Hey, i had the same problem. I don't know how windows calls the options in the English version so i'll try translate the best i could.
You have to do a right click on "My Computer" then select "Manage" (the option has a checked yellow and blue shield). Enter "Storage" and Disks Management and here you have to find the mass storage, right click on it and choose "Change unit letter", select one and re-conect the device. I'm sure it will work for you

Questions go in the Q&A section

Same Prob

did you installed the tattoo's drivers? have you tried the usb connection software (must be set to usb storage)?
yes i did al of those things but it doesn't work i even did reinstal the drivers and htc sync
Check following path to set if you have already selected some thing by default
uncheck it.
Menu > Settings > Connect to PC > Select Ask me option
Then go to launcher and selected USB to PC
If it says Disk drive then select HTC Sync and Select Ask me option and click Done
when it prompts to choose quickly select disk drive and click OK (you have to be fast here other wise phone would go to htcsync)
If it goes to htc sync cancel and try to change again to sdcard/usbstorage and see if it prompts. or change again to htcsync and try again
I had bad experience with earlier donut builds where it is not easy to connect to PC
If you have already done this and not working then you could access sdcard via recovery
the last tip doesn't work for me neither???
does anyone knows a other solution so i can update my tattoo with htc sync?

Can you explain a bit more on what you did and what happened.
That would help people to understand what is happening.
By the way i have update my previous post with exact menu ( i had to go back to 1.6 rom for a while).
Can you also change you usb cable and see if it helps (if you can borrow from some one)
All the best
when i connect my phone i don't get the message from where to select diskdrive or htc sync i only get that message when i reboot my phone while it is conneced throug usb

I have possible answer

As rallapag (almost?!) said, i used to connect it to PC, then enter the app drawer and find that app with a logo showing a light blue screen, maybe called USB to PC. Enter it and select HTC sync.

Desire HD seen as 'UNKNOWN DEVICE' in Windows 7

Hello Everyone,
Unfortunately, in Windows 7 (32bit) the phone shows up as 'UNKNOWN DEVICE' in device manager. I have HTC Sync installed, Android SDK with USB drivers, I even hacked the inf file to add the hardware id of the Desire HD with no luck. Does anyone know if the hardware id on the Telus Desire HD is different than USB\VID_0BB4&PID_0CA2&MI_01?? I also flashed back to the original rom in case something got screwed up but no luck. Any help would be appreciated as I'm desperate.
Thanks in advance.
UPDATE:
Exchanged it at Telus and new one works fine on stock rom. As soon as I upgrade to CM7 I lose USB connectivity again.
I have removed HTC sync and only Android SDK with USB drivers, Device manager show "Android USB Device" and sub menu "My HTC"
hi.. i had a similar problem with my windows 7 pro (64 bit).. have you tried disabling "fast boot" and "usb debugging" enabled then restarting the phone?.. this is the only way i could get my windows to see the phone on the first install.. good luck and let us know how you get on.

I'm pretty sure I have tried that, but then again I have done so many things it's hard to confirm. I'll try that again to make sure and let everyone know.
Thanks.

Install the driver first.

Tried all suggestions listed repeatedly with no success. It doesn't even mount the sdcard in Windows or MAC OSX. My Dell Streak will at least mount the sdcard with no drivers installed.
Try with another computer, and select disk drive. It should not require any additional drivers, the phone is a plug & play device.

This is happening on my desktop and laptop.
Then there is something wrong with your phone. Are you using a custom ROM?

No, it's the original rom. The reason I want to connect it is that I 'want' to install a custom rom. Problem is the computer never recognizes the phone.
Anyone have any other suggestions, I'm desperate. Looking into getting it warrantied through Telus but but want to send it in if I don't have to. Don't want to wait who knows how long to get it back.

Samsung Galaxy S II USB Issue

Hi everyone,
Just got my Galaxy S II today but am having 2 issues with it, 1st, i dont know how to mount it in mass storage mode, everytime i connect it, my Win 7 x64 just tries to find drivers for MTP device but doesnt find any, I tried installed SGS 1 drivers.
My other issue is everytime i boot up the phone, the status bar crashes like 2 - 3 times, until it stops crashing and no longer appears, the message
"The application Status Bar (processcom.android.systemui) has stopped unexpectedly). Please try again"
I have tried restoring the phone to factory settings, however, this didn't fix it as after I installed a few safe apps (angry brids, google earth, well known apps) it happened again.
Thanks for your help.
Try to install Keis or try a different usb port/computer to see if that resolves issues. Have you done any modding or anything?

