Who hasn't faced USB problems at the most inconvenient of times? Every one of us is aware of what a USB is and what it does. USBs are an inseparable part of our daily work. It makes life easier by making data storage simpler. But as with any piece of hardware ever produced, it is bound to run into problems here and there. One such problem is when your PC is unable to recognize the USB device due to an issue in your USB Port. The error message accompanying this problem reads 'unknown usb device port reset failed'. This is the error that we are going to be focusing on in this article. Starting with the causes, we will move on to the fixes for this error. We will also introduce you to an amazing data recovery software named 4DDiG data recovery in case you end up losing data while fixing this error.
Running into a USB error especially when you need to get important work done is an unparalleled annoyance. USB-related errors signify a problem with the USB device descriptor. It means that the USB port is not able to recognize the USB device inserted resulting in an error reading a usb port reset request failed.
A port reset failed error is intricately tied to its cause as the cause of the error determines the fix to be employed. Not knowing the exact cause of the issue can send your approach into disarray leading to confusion and frustration. So let's look at the possible causes that are behind this error.
Sometimes the error may not lie with your PC at all. That's right, if a USB cable is defective it may lead to an error message. So get hold of a different USB cable and try to plug in your hardware and see if it solves your problem.
Before jumping to conclusions about your USB Device it's a good idea to check other USB ports in your PC to see if it's a generalized issue or a case of a single USB port malfunctioning. So insert your USB into different ports to see whether it is working.
It may turn out that the issue does not lie with your USB at all, that it is the PC that's causing trouble. This may happen due to hard drive problems in the PC, outdated drivers, etc. Try connecting your device to a different computer to check if your USB is functioning properly.
It's always a good idea to use the troubleshoot feature in Windows when dealing with hardware issues. It pinpoints issues that are plaguing the hardware and rectifies them. So how do we use this feature to fix the unknown usb device (port reset failed) problem, here's how.
Step 2: The Hardware and Devices troubleshooter window will now emerge after you run that command. Press the 'Next' button to start the troubleshooting process. Let the troubleshooter run its course.
Step 2: Once in the device manager, look for the 'Universal Serial Bus Controllers' category and expand it. In this category locate the malfunctioning USB drivers. They are usually marked with a yellow sign of 'Unknown USB device'.
Step 3: Right-click on that USB and from the menu, select the 'Uninstall' option. Once complete, restart your device. Windows will automatically look for new updates for that USB and install them. If not, you can do it manually by downloading the required drivers.
USB selective suspend feature is a nifty tool to save power when a particular USB port is not in use or inactive for a long time. It occasionally leads to errors like the usb port reset failed. If the suspend feature is what is causing this error then disabling it is the best way to go, here's how to go about it.
Step 3: Now an elaborate menu of advanced options will open up. In this menu, click on the drop-down category labeled as 'USB Settings'.

If there is no problem with the USB port on your computer or the USB device, try the solutions given below. You can start with the first solution and work your way downwards and try other solutions until the issue is fixed.
(Note- the driver files are available in a variety of formats such as EXE, INF, or ZIP files. The above steps would work when the file format is ZIP or INF. If the driver file is in ZIP format, you need to unzip the contents and then follow the step above. If the driver file in Exe format, you can straightway double-click on the file and follow on-screen instructions to install USB driver)
Driver Updater is one of the best driver update tools out there. Outbyte Driver Updater will give you access to a database of over 1 million drivers. It will regularly scan your PC, suggesting new driver versions to install. Driver Updater contains drivers for a variety of Windows devices. With just one click, you can update drivers in your system.
The Fast startup comes across as a good option to save time spent in booting and shutting down your computer. But it may be one of the reasons behind unknown USB device (device description request failed) error.
The fast startup works like hibernation where the state of the computer is saved as an image on the hard drive and the same image is used to boot up fast. When the fast startup option is enabled, Windows does not reload kernel drivers and that could be the reason behind USB error.
The USB Selective Suspend option is a power saving option that suspends power supply to selected USB port in an idle state without affecting other USB operations and USB ports. This feature could be a reason behind Unknown USB Device (device descriptor request failed) error.
Many people spend money unnecessarily replacing laptop batteries when they may have fixed the issue with a simple battery reset or a Drivers update. If you are having problems charging your laptop battery, then reading this post may save you a lot of time, money and frustration!
Unzip the archive and copy the usbdrv subfolder to your project folder (the whole folder, not just contents). Go to the subfolder and make a copy of usbconfig-prototype.h with the name usbconfig.h. Locate the #define lines for IO port and port bits and clock rate, and update them as necessary to reflect our configuration where D+ is in PD2 and D- in PD3 and clock rate is 12 MHz:
Another thing you may wonder is why the disconnect/delay/connect -procedure is needed at all. This is because the host PC can remember the identifier assigned to a USB device even if our device resets and forgets that identifier. By enforcing re-enumeration we make sure that both the host PC and our device have the same ID used to communicate over the USB bus.
Now immediately after you have flashed the ATtiny you should hear the standard Windows fanfare di-dum sound that tells a new USB device has been plugged in. Windows will look for a driver and most likely fail. This is where libusb-win32 comes to the rescue:
I could have a separate tutorial covering my trial-and-error methods of getting the USB device driver to install and work. I hope you have better luck. In case of problems, here are some helpful tips:
Congratulations! We are almost there! Now we only need to prepare the host-side software. For compiling it, I recommend the GNU C compiler gcc from MinGW project and the MSYS tools that you should be able to install along with it, but probably Visual C and others work just fine. MinGW installer is really hard to locate (big thumbs down for the wiki authors on usability), but currently trial and error should eventually get you here.
For those who want to understand the control messages better, I warmly recommend the surprisingly user-friendly USB 2.0 specification. The part on control messages starts on page 248 and the first table concerning this should be Table 9-2. You can find the download link for the spec from part 1 of this tutorial. The specification is rather simple and defined constant values closely reflect the #defines in libusb so you should understand everything rather well just by comparing the spec and my example code.
Now that we got past all the sillyness of helper functions to scan all USB devices and return their specially formatted descriptor messages in order to get one simple device handle, the rest of the code is very straightforward. Only thing making the USB communication different from standard structure of accessing a file are the calls to usb_control_msg(), otherwise the general structure of open / do stuff / close applies:
