Hi
my phone is running blisspop , cmw touch is installed . when i try to connect my phone to my PC , error message saying USB device not recognized , and saying device is malfunctioned.
i tried everything.
tried my phone with my friends laptop
changed usb cable
tried same usb with my friends G2 which is working fine. so this is not issue with USB cable.
so i tried to flash kdz to get rid of problem, i entered my phone "Download mode" my pc still displaying same error message.
is it hardware related issue?
It could be a hardware problem. I'm going through a similar case (but it's not a hardware issue though). By default you shold turn off the phone, connect the usb to the PC (not the phone) and then Hold Vol+ and Power, Until you see it entered download mode, THEN you plug the USB port to the phone.
install driver

I've got a couple of strange problems with my mogul - anytime I need to reset it, it goes into bootloader (both soft and hard resets). However, If I connect it via USB to my pc, the reset will work.
The second problem is a USB connection to the PC only charges the mogul, the pc doesnt actually recognize it (it doesnt give the windows device connection sound)- so i cant flash it to try and solve the first problem. It also isn't recognized when I plug it into USB while in bootloader mode, I just get the "Unrecognized USB device" error in XP and Vista on two different computers. It might be worth noting that I get the USB device connection sound when i reboot the phone, then the "unrecognized usb device" error, then the disconnect sound as the boot finishes and windows mobile loads. I've tested the cable with other devices and tried multipile cables, so I dont think thats the problem
Any suggestions?
Ok, I got the USB working but nothing will keep it from going into bootloader on reset if it isnt connected to my pc. I've reflashed and hard reset to no avail. no one has any suggestions?
I had this same problem w/ my fiance's mogul... as far as i know there's nothing you can do but take it to sprint and get a replacement... and just as an fyi.... i never modded her phone... it was completely stock!
I can believe my luck, receive an update notification but cannot install, my phone is no longer recognize by my PC, mini usb is gone but the phone is still charging...
I have the same prob.
Zune says, i should connect a phone. but its connected, butnt recognized. Its charge though.
(Windows 7 x86)
Go into device manager and see if it shows up there. Might be a driver problem. If that doesn't work, boot the phone in download mode (hold home+volume down+power) and if your computer recognizes the phone now and starts installing drivers, it's you computer, not the phone.
I have a bricked Lenovo K30-W I'm trying to fix (freezes on startup). My computer (Windows 10) won't recognise it when I connect it to the USB port. In device manager, the phone is displayed as unknown, with error "Device descriptor request failed". I tried connecting to different USB version ports, I tried installing multiple different drivers and software, but nothing helped. Adb doesn't recognise it as well, even if I boot the phone to fastboot with volume+power buttons. Any other ideas? Thanks.
Update: problem seems fixed. I used another USB cable and plugged it into an older version USB port. It is now recognised.
Help! i want to flash official firmware -GT i9500
In past i was able to flash via odin on same pc and now its not showing usb all driver installed
already try changing data cable and diffrent ports i even tried reinstalling win7 and diffrent version of kies and drivers
i dont have other pc or laptops . other samsung phone is showing on download mode on same pc.
odin only shows my phone when i pull battery while connected to usb on download mode and i can flash twrp recovery or
any small size file but cant flash full firmware its disconect after some seconds
it connects well on mtp mode and twrp.
I have the same problem with my S4. I tested J5 2016 and it is connecting properly with the same cable, drivers, etc, either with odin or in normal situations when phone is on. also S8+ connects with its cable and same drivers, etc. But S4 is repeatedly connecting-disconnecting, either in downloading mode or normal situations.
I installed this driver "https://developer.samsung.com/galaxy/others/android-usb-driver-for-windows" which is "SAMSUNG USB Driver for Mobile Phones 1.5.51".

Already tried it didnt work. i dont have disconnecting issue on normal mode i can send and recive via usb mtp to pc for your disconnect problem if it disconnect after phone screen off, go to control panel>sytem &security>power option>change paln setting>change advanced power setting>expand all usb setting =enable change to disable.
If anyone has solution to OP please reply
Thank you!
I eventually succeed! Nothing special just used my brothers' laptop (win 7). same cable, same driver (1.5.51).
My primary problem was WiFi and Bluetooth not working. I was hopeful flashing will solve it but unfortunately no. Seems a hardware problem.
With your recommendation (enable to disable) i saw no change with my pc (win 7).
So I have this strange issue, when i connect my phone windows says "Usb device not recognized" and my phone is just charging without any notification for file transfer option. even tried usb debugging no results. When connected in fastboot mode windows doesnt even show usb device not recognized. no action in windows. I have tried almost all basic fixes and also have replaced the entire charging board. The bootloader is locked.... and i wanted to mod the phone but unfortunately it doesnt connect to pc.
