USB or Flash drives are the choice of many users, as far as data transfer among different computers is concerned. However, at times it may happen that yourUSB devices are not working properly and they led to poor user experience. For example, when you plug in issued USB devices, they either do not show up or if they show up, became idle after few seconds of inactivity. In other cases, we found that when we try to access files on these USB devices, Windows File Explorer hangs for almost 1 or 2 minutes.
Most of the time, we carry important data on our USB devices, and if the issue of not charging occurs, we might not be able to finish our important work which follows the path via USB drive. Therefore, it is necessary to fix these random issues, so that we can use USB devices without any hitch. Before trying the fix mentioned, we suggest you check your USB devices to plug different computers. This will clear if the USB device is not malfunctioning and if it is working fine on other systems and not on your Windows 10/8/7, follow this procedure:

1. Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.

Extract the archive to your Dragon Age 2 override folder (DocumentsBioWareDragon Age 2packagescoreoverride). You do not need any of the other files for this to work. They were just requested by people in the comments page. For what the other files do, read on.!!! WARNING: SPOILERS BELOW, CONSIDER YOURSELF WARNED!!! Bethany will accompany Hawke to Kirkwall if you play a warrior or rogue. She is the only one of the two siblings who doesn't hold any pre-existing rivalry with Hawke, although she shares the same.
2. When the Device Manager window opens, you have to seek the USB device with whom you’re facing trouble. It may be listed under Human Interface Devices as USB Input Device.
If you don’t find it there, you can expand Universal Serial Bus controllers. Here, you’ll find a list of USB devices you’ve connected with your system so far. To find the one from the list for which you have an issue, you have to follow the trial and error method. That is, plug and remove the device and note the changes among the list of devices for Universal Serial Bus controllers. The entry which is appeared and then removed subsequently is the entry for the issued device. Keep the device plugged in and right click on this entry, pick Properties.
3. In the device properties window shown below, switch to Details tab. Now click the drop-down menu for Property and select Device Instance Path. Note down the corresponding Value because we will need this value in further steps. By the way, this value is a combination of three IDs; namely Vendor ID (VID), Product ID (PID), Instance ID.

5. Navigate here:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumUSB<Device Instance Path>Device Parameters
Substitute the Device Instance Path part (after USB) obtained from the step 3.
6. In the right pane of Device Parameters key look for the DWORD named EnhancedPowerManagementEnabled which must be showing its Value data as 1. Double click on the same to get this:
7. In the above-shown box, change the Value data to 0. Click OK. You may now close the Registry Editor as well as Device Manager.
Reboot the machine to get fixed!

I am very new to USB interfacing and i am trying to build an application for WINCE 2013 device. In my device, one vendor's (let suppose 'X') VID and PID are using for USB mass storage device class.
Now, i have specific use case where communication should be built on USB rndis class. For this communication purpose we are using microsoft generic rndis driver as is (not a custom one). So, can i use the X's VID and PID(which i am using for MASS STORAGE class now) for the Rndis class too or need to purchase a new one again. I know that i can use any VID and PID during development stage but i need VID and PID's for production devices.
Or can i go with Microsoft VID, PID and compatible id's compatible for Microsoft generic rndis driver by changing only the Serial Number for devices?
Please suggest and thanks in advance! :-)
(Do let me know if the query is too vague to understand.)

It's difficult to find a definitive answer, but maybe we'll be able to extrapolate from this post by a Microsoft MVP (emphasis mine):
(..) you don't have to change MS's VID/PID anymore if you use USB RNDIS to use ActiveSync.
Here's the official response from Microsoft on this subject (as asked by a fellow MVP regarding a client who had the same issue):
Question: Should they use the Microsoft PIDVID or create their own? If they create their own, it means modifying the current .inf file and therefore this means the driver will be unsigned and therefore may not be able to be installed. In the past the Microsoft PIDVID gave warnings to not use this. Now in 6.0 the warnings do not appear.

This is a change from documentation which says to get your own PID & VID. Contrary to what the sample Registry file says, the OEM should ship the device using Microsoft's VID & PID for USB-Serial ActiveSync client. The latest OEM documentation confirms this (..)
Now, since you don't specifically mention ActiveSync, my understanding is that the above probably does not apply to your use case, which again means you will have to use your own VID and PID.
If you already own a VID/PID combination, I don't see any (legal) issues using this with RNDIS as well. It is the same device after all, and the USB host would load one of two different class (not custom) drivers to communicate with the device.

However, if you use your own VID/PID you will have to either
- supply a signed INF file to end-users that contains your custom VID/PID, or
- instruct users to manually select the RNDIS driver when your device is connected to the PC for the first time
