The Driver Installation File For This Device Is Missing A Necessary Entry

[Mickie Bottiglieri]

Thankyou for the reply Sir.

I think it's a clone board like you said. but installing the CH341SER driver didn't help.

The driver status still shows Code 28 error. And I am stuck with my project

It does sort of look like an FTDI chip in which case the CH340 drivers wont help.

Although it really should work out of the box if that's the case there have been cases where getting the driver from FTDI themselves seems to have helped.

However there have been a lot of reports of the ATMEL 8u2 failing over the last few months.

Its unsure as to exactly how but seems to be linked to input voltages of 12 volts or higher on the power jack or shorts in bad wiring by users.

ICSP programmers are an almost essential bit of kit for Arduino users and I have at least 4 kinds here.

They are also useful to re-load bootloaders on most boards too and are exceptionally cheap from China.

Hello again.

Actually The problem is with my COM & LTP ports in windows 10.

when I plug this same board into another PC(Windows 7) with Arduino driver installed, it shows the Device in the COM & LTP ports without any additional configuration.

So its down to your computer.

Make sure its NOT a USB 3.0 port issue as Arduinos have been known to fail on USB 3.0.

Ensure DRIVER enforcement is OFF.

For testing turn OFF antivirus or similar software.

Ensure you don't have any other terminal software or phone sync type software running.

Everything is correct-

It's USB 2.0,

Tested after turning off Driver enforcements,

No anti-viruses and usual softwares are running.

And I have the the official Arduino driver.

Still does'nt work on my pc. but it does work on virtual box when I setup the necessary things.

But in my pc, it doesn't shows COM ports. And shows a Code 28 error!

Since you have Windows Enterprise, your IT department may have configured Windows to prevent driver installation. This is to prevent users from accidentally installed malicious software such as ransom ware.

There is no simple "patch" for any of those items mentioned.

Worst case scenario on a badly set up box or one that has been messed with is a complete re-install of the OS.

In the case of a locked down box that would be between you and your IT admin to sort out especially if it involves bitlocker at all.

Worked great for about 3 months, but then it starting having this issue where Bluetooth wouldn't be available. I tried re-seating the wifi card. Replaced the little wifi cables that go to the antenna.

No device at all shows up in device manager. (When I browse hidden devices and go to Intel bluetooth, it reads: Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer.)

Note that it sometimes takes multiple uninstall (and reboot) cycles to clean out the old installations, so don't give up on the process. If you get to, say, 10 cycles, stop there and attempt the installation of the latest drivers.

The problem is mainly because the drivers provided by vendor does not support windows 10 (this happens if you have migrated from windows 7 or windows 8.1).Reinstalling the bluetooth driver (Programs and Features)only would solve the problem.

I had to open a ticket with the Intel support because uninstalling / repairing / installing the right driver wasn't working. The solution was to enter in the BIOS and setup the default setting. After reinstall the Bluetooth was back:

I have a Dell XPS 13 9350 and had to do a reset of the BIOS to fix this. No idea what had changed in the BIOS, but multiple restarts didn't help. After resetting the BIOS to Factory settings (not BIOS Defaults, but I didn't try that), Bluetooth worked as expected again.

Most of the solutions here did not work for me. In my case, my laptop had an Intel Wireless Bluetooth driver. After searching for that, I ended up on Intel's website and downloaded the latest version of the driver. After running the executable and doing a "Complete" install, I restarted my machine and the Bluetooth switch returned to the Settings window.

Another thing to consider, if you have a spare WLAN adapter / card for your laptop. You can also try to exchange the cards. Check if the Bluetooth afterwards works. Strangly for me it did with my old adapter as soon as I booted into Windows again. So I disabled Bluetooth, turned of the computer and switched my other one (previously not working) back in and it started immediately working again. The switch for turning on Bluetooth was showing up again and it was also listed in the device manager.

I tried most of the above listed suggestions but none did help or brought it back to life. However the quick swap did some magic. This seems to be a bug within Windows 10 because I'm pretty sure this wasn't a connection issue since the WLAN worked flawlessly. Another thing to note is that a driver update of either the WLAN or Bluetooth broke the Bluetooth functionality.

