yeah just had this headache of a problem. I was making the situation much more complicated then really needed to be. Long story short, i have about a billion micro usb cables laying around the house. What i didnt know, was, that not all cables are data capable. So when you plug it into the computer, it only charges, instead of giving the option of data transfer. I dont know if this helps you, but i hope so!

You can try a few things.
1) Try another cable
2) Try another computer
- i noticed sometimes windows take a few more seconds to recognise the mass storage
3) My wife's Optimus Black is unable to connect via USB, because it was rooted. If yours is rooted, perhaps you might want to un-root the phone and try.

USB Question

I just did the Gingerbread update 2 days ago, but this just started tonight..
I used the USB cable that came with the phone (for the charger) and plugged it into my computer to move some pictures from my phone to computer. This is the way I've always done it. For some reason, my computer wasn't recognizing my phone was plugged in even when the phone was set on Mass Storage. I unplugged and replugged a few times but to no avail.
And now, when I plug my phone into the USB cable while it's connected to the charger, on a wall outlet, it recognizes it like it's plugged into a computer and asks me if I want to transfer files and turn on Mass Storage.
It never used to do that before when on the wall, only when in the computer.
How do I fix this? Any suggestions? I also noticed my dad's Mesmerize does it also while on a wall charger, rather than just charge.
Any help is appreciated.
UPDATE
I just unmounted my SD card and took it out of the phone. Then I plugged the phone into both the computer and the wall via the same USB cord, and it connects just like it used to when I would plug it into the wall. No choice for mass storage, or to transfer/move files. So obviously it's something with the SD card?
I'm sure you guys already knew that, but just in case.

I also formatted my mass storage (SD card) thinking that would help.. it did not.

80+ views and nobody?

You are not alone
I have experienced the same problem ever since I updated my mesmerize to 2.3.4

I also noticed it doesn't hold a charge as well now that it recognizes everything like it's a computer. Charge now lasts about 60% as long as it used to.

NObody has an answer?

[Q] Two questions about USB ports

First up, Is there a hack or mod or something that would allow me to mount my android phone storage? I was shocked and kind of disappointed that it didn't work when I wanted to dub my mp3s onto my tf. Thumb drives and even my external 1TB hard drive work, so why not a phone?
Second, does anyone know what amperage the usb ports are rated at? Just out of curiosity.
Edit: The ports in the dock. Just so there's no confusion.

While I dont have any facts, Id be somewhat surprised if the USB ports were rated at more than the standard 500mA.
If they are rated more Id be happy though *starts planning on ripping apart a self-powered usb-hub*

USB ports always work at 5V and max 500mA
Using the full 500mA will drain your battery in no-time.
Why your phone won't connect, no idea.

Mystery solved!
Settings->Storage->Mount external storage
Every other storage device I plugged in just mounted automagically, so I didn't even think to check there

Super Slow USB Transfer Speeds

Has anyone noticed the super slow file transfer speeds one this phone? I just tried to copy a movie over to the phone that is about a gigabyte in size and on my other phones it would usually take a few minutes at most but this phone has been saying "calculating" for several minutes now without any data transfer happening yet.
I have the phone on disk drive mode so I would have thought this wouldn't be doing anything weird like converting the video file on the fly during transfer or anything. It should simply be copying the file over but it doesn't look like it's happening.
This should be a simple feature but it's not working for me at all.

Works fine for me. Much faster data transfers than my DHD.
Of course, I've been moving files via a Mac, maybe there's an issue with Windows + OneX file transfers? Hopefully someone else can confirm.

Speeds have been average for me when compared to the E4GT. These 2 phone are still a faster transfer then my old nexus S. I would say the speed to transfer is roughly 5 min for a 700 mb film. I don't know if thats fast or slow really though.

About 12 ish minutes for 6gb of music. Not bad at all

might want to try a usb port on the back of your computer, or a different cable.

HTC USB Cable
Are you guys reporting fast file transfers (or at least average speed file transfers) using the usb cable that came with the phone or another micro usb cable? This morning when I tried to copy that movie file I was using the micro usb cable that came with my Moto phone (which I thought would be fully compatible) but got those really slow speeds which seemed like it wasn't transferring at all.
My HTC One X micro usb cable was left at the office so I didn't have it with me at the house so I couldn't try it. Now I am at work I guess I can try it with another large file but do not have the movie file I was trying to copy this morning with me.

I notice a change iin file transfer times on my HTC Sensation since upgrading to ICS.
I even tried using TeraCopy, but the time are just as abysmally slow - it definitely wasn't this slow before.
Am thinking to try taking the SD out of the phone and copying directly to that to see if there is any difference.

Yep, that worked, copied to the direct to the card via a card reader very quickly.
I did however choose to fix the bad sectors when that dialog came up, not sure if that helped.

Guessing your posting in the wrong forum since we can not remove our sd cards from the HTC one x

You're right, I thought it was a general issue, and didn't know the One couldn't do that.

That was happening to me and was the usb cable!!!!! lol

when i use total commander under windows it reports between 20 and 30 Mb/s
That is way faster then i had using my Samsung microsd in my card reader

Why the cable could slow down the transfer?
I just bought two of this cables: http://dx.com/p/designer-s-flexible-usb-charging-data-cable-for-htc-174cm-length-73860
And with one of these I sometimes get connection to the computer and with the other connects... but really slow, les than 1Mbit/sec.
Could it be a bad soldering? Could it be that the cable is flat? Could it be that some endpoint is not connected inside the cable?
The original HTC cable is flat: http://www.htcaccessorystore.com/uk/p_htc_item.aspx?i=196200&phone=196001
I must add that if I use the OEM microUSB-USB cable works perfect.

USB transfer speed?

I noticed the 3a only have USB 2.0, not 3.0. This is causing me to have a reconsideration on this phone because I take lots of photos and transfer files from and to the phone everyday.
Just want to know the experience for those who typically transfer files between their phone and computer. Does it feel too long especially compared to your other phones with USB 3.0.

Without using any tools I ran a few tests. I copied a 3.2 GB MP4 file from an SSD to the Pixel 3a twice. I used a USB C to USB 3.0 cord. It took 1 minute and 11 seconds. I then copied the same file using a USB C to USB C cord. It still took 1 minuted and 11 seconds.
That's roughly 45 megabytes per second.

I just use my network drive and transfer everything over WiFi as ac wireless is nice and fast.
