Hi all a few days ago i installed Androids latest update and ever since then when i connect my HTC one to any XP device i get the error message saying it can't find drivers for CDC serial, Android or mass storage This is a nightmare for me and i can't seem to find a resolve. I have installed HTC sync but it will not pick my phone up is there anyone who can help me at all? Very frustrated as an update is not meant to stop my phone being fit for purpose I get the MTP enabled message on my phone as well At least is there a way of rolling back anyone else had this issue. I had the same problem with my HTC One m8 dual sim. After reading a ton of manuals and forums I finally figured the solution. First you have to download and install HTC Sync Manager located at their site here: 2.

If some drivers are failed to install you have to install them manually. For example, I had my CDC Serial driver failed to install at Windows 7: Go to Device Manager, Find the device, Do manual install from the HTC Sync Manager folder, located somewhere at C: Program Files HTC HTC Driver Driver Files Win7_x86 If that does not work, select manual install, pick from the list, select all devices, install from the disk, select that folder again, and pick HTC Sync Manager Serial Interface.

I've built my own PC computer from parts I purchased online, I did a clean install of Windows 7 Ultimate 64-bit with SP1 (full version, no OEM bloatware), and I ran Windows Update several times to get the latest and greatest updates from Microsoft. I was pleased to see that everything worked as expected, no issues whatsoever, not in software nor in hardware. Next, I connected my brand new Samsung Galaxy S4 Plus (GT-I9506) phone to a free USB port on the computer. Windows detected following 3 different devices. • USB Composite Device • Galaxy S4 (sg) • CDC Serial Windows automatically installed and configured the first two devices (see screenshot above). Except the 'CDC Serial' device.

It didn't install that one. Mortal Kombat 9 Pc Highly Compressed. • What is 'CDC Serial' device? • Why do I need it? • How do I install it? Zeiss Auriga Manual- Download Special Version more. The very first thing I did was to check the user's manual (the complete manual, not the getting started guide). There is not a single reference to 'CDC Serial'.

I'm not an expert, but I do understand some of this. The 'USB Composite Device' is installed so that Windows can communicate with the phone over the USB cable. The 'Galaxy S4 (sg)' is the name I gave to my phone during setup, and this is the device that presents itself to Windows as a media player, makes use of the MTP protocol, and this is what shows up in Windows Explorer. How am I supposed to know what 'CDC Serial' is if it's not described in the user's manual?

I have never seen that before on any Android device when connected to a PC. I did a search for 'cdc serial' on Google and all I could find was people doing some hacks to their phones, like rooting, changing ROM, and generally just hacking it.

If you have an HTC mobile phone then you can download this driver for the HTC MTC. Samsung CDC Serial Driver. [pc][sengoku Musou 2 [jap]. Aspire one d270-1615; download driver usb to.

So what if I don't want to do any of that? Is it still important to configure the 'CDC Serial' device? How does it impact the functionality of the phone, e.g. When syncing data between the phone and the PC, if I decide I don't want to follow those hacking tips and tricks to try to install this device?

I contacted Samsung Technical Support about this and they had no clue what I was talking about. They said they would look into it, but that's it. No help at all. The user's manual says I can change the USB connection type from MTP to PTP.

It essentially makes the phone present itself to Windows as a still camera device. I tried that there were no issues with drivers not being installed. Windows detected only the 'Galaxy S4 (sg)' device and it was automatically configured and installed. In this mode, only picture files can be transferred between the phone and the PC. So this is very limiting, in my opinion. But the 'CDC Serial' device was not detected.

I've never found Windows to be very helpful in identifying drivers either. Here's some information for you on what USB CDC is.

According to: USB communications device class (or USB CDC) is a composite Universal Serial Bus device class. The class may include more than one interface, such as a custom control interface, data interface, audio, or mass storage related interfaces. Additionally, a resource called the USB Software Resource Center has this: There are three classes that make up the definition for communication devices: the Communication Device Class, Communication Interface Class and the Data Interface Class. The Communication Device Class is a device level definition and is used by the host to properly identify a communication device that may present several different types of interfaces. All of that is developer-speak, but it really just means that a USB CDC driver helps your PC 1) understand what services your phone can provide it and 2) start talking to your phone to use those services.
