32 to reject.

• My c309a keeps asking to remove the usb from the printer device.

  This message appears on the printer, although there is nothing in the printer.  I think that alluded the bridge pic, because it never happened until I hooked up my camera to the printer.  Now, it gives me this message every now and then and it makes it feel a little awkward especially when I try to print from my android.

  Is there a cable plugged into the front USB?  What exactly is the error message?  Have you tried the c309 power bike?

  I was going to suggest that the only USB front supported PictBridge, but I was just pleasantly surprised to plug a USB flash drive and find that the c309a does support fron printing and scanning of USB devices other than the PictBridge devices.

• Interfacing with several unknown USB devices; all producing NMEA strings

  Hi all

  Question about the peripheral USB interface and their associated drivers.

  I have the obligation to build an application that interacts with the USB devices that produce NMEA strings. I have the library to parse NMEA strings, but I fight with interfacing with several unknown USB devices. When deploying applications, I know not all possible USB devices to use.

  Is it possible to produce one driver who will accept any USB device strings?

  Or, more likely, is there a way to get the LV to recognize a connected USB device and automatically find / install the driver like windows does and is it possible to do in a deployed application?

  I had a trawl of the forums, but I've not found anything that specific.

  Thanks, I really appreciate the help.

  About the VI "set up the serial port", my problem is that the choice of COM port is in a separate menu (not directly related to the VI) and it allows all possible COM ports to be selected. That can be addressed.

  I am not expecting an all-in-one solution but asked the question in case it was possible.

  What I realized, is that for my specific condition to read strings from a USB device. It is likely to be sent over a serial connection. LV can handle this well and easily assuming the device has the installed driver / settings are available.

  LV (and indeed any other program) will not work without a device driver / settings. In this case, parameters set must be found (error) / a USB RAW driver would need to be developed. Devices requirng a RAW USB driver would need a serious review to continue due to the time and effort required. All this effort is work inherited from the AIDS to navigation

  I appreciate any help and I think I got the answer I was looking for! Thank you very much

  Hello

  1. What is the brand and model of your computer?
  2. What is the version of Windows installed on your computer? For example, Windows 7, Windows Vista.
  3. this happens with all USB devices?

  4. have you done any software or hardware changes on your computer before this problem?

  You can run the fixit mentioned in the following link.

  Method 1:

  Hardware devices do not work or are not detected in Windows

• What is the best/better way to reenumerate USB ports from a script? I need to emulate the same enumeration that occurs when a USB device is either plugged or unglugged to a USB port.

  I'm working on a network to restrict access to the ISSO role USB mass storage, only. Management wants to access USB Mass Storage for ISSOs on all workstations while blocking access to USB mass storage to all others... on all the workstations. They also want to that USB ports remain available for everything except Mass Storage.

  There are many ways to do it, but the only 'reliable' method, I found so far is to point the HKLM\System\CurrentControlSet\Services\UBSSTOR\ImagePath key to some fake file to block ports and rename it back to access it again.

  To do this, I need to do things more two 2...

  1. make sure that the ImagePath key always has the false value at startup, and

  2. create a login script that affects the ImagePath value when a member of the ISSO group connects... and reset it when they log off.

  Which meet the requirements of the direction if only it worked! The problem is that USB devices must be listed again to re-read the ImagePath registry key after each change. Reconnect the device will do, but it would be unwise to rely on a user to restrict access (fox/Coop).

  The following Microsoft KB seems to be the way to go, but we do not have compilers on the network...

  http://support.Microsoft.com/kb/259695

  I know that this hack to the system is not the most elegant, but I'm just trying to make the management happy.

  Nobody knows...

  1. any (more elegant) way to meet the specified requirement, or

  2. a way to re - enumerate USB devices from a script.

  Hello

  It doesn't seem to be a model available in HP you specified.
  See the site:

• Bluetooth mouse stopped working & USB device not recognized error

  Laptop using Windows Vista

  I was using my bluetooth mouse when I plugged my mobile phone (via USB cable) in charge. I have done this before w/o a problem (perhaps in another USB Port, now that I think about it) but I did this time and I instantly lost the ability to use my bluetooth mouse and the "USB device not recognized" bubble popped up. Now, this window pops up almost every 10 seconds even with disconnected USB mobile phone.

  I went to bluetooth devices trying to pair my mouse w / new laptop and I can not. It's not show my mouse and when I go to Bluetooth settings and try checking the box (and pressing OK) under the discovery that reads "Allow Bluetooth devices to find this computer" it gives me an error saying that this is impossible.

  Help!

