How to use QCMA with USB without problems in Windows

So, I had two ways to back up my data from my PS Vita to PC and vice-versa: Sony’s CMA and the free and open-source QCMA.

I had at first tried QCMA, but since there was no UI option to change the language, had just uninstalled it and installed Sony’s CMA and was okay with it.

But then I thought it might be good for me to try QCMA once too. Besides, the “Backup Manager” is a really cool feature. Kudos to the dev for that!

However, while Sony’s CMA worked out of the box, QCMA gave problems, somewhere in the drivers. It would connect and then disconnect and so on. So I luckily found the proper page on the QCMA thread the /talk forums at wololo, so I read through those, and made QCMA work.

The problem lies with the drivers QCMA installs. It installs an old 2012 driver of libusb32. But that doesn’t sit well with the Vita. So here are the steps to get it up and running:

1. First up, remove Sony’s CMA if you have it installed. These two guys don’t seem to get along, from what I read.

2. Install QCMA by downloading the latest version from wololo.

3. Download zadig from here. This person makes awesome nifty software. Respect. Another of their creation I regularly use is rufus, which is pretty much the best image writer for thumb drives out there.  Be it windows or linux. I highly recommend that as well.

4. Plug in the PS Vita and then launch zadig.

5. Check if the “PS Vita Type B” is shown in the list.

6. If not, go to “Options” –> Check “List all devices”.

7. Once you see the PS Vita B, Right click on the arrow next to the big button, and select “Replace Driver”.

8. Now click “Replace Driver” aka the huge button, twiddle thumbs till it’s done.

9. Once this is done, start QCMA, and then plug the PS Vita back in.

10. It should detect the device properly and now you can copy it.

11. In case you’re on a lower firmware and the Vita asks you to update the system software, follow this guide after doing step 9.

Tips:

* If the Vita is not detected at all for some reason on the PC, it might be that something in the Vita side got stuck. So please restart the Vita and then try again. It worked for me.

On another note, for the PS+ list of June, there are a few titles announced today, but the PS+ site says the next announcement is on 8th June, so I’ll hold it off until that.

  1. Still not working, on PSV in CMA I hear the USB notification go off then on then when I hit connect via PC it says could not connect. PS Vita Type B in device mgr is driver ver 3.0.7.0

  2. i dont understand step 7, the opstion list is,libusb-win32 / winusb/usb serial/ libusbk
    wich what i should choose

  3. For those having an issue of the vita either not connecting to QCMA via USB or asking them to update, uninstall QCMA and reinstall it. And if you used the zadig app, pay attention to what type of usb driver you you use. If you used the libusbk, be sure to choose that option when qcma prompts you to choose a usb driver type in the beginning of the installation.