So if you have a second one lying around and don't want to tinker with software methods which probably won't work if you your adapter disappeared in the device manager try this out. It might be a quicker fix.

I had to do a system restore because I had previously installed the "ScpToolkit", which is for connecting a Playstation 3 Dualshock controller to your computer via bluetooth. It seemed to screw up the bluetooth on my Acer laptop completely.

I also tried uninstalling everything related to Bluetooth in Device manager and then reinstalling some of the Bluetooth drivers found on Acer website for my laptop but those didn't do anything. Bluetooth still wasn't showing up on Device Manager (even though I turned on View --> Show hidden devices).

I noticed I had another issue too that when I go into device manager, I was constantly refreshing after every little while. I figured I should perhaps fix that first and following up, it indeed was connected with bluetooth driver. When I uninstalled the bluetooth device, the refreshing stopped.

I had the show hidden devices option enabled from view menu. There were several items listed under blutooth (previously connected device). I uninstalled them all but they will come back when scan for new devices.

Another suggestion I can give you is if you can somehow force this dialog (posted above) to come and selected `Allow bluetooth devices to find this PC' (this was the deselected when the dialog came up), that seems to apply the proper settings too perhaps.

The problem returned after reboot. I searched "bluetooth" in installed programs for drivers and I had two different ones installed as listed bow. Uninstalling the WIDCOMM Bluetooth Software and rebooting fixed the issue for good. (First I let it stay and uninstalled the intel one but that didn't fix the problem).

For instance, I have a VMWare client running on my work laptop. Today I discovered I was unable to use my bluetooth headset for a Zoom call on the laptop. The Bluetooth button in the Action Center was gone, and the Windows 10 bluetooth settings for my headset said simply, "Bluetooth is turned off".

After looking around for a while, I realized the VMWare client window was stealing the USB bluetooth adapter from the host (the laptop), as shown below. Once I unchecked that, all bluetooth features on the laptop came back:

I had recently changed out a mouse peripheral, and removed what I thought was the dongle for the old mouse. However, it turned out the dongle for the Bluetooth Adapter and the old mouse/peripheral dongle were sized & shaped exactly the same (with no branding).

So, after a while I realized the issue was less technical when Windows reported that there was no Bluetooth Capability - got the old mouse of the recycling bin and switched to the correct dongle... Yes not the smartest of solutions, but someday will hopefully help another person from unnecessary debugging

dont download any of the above as they are possibly viruses that can harm your computer. please download the original ITUNES and extract it into WinRar, then drag the apple mobile support driver thing into your desktop, and proceed to installing it from there

I had this issue on Windows 10. I did not have a "C:\Program Files\Common Files\Apple" folder (or in my case since I have Windows 10 x64 "C:\Program Files (x68)\Common Files\Apple". I installed iTunes which gave me the C:\Program Files\Common Files\Apple\Mobile Devices\Support\Drivers folder. When I tried to update the driver for my iPhone on the PC pointing it to that folder, it told me that I already had the latest driver.

However, the next time I connected the iPhone, the computer gave me the Trust/Don't Trust prompt. Prior to that it was just the iPhone asking me if I should allow the computer to access my photos, there was no trust prompt on the computer.

Done it. Well...until I got to the part where it wanted me to disable USBs that would also disable my keyboard and mouse functions on my laptop. Kinda don't have an extra keyboard or mouse lying around to connect up to. Oh, and it stated earlier to disconnect anything connected to the USBs anyway, so exactly how would I connect them if I can't have anything connected with the USBs? Aaaanyway...I'm just about to rip my hair out.

Oh...OK...they must have meant if you're using a desktop pc. Those articles are so confusing if you're not an expert...lol. Thanks. Guess I'll give it another try. ;O) Oh wait...Yeah...I've done the Stop & Start service thingy for bothe the Apple service and the IPod service to no avail. The article I was referring to was the one about trying to find the missing mobile device USB driver and repairing or reinstalling it. That's the one that's messing me up.
