usb problem

Hey guyz, i have been facing a weird problem lately....my PC recognises my phone through USB only once.Once i mount USB i cannot mount it again i.e i dont get usb connected notification when i connect the second time.

sdcard visible only via cwm "mount usb storage"

Sorry for the title but I didnt know how could I describe it more precisely.
Problem is. I rooted gf`s htc explorer and I didnt have sd adapter so I tried to format micro sd via minitool partition wizard while it was inside phone connected via usb to pc.
After that I lost possibility to change usb mode from charging to file transfer since my card doesnt show up on pc/mobile/cwm anymore. EXCEPT "mount usb storage" in cwm. With that I see the card in pc, I can reformat it or transfer files. But I cant use it its not visible at all..only in that cwm mount usb storage.
I was browsing web/xda for like 2 hours and im quite desperate.
Any help how to make it visible again?
Its only unlocked-rooted-stock..was preparing it for link2sd.
thank a lot for a help

[Q] usb problem?

Hi,
When I connect my phone in usb mode I see my SD card on my computer but not the phone's internal storage (latest HiSuite is installed). The MTP mode does not show all my folders and files that's why I really need to see the phone in mass storage mode.
Also, whenever I connect my phone to the computer, USB debugging mode turns on even though I disable dev mode. I tried factory reset twice and install/uninstall HiSuite but it still does not work.
That would be awesome to have some help.
Thanks
Can you guys at least let me know if you are able to connect your phone's internal memory in mass storage mode?

MTP mode should display all folders/files in internal memory. However, same as you, sometimes, the computer does not show all. What i do is just disconnect, then reconnect. Oftentimes, it solves the problem. If not, then i both restart the computer and the phone, then it will be ok.

Hi !
Do you have the MTP drivers correctly installed for your device ?
Connect your device to a PC using the USB cable.
The device will automatically pop up as a USB computer connection. Tap Open the USB storage device.
If the USB computer connection does not pop up automatically, drag the Notification bar downward.
Choose the connected USB device and open USB storage. You will not be able to access the SD card in your device while the device is connected as USB storage. Set the SD card as USB mass storage to copy files between a PC and the SD card.
Cheers !
