Liquid with usb problem

[Guest airmanfly!]

Guys, I tried to look into several sections and I apologize if that describe correspond to some other post, but I guarantee you that I have tried all the solutions described above.

In my practice, Liquid, with an A1 last bin Froyo, CM6.1 1.2 roggin and Malez recovery 6.1, no longer recognized by my pc. I could enter the recovery partition on the SD "toggle USB mass storage", acer tool and autoinstaller of the Malez recovery recognized the phone.

For a couple of days the phone seems to be isolated from the PC when I connect it says "USB device not recognized", Acer tool does not see it (tested with combinations of keys, removing the batt for 10 min, etc.) and also the autoinstaller Malez not identify the phone.

What should I do?

Thank you all.

edit: There is a way to flash. bin from recovery to restore the original cell and send it in for service?
