Pull down the notification menu (while connected) and select USB connection and you should get a option to turn USB storage on and off.
It also depends on which rom you are using.

It even could be your pc, reboot it. Has something to do with the non-mandatory safe removal of USB devices. I had it with my phone and I thought I bricked it.
Maybe your pc need the right drivers, reboot PC and replug the USB cable. Look at the notification bar if you see an USB icon, click it and turn on mass storage.
Hope this helps.

[Q] USB doesn't work

Hi
Yesterday I S-Offed my Wildfire and instelled CM7 rom.
But today I wanted to transfer some music to my phone and i couldn't do it.
When i plug USB cable into PC, my phone just charges and can't do anything more because phone doesn't show that it is plugged by USB. Just USB debugging turns on but I can't transfer anything to my phone.
Yesterday it was all OK but I flashed google apps and Jacob's kernel(v4.2). Maybe that is a problem.
I'm waiting for advice

I have a similar problem.
The phone also shows connect via usb option.
But on doing that, the phone does not show up on my pc.
When I go to "Disk Management" in computer management on windows 7, the disk shows up but I can't assign a drive letter to it and hence it is not accesible.
Can any1 help with the problem ?

Forgot to mention.
The problem does not appear when I connect my wildfire to my mac.
It shows up as as a disk drive when mounted.

I had a similar problem after installing CM7 so I got Multi Mount Sd-Card Lite from the market, put the widget on homescreen and click it each time i mounted my usb.
Hope it solves your problem!

Don't flash Jacob's Kernel v4.2. Keep the stock one.

Thanks for advices
I re-installed CM7 and kept kernel which comes with rom.
Now I have NO problem with that.
So it was kernel problem.

[Q] USB not working (on a custom rom)

Hi guys
I recently bought a defy plus (bl7) , rooted it and installed ms2ginger. Since yesterday it's USB is not working for data transfer or anything except for charging, the device wont charge even using the data cable, however it charges through a charger. I want to get it repaired since it's under warranty, but with custom ROM i can't. I have a stock sbf file with me, but it can't be flashed with no working USB. Is there any way to flash custom sbf through the recovery..?
things i have tried :
Used different USB cables
Tried on ubuntu, arch linux, windows xp, windows 7

Try this: http://forum.xda-developers.com/showpost.php?p=31062260&postcount=2
Does it charge on the usal power supply? If yes, get CM7 zip on your sd-card and flash it in cwm!

well, it does charge, but it doesnot really detect a USB cable connected to computer, it just gets the screenlight on, thats it. there is no option to choose which mode i want to connect it as... it charges only from the charger, and for USB connected to computer, it wont even charge, just gets the screen light on.
Even if i boot from recovery and mount my sdcard, it still doesnt shows up on computer.

Update : RSDLite detects it, flashed my stock sbf over it, i hope if i get a warranty.. but weird thing is.. if RSDLite works.. why not usb works on PC.. i tried this with linux and windows both, in linux it doesnt even populate this device in /dev node.. this is really weird, even stock firmware doesnt detect USB, doesnt even charges from it.. just gets the backlight on.. rest it charges through the charger. totally confused..

Another update, lsusb on linux lists the device, RSDLite always detects it..and it does let me flash perfectly.. on phone it occasionally detects USB... whenever it does not, if i toggle ADB option in settings, it shows that USB is connected in status bar, however setting value there has no change, but SOMETIMES it does detect the USB.. i dont think its a hardware fault, if it was it wouldnt be detected by RSDLite...
i have tried changing the rom too, tried ms2ginger, stock, and Cyanogenmod 9 and 10.. all give the same issue.. only one advantage i get in Cyanogenmod is that it charges over USB, that's it.. it detects it as a charger...
In recovery menu as well i cant mount it.. Please Help.. anyone? :crying:
By the way this issue is similar to this one :
but the solution doesnt work for me as i dont get phoneutils with that combo

SOLUTION
First
marcussmith2626 said:
the device might have trouble enumerating especially in windows 8.1
plug it in as normal
then plug any other usb dongle in like a wireless mouse thats already been installed
this will force windows into enumerating the device
if it doesnt work then most likely the port is damaged due the water damage it suffered

it took me months to figure that one out - even microsoft and samsung hadnt got any ideas
its because windows 8.1 has changed the usb stack and requires that all drivers be digitally signed and has an identifer that the bios can read
this means some old usb device didnt work unless they met condition already although new drivers became available for most things but for some reason samsung havent updated their usb drivers in years (May 5, 2011 is last officall release) so im guessing thats why it doesnt fully work in windows 8.1 and im sure the problem is because its not properly signed so the device fails to enumerate unless you do the plugging in another usb device
other old phones work fine like htc and new samsung phones also work fine so its properly just a strange issue with the way the galaxy y handles usb

unfortunatly thats the only solution iv found for windows 8.1 - if you restart the phone or remove the usb cable you have to go through the process again of unplugging cable plugging back in then plugging any other usb dongle in after - its the only way iv found for windows 8.1 to enumerate the device

Still no luck, it always showed doesnt recognized, even other pc and laptop (Win8.1, Win8, WinXp). I think its hardware problem

Hmm, seems hopeless for this matter
Will ask google for this classic problem or bring it service center.

is it possible to flash kdz file without usb?

My phone usb port doent respond, except to charge. Its definitely not the drivers on my computer, as even my usb on the go doesnt work. Anyhow....other than that, the phone operates fine. Is it possible to manually flash this file without using usb cable? And any idea whats wrong with my usb, i have a new usb board on the way, but i got a feeling that wont fix it.