Had the exact same problem when I first got mine. Do a factory reset and format the internal memory aswel. I had my micro-sd card inserted aswel but it didn't need to be formatted. That was 3 days ago and I havn't had a problem since
Put it in development mode: settings, applications, development.
Then when you plug it in, an option will appear in the pull down menu bar, just select "connect usb".

Regarding your issues with the USB. My SGS2 by default seemed to have USB Debugging enabled under the application settings, this meant it always connects as Mass Storage on my machine. When I installed Kies to update my firmware I had to un-tick USB Debugging before it would load up in MTP mode for connection to Kies.
Hope this helps.

I have the latest Kies installed :/, I just tried a different USB Port and nothing changed. Nothing at all so far, all stock.

I just tried doing a factory reset, formated the internal memory and the micro sd, the problem was gone again until I activated usb debugging mode again through the settings, a strange problem as this means I can't access the phone in mass storage :/

Just tried this mate after factory resetting and formatting everything, this seems to be the cause for the crashing of the status bar as everything is fine until I try this

Guys its simple.....i was also facing this problem. just unchecked USB debugging mode....and try to connect again. Its Done.

driver problem

i don't know why but drivers for windows 7 doesn't work well with my milestone 2
if i try to connect my phone "as a memory", like a flash usb drive, windows try to install driver from windows update but fail and i can't copy files from/to my phone, like it's not connected
if i use "windows mode" (didn't remember the correct name ) it work but it is so slow to do everything
now i have cyanogenmod from endless7, perfect mod but without this "windows mode" so i can't connect my phone with my pc with windows, it's strange because RSD lite recognize my phone, so i don't know if the driver work or not
someone know the solution?
plug in your mobile, then right click on my computer > manage > device manager, there should be an MTP service that's got a yellow question mark. Right click on it, press driver update > search my computer for the driver, click on "let me choose from driver list" and there should be something like usb mass storage, click on it and click next. Can't describe it as it should be because I already did it a while ago Hope it helps, worked for me!
i love you, it work thanks
Same problem when connecting like Portal & Tools. Tip doesn't work (no usb mass storage driver). Using CyanogenMod 7.
Any suggestions?

You should enable Developer Options in settings and enable 'USB debugging' for that to happen.

Well
First you have to connect your device to pc and select the MTP option.
Then on your pc go to device manager and you will see unknown device option.
So right click on it and select update from the computer and select the directory
C:/program file (×86)/realtek/NICDRV_8169/
and down choose let me pick from a list ...
Option and select android then click on MTP usb driver and install.
That's it...
Thanks!! it worked well..!!

To solve mtp issue
Just make sure u are in none windows N version or ltsb
If u are in N version of Windows install Windows Media player
Package to add mtp protocol to windows
Maybe the media server service on your device is disabled

You don't need one
Your realtek driver in programfile 86 directory will do the job...
Comrades,
Just to clarify this is what worked for me - I pieced the info together from this thread...
http://en.miui.com/thread-858267-1-1.html
Several people hinted at the solution in the thread, but didn't specify exactly how to do it. Here is what worked for me - but this is Android and Windows so it could be some other random setting somewhere in your phone or PC.
I enabled developer options and debugging mode with the usual magic incantation.
I connected my phone and told Windows to open folder when it connects,
On the phone I pulled down the notification screen you will see at the bottom "Android System - USB charging device". You have to use your psychic powers to know that you need to tap this notification.
When you tap it you see "Tap for more options". so...tap for more options.
A new and magic dialogue box opens up that gives a bunch of options. Top of the list, and the default option is "Charge this device". But the second option - which was a winner for me - is "Transfer files". Tap that radio button (while whispering the word "abracadabra" under your breath) and there you go!!! The folder magically appears on my File Manager.
If you think of it like one of those 1980s text adventure games it's actually rather fun.
If you think of it any other way it's a freaking pain in the arse!!!
By the way, if it doesn't work you probably thought I was joking about whispering abracadabra...I wasn't!!
I assume this is a bug that you can't just tell the phone to default to file transfer???
Cheers,
SPuD
MIA1 and Windows 10 and MTP
