With this port you could plug in any hardware that is USB compatible into it. These hardware were made in such a way that they tell Windows what hardware they are and which drivers are required to be loaded to get them working. But soon hardware manufacturers started making changes to their Plug and Play or USB hardware and the generic drivers that comes packed with Windows failed to run them or could not give all the designed features to the user because of the limitations of the generic device drivers.
However, some hardware like Plug and Play USB Devices, Printers, Modems, Phones, scanners, external hard disks or storage mediums like cd roms, dvd roms etc may come with their own Device Driver files. This is because the hardware manufacturer wants to give many more features than what the generic windows plug and play drivers can give your hardware. Most of the plug and play hardware works with the Windows plug and play drivers. But many of them fails to even get recognized by Windows so even the generic drivers will not get installed for them.
It is advised that even if Windows installs plug and play drivers it is always better to use the Drivers that came with the hardware beacuse the Windows generic plug and play drivers are as old as Windows whereas the driver disk your hardware manufacturer provided has the better drivers. But again it is better to go to the original hardware manufacture website and download the latest drivers for your hardware.
Where are these Plug and Play Settings stored? All the changes you make are stored into your Windows Registry. A few of the registry paths where you can find your Plug and Play settings are given below.
What is Windows Registry? How does Plug and Play Drivers run in your Computer? Most device drivers including Plug and Play Drivers are designed to run in the Ring 0 or Kernel level. Some of the devices drivers are designed to run as File System driver, and some like Network adapter.
Click "Start" button, input "cmd" in the search box, right-click the program and choose "Run as Administrator" option. Step 3. Next type and execute all the below commands one by one. Step 4. Step 5. Attention : remember to change your BIOS settings concerning the boot order. You need to put the bootable USB drive first. But the key might be different from one manufacturer to another. I'll have to reboot the server again, which I cannot do right now.
Seems to be versus sector sizes, however could not verify that this is a R2 issues. I ended up using a different drive, this was taking too much time and not worth the effort to resolve. Having the same absolutly bonkers issue, we bought 5 exactly the same USB drives for backups and have been using them on a Windows Server SBS for about 2 years now with no issues but lately Friday's backup has not been getting recognised by the Server in any of the USB ports.
Other drives work fine and the drive that doesnt work on the server works fine on any Windows 7 machines with no corruption or bad sector issues etc. Very strange problem. Anyone ever work this one out? Every now and then the drive drops out of existence like described in this post.
Reboot the server and my USB drive is back. I have determined the problem to be related to the USB storage devices listed in Device manager being turned off by power management. I have. Edited the service to restart service on failure it was set to do nothing. Thus far, problem has not recurred - but in my case it was not a constant problem. I have a client and he was switching out the week setup prior to me on backup exec and it gave him a message about reformatting.
He unplugged the drive and back in and now none of the drives will show up. I tried rebooting but didn't work. I also found someone said to uninstall the usb controllers and reboot but that didn't work either. I have him now setup with crashplan but I would like to have a daily local backup also in case of a catastrophic failure. I don't want him to buy new drives when these should work as they work in every other computer I plug them into.
I tested a flash drive and that worked so the ports are good. Feedback will be sent to Microsoft: By pressing the submit button, your feedback will be used to improve Microsoft products and services.
Privacy policy. When a device is plugged in to a Windows-based computer, the Windows USB stack enumerates the device, extracting details from the device including the interface descriptor or descriptors of the device, and then generates a set of hardware IDs and compatible IDs for the device. Note that the vendor, device, and revision numbers are always stored in hexadecimal format. The generation of the compatible ID for the device is more complicated. The class code, subclass code, and protocol code are determined by the interface descriptor's bInterfaceClass , bInterfaceSubClass , and bInterfaceProtocol.
