[Q] usb serial driver

Where can i download a free serial usb driver for windows smartphone?

What do you want to do? Serial interface is already included via Bluetooth (incoming and outgoing port) - not sure about USB, despite AS connection in "not enhanced mode (RNDIS)" is said to be "serial" as well.

I need the driver to connect my smartphone to a new pc via usb. My old pc crashed recently and i wasnt able to backup any software. Also, ive lost the cd which came with the phone and i dont know where to get a replacement.

You need a driver for the PC, not on the device. I have no experience with new OS, only Win XP. What happens when you connect the device via USB to the new PC?

My os is winxp. When i connect to the pc it says "found new hardware generic serial" then it brings the found new hardware wizard . I cant continue since i dont have the recquired driver on a removable disk or anywhere on the pc.my phone is spv c600

You need to install Active Sync first on your PC. This should install also all needed drivers for the device to connect. Look here: http://www.microsoft.com/downloads/...34-6f7f-404d-a04b-dc09f8141141&displayLang=en

I have already installed activesync 4.5 but i didnt see it install any drivers.

Is WinXP on the latest Service Pack (SP3 I think) and does it have all Microsoft patches installed afterwards?
AS install should put the drivers to the repository for later install when needed - it will not install the drivers right away. Why don't you let the driver's install look for the drivers in the internet - I don't remember any similar problems on my PC.
Search Microsoft for USB serial driver and RNDIS driver for XP if install does not get it for you automatically.

Oh! It has dected the phone. I reinstalled it while the device was connected to the pc and it worked . thanx so much

Check cables first, then try different USB ports. You may also check installed drivers in device manager.

Your phone is in Tethering (USB Modem) mode. You need to put it back in Zune mode before it will sync with the PC. On the offhand chance that you got it into tethering mode by accident, there are instructions on the forum for how to change between the modes. Note that USB tethering is not the same as the WiFi "Internet Sharing" feature that is built into the OS; I believe that USB tethering uses the Diagnostics app on Samsung phones.

Phone not recognized in Download mode (trying to root / update with .kdz)

Phone model H955, Windows 10 x64, following drivers installed: LGUnitedMobileDriver_S51MAN313AP22_ML_WHQL_Ver_3.13.2 (which installed LGE Mobile USB Modem AFAIK)
In download mode phone is recognized as LGE Android MTP Device and there is no adb interface in control panel, also it doesnt install the device and it says CODE 10 (This device cannot start).
When i connect the phone when it's booted (normal mode), it correctly shows my phone's name and adb interface (with usb debugging enabled).
Any idea what is wrong? (and yes im connecting using USB2 port, using original usb cable)
Im about to give up, this is beyond stupid.

Let me add screenshot to show how it looks like, maybe it's supposed to be like this. (?)

same problem here, any fix, only flash tool works even installed the drivers 4.0.4 to test and the same result error code 10 but if the phone is on the,driver works fine the, usb debug is always on
link for 4.0.4 driver

This may be a bit late but did you manage to fix it?

Same issue on my H950 G Flex 2. Been searching for weeks for a driver that works in Download mode.

QPST is only for Qualcomm based modem included devices.

Galaxy S6 = "unknown USB device" ?

Hi, since Samsung has finished support for Galaxy S6, i'd like to install the latest lineageOS on my SM-G920F. It has the latest (and last) official Samsung ROM (Nougat) and recovery and is not rooted, so I have to establish a USB-connection to a PC. But when I connect the device to my computer, it won't be detected. I've tried several different connectors on 3 different PCs running Windows 7, Windows 10 and Ubuntu 16.04 LTS. But the device never gets recognized, neither in working nor in download mode.
When I connect it to a Windows PC in download mode, I receive a message on my PC, that an unknown device has been connected. Now I start the "Zadig" tool (part of the heimdall suite for windows) to install the drivers and make it list all devices, but it just shows me an unknown USB device with VID 0000 and PID 0002.
Samsung drivers are installed on Windows PCs
USB debugging is enabled on device
ADB and heimdall are installed on Ubuntu PC
Any suggestions on how to install TWRP and lineageOS with or without USB connection?