  The manufacturer of my hardware (bluetooth mouse) will not be able to explain why this struck dead window device unrecognized USB is coming non-stop. Above tutorials did not help at all.

  Hey wsdp

• My USB devices are not recognized, but they have a power

  My USB devices are not recognized, the only ones to be recognized are my mouse and keyboard. Each device is powered (motherboard works fine), but Windows 7 isn't their read (although sometimes I'll get a code 43). I have the latest chipset.

  I tried right click and uninstall each device and rebooted the computer. Nothing has fixed this.

  My external hard drive, ipod and other devices that involve the transfer of data seem to ONLY get power and nothing else.

  It is not material because all my devices work on my laptop. Also my motherboard works fine (it's the 2nd RMA) and it has been tested at the factory to make sure of him.

  I would really appreciate help with this

  Hello

  I would also ask you to contact the manufacturer of the computer to help.

• Handspring Visor is a "unrecognized USB device" for Windows XP

  Hello World-

  I feel as if I have a career to synchronize my PDA hot! I used to hotsync regularly on my old HP Windows 98 machine, and now that I have this new (er) eMachines Windows XP Pro system, I got nothing but heartache. Here's the situation:

  My Visor Deluxe runs Palm OS 3.1H3, apparently the latest version which will work with it. The computer is running Windows XP Pro SP2. I have hotsync a few times when I got to the computer, but it has never been reliable. Now I surely CAN NOT synchronize! When I press the button on the cradle, Windows hotsync ALWAYS reports, "USB device not recognized" and of course the visor says he couldn't make contact with the office.

  HotSync manager is running (I have the blue and red arrow on the taskbar icon), and if I look at the Device Manager when I try to sync, is apparently trying to get the driver, he simply painted the same list. The list does NOT include the Palm, Handspring or unknown devices.

  I followed the directions "clean uninstall" I found on this forum and re-installed Palm Desktop 4.01. That worked once a week or two ago, but now when I arrive at the end of the installation, when I'm supposed to hot sync, I get the error not recognized USB.  I even tried to install Palm Desktop software version 6.2, but which ended up in a mess - I was getting errors like "Ordinal 23 could not bewildered because of the trajectory messed up', or words to that effect... I think it's ok for XP, but not "peripheral" as my trusty old visor :-)

  I know I should try to use the same configuration on another computer to be sure that the visor is ok, but I don't have access to another machine; In addition, the PDA has no other wierdness. Soft resets do nothing, but I don't want to try a hard reset until I get everything synced to the top! I am at my wit's end and don't know what else to try. I tried both my cribs and a number of different USB connections both at the front and the back of the PC. The USB hardware in the computer seems to be fine with everything else - mouse, camera, mp3, flash drives. I'm beginning to suspect that I need to plug with USB 1 and these are 2 USB, but I don't know how to check either of these things, or how "throttle" in the case, I have to use the USB as soon as possible.

  Thanks in advance to everyone that these figures. I'll be very grateful to have everything works again.

  Gary Benson

  I was with you until the end. I hate to ask, but could you clarify this just a little:

  Then, reinstall your Palm desktop from the CD and do a hotsync. If she asks
  for a user name and you synchronized your device before you put "test" If you "
  no sync before creating a hotsync name.

  Ok. I read three "if" statements, and try to understand what is meant here. If they ask you a user name AND if I synced before, AND if I do not synchronize before creating a hotsync name, I put in 'test '. Means I can't use the name I used for this camera? Or are you suggesting that, really, should I open Palm Desktop and create the username before I hotsync for the first time (after the new installation)?

  I * have * synchronized before, and I don't plan to sync until everything is set up right, which to me should mean that Palm Desktop is ready with a username to match your handheld.

  Also, these indications seem in conflict which advised you to in the first paragraph, where you said:

  When you install Palm desktop, skip the hotsync process and complete the installation. After installation, adjust the conduit in hotsync manager for handheld overrides desktop, then synchronize with PC. During the connection process, it will ask you a username, enter the same username which is located in the upper right of the screen on your handheld hotsync.

  It * seems * that what you say I have to do is:

  (A) clean uninstall - move data to safe places, uninstall, and then remove all traces of "Palm" and "Handspring" of the registry.

  (B) restart the computer.

  (C) install Palm desktop, but not hot sync again.

  (D) open Palm Desktop, add the user name (Tools/users) and set the lines for handheld overrides Desktop.

  (E) hot sync.

  Isn't it? Sorry to be so simple, but I want to make sure to proceed exactly right. Thank you very much for your reply and for your help.
