[Q] USB Mass Storage Issue

Hello everyone, I have been using this forum for a while now, but havent really posted anything much as I have always found answers to any questions through searching the threads, however, I am unable to find a solution to a problem I have just recently encountered and was hoping someone out there may be able to shed some light on it.
I am using an unbranded handset running JPO which has been performing superbly until today, however, when I connect the phone via USB to my PC and select mass storage the computer does not seem to recognise the phone is plugged in. The strange thing is it worked perfectly before and the only changes I have made since was upgrading the micro SD card to a 16 gig one. I try unmounting the external card and even removing it completely to no avail. I have tried the phone on 3 PCs now, even my Linux PC does not recognise it.
I have rebooted the phone, tried connecting selecting Kies mode instead of mass storage, all to no avail. As soon as I connect the USB to the computer, the phone recognises the connection and asks what I want to do, I select mass storage, then I get the option to mount via the little green android, which turns orange stating it is connected, but the phone just does not show on the pc.
Any ideas would be most welcome, I don’t really want to have to format the internal memory but I think I may have to.
Many thanks in advance.
Additional:
I seem to remember on Eclair that I was able to unmount the internal sd card in the settings menu, however, with froyo, I only have the option to unmount the extrernal sd card. Would someone running JMO be good enough to check and see if they have the otion to unmount the internal sd?
Right, I seemed to have found the problem, so for anyone else who has a similar experience, it was the USB lead. SGS working as it should agian, phew..

[Q] Very slow USB transfer speed after Gingerbread update?

Hello!
I must ask it for you, as simply could not solve the problem for some weeks...
Im not sure in it, but from aprox. my Gingerbread update (first day when JPQ announced here at XDA... long time ago, just had no time for care about my problem...), the USB transfer speed dropped to aprox. 3-4M/s from 8-10M/s as write speed. With this rate I simply could not use my Tab for movie player, and dont know what is the problem.
I tried to change my Sam's USB driver from SuperOneClick boundle to the latest Kies version, but not helped (I thought maybe the SPOC driver is wrong, but not...) I tried it on 3 different computer, with driver in the latest Kies but on all I have this problem. What Im sure that before GB update my transfer speed was aprox more then 2 times faster, for write on the device... Im not sure that the problem is about GB update, but sure that before it was fast, and after become slow...
Could anybody help me? Maybe any tip what soft could make this problem, before I try a factory reset?...
Lot of thanks for it...

You are activating USB UMS over USB debugging deactivate USB debugging and activate Mass Storage in USB connectivity and you should get your speeds back.

Thanks for the tip I was glad to hear it, but sadly it not helped on me. I used USB debugging on all my Android devices always and was never any speed problem, but (now) I tried to switch it off, and just use normal mass storage connection. My transfer speed in this case still 3-4M what is horrible slow...
Any other opinion, tip on my problem?

[Q] MTP, PTP, USB Mass Storage

What is the difference between MTP and PTP on the TouchPad with CM9?
Is there a Mass Storage mode available? (MTP and PTP don't mount the tablet as an USB storage device).
Thank you!

Providing you get MTP to work it does have advantages over a pure USB disk mount which is probably why it isn't in ICS as standard.
MTP is the closest to Mass Storage mode at the moment, until they can make it work with ICS. From what I can tell, it's a widespread issue with many of the ICS Rom's out there.
Thank you both for replying. It seems MTP makes more sense than USB mass storage and is safer too.
Actually, for moving files around I found out wifi solutions like AirDroid are convenient and I don't have to plug in the cable.

Yes. Wifi connections avoid the need to plug cable in much. ES File Explorer, which is a very good file manager, can also see network shares on PCs over the wifi network avoiding the need for a separate app.
I still do use cable connection when transferring large files like Nandroid backupsas it is faster.
Make sure you use a USB2 port!
I kept having issues copying files to both my Galaxy Nexus and Touchpad until I realized I was using a v1 port. Swapped some cables around and it's working great.
I have tried ES File Explorer and it is slower than AirDroid when transferring larger files. On the other hand, it is more convenient because you can manage the transfers from the tablet (on AirDroid you do all stuff on the PC).

[Q] Disable USB auto-mount?

Hi,
Straight to the point: Is there a way to disable auto-mount of SD card in MSC mode (or SD + Internal memory in MTP mode) while plugging the USB cable to the computer?
In many situation I'd like just to connect to the PC for charging, not sharing all the data with PC users. Also, disconnecting before unplugging can be bothering. I am even considering installing an app that would allow to manage this.
I've searched for similar threads in other mobiles sections, but either there is an built-in option for that in their firmwares or the question remains not answered. How does it look with Xperia SP? I'm talking about Stock 4.1.2 12.0.A.2.254, rooted. Maybe the USB Connectivity function could be somehow modded?
Regards
