OK, what Kit Kat ROMs have USB mass storage mode?
If a ROM does have it, exactly how/where is it enabled?

Either a ROM doesn't have it or if it does the dev hides it some place and requires digging through 100's of stupid pointless posts to maybe if you are lucky, find the answer.

I'm at the point with this USB mass storage B.S. that I'm ready to leave Android completely and get a flip phone. Whomever thought it was a good idea to remove it was an idiot and whomever signed off on it was even a bigger idiot.

MTP is absolutely terrible, completely half baked and totally unreliable.

Right now I just discovered that ChromeOS doesn't even support MTP... Google's OWN PRODUCT...

I'd like to know the answer as well.

I understand the frustrations but the problem with mass storage is that it surrenders all control of the internal storage to a PC not a problem when that's a different chip but on the n7 and most new smartphones its an emulated partition and giving over total control would mean that android cannot function at the same time. This was brought in to stop manufacturers using two separate chips giving you loads of "storage space" but very little application space. Its a work in progress and has many issues but its here to stay I don't think any ROMs will support USBMS as it not possible on a single chip without shutting down android.

LOL. In camera mode you have access to the "Pictures" folder and is readable by Windows and other OSes. All that needs to be done is duplicate the same process and direct it to a folder called "Storage" with full permissions for the folders contents. This essentially simulates USBMS. You can even redirect mounts to that folder so that apps see it as a storage area as well so things like map data and so on are put in the "Storage" folder.

I don't have the time to mess with this but it can be done and something almost exactly like this has been done before on almost every OS.

I imagine it can be done but it wouldn't be mass storage and would require apps to be compatible it may have been done on other systems but how much space should this storage folder be allocated because it would no longer be avalible to install apps. In camera mode android still retains control of the folder other os can read that folder but files must be copied off the device to be edited. It would be good if android could mount the SD card as mass storage.

No it would not technically be mass storage, thus the "simulated" comment. As far as other OSes, it's already been done to a point on android already via the simulated partition that's already in use. This has also bee done using third party apps to mount folders as virtual drives.

App compatibility, if the folder is used as mount point then it is transparent to the OS and the apps. This has been done for some time now using third party apps.

The folder size could have the same limitations that the storage area has already been limited to. If coded so that it is part of the boot process then everything outside of system apps would only see the virtual area. Kind of like what's being done right now.

Dual mount. This has been used with much success and allows for PC and Android access to the same storage area at the same time.
