Ok, so I have a HTC EVO 4G and it's currently rooted running a MikRom. Recently, for some reason, when I plug my phone to a Mac or a Windows computer it does not recognize the phone in USB Mode. Specifically on my windows pc, I get a
"USB Device not recognized One of the usb devices attached has malfuntioned etc.. and I went through the process of trying to install the driver but nothing
I have also unmounted the card in settings and mounted it back and still nothing.. What I was going to do was completely erase my SD Card but will that erase my Root however?
It will not erase root.

Think about it like this; can you take your SD card out ans have the phone run perfectly fine? Then you can wipe it

Very True, Do you think that reformatting my SD Card will possibly fix the issue of it not mounting on my computer

It's possible. However, before you do that, take the card out ant put directly into a card reader for a computer. This will let you know if the card is bad, or maybe the phone's reader is bad. If the card is bad, you can try error checking it in Windows, and maybe salvage the data on the card.
But if that doesn't work, try re-formatting it. It may help, it may not. If not, new 8gb cards are only a few bucks now.
Ok I have one at home Ill try

It very well could be your USB. Use an adapter as posted, then try another USB.

SD card won't be read when phone is on. When device is in recovery, I can USB toggle and see everything on my SD card. It's only when I try connecting through USB when on (CM6.1 or Myn TwoPointTwo) is when nothing happens (Myn) or the phone freezes and reboots (CM6.1).
I had my phone plugged in through USB while on CM6.1 RC2 and dropping in the new CM6.1 file into my phone when I forgot to eject and went straight into recovery. Now I can't install anything or mount my SD card. I can use ASTRO or a file manager app to view everything though.
As for nandroid, I deleted all my pre-USB **** up backups and only have the USB **** up RC2 backup. So that won't help. I'm guessing the device is still thinking it's plugged in because of my mistake. Any way to fix this?
I have noticed this as well lately under both Sense and AOSP roms. I can't mount my SDCARD from USB while the rom is running - only in recovery.
Odd. Wonder what is causing this?
I was talking to Shift and we came to the conclusion that my SD card is probably corrupt after shutting down while still mounted to my computer. I just extracted the folders that are important to me (pictures, Titanium Backup, etc) and will transfer them over to a new SD card once I buy one.
If anyone knows any way this might be fixed, I would appreciate it
Did you already try reformatting the card?

i had the same issue with my 16gb card.
I couldnt get it to read in the computer either unless I put it in the full sized SD adapter and put the "lock" switch on.
Needless to say, i couldnt do anything with it and ended up sending it back for a replacement.

I was hoping to exhaust all options before coming across this, but as I have nothing else to try I'm going to just format it. Hopefully I can format through recovery or something because it doesn't even let me unmount my SD card from Settings options.

Yeah, I figure I'll try my last option of formatting and see if it works. Here's to hoping! Lol.
FIXED
Issue has been corrected by formatting SD card. Thanks for the replies :]
I am a newbie to rooting and trying different roms. Today after trying different roms, my phone no longer identifies the sd card. I have tried almost everything but I am unsuccessful. Any help will be grateful thanks.

What rom were you on when the problem started? Do you have a card reader that you could put the sd card into, and then into your computer? Does the computer recognize the card? I would see if you can format the card with your computer, and then put the card back in the phone, and see if that helps. Just keep in mind that formatting the card will completely wipe it, so if you have any important stuff that you need saved, I'd copy it to your computer before formatting it.
Did you try just taking the card out of the phone, then putting it back in? Does the computer see the phone itself when you plug it in to the computer? If so, can you view the card from the computer when you select "disk drive"?
Dont have a card reader and I was using Mikfroyo 4.6. When I flashed back to the original rom that I have been using for the past couple of days it no longer recognizing the sd card

Strange. So the phone doesn't recognize it, nor does the computer when you plug it in via USB, correct? Do you get a green charging led when it's plugged in to the computer? Do you happen to have another phone that uses an sd card, to put your card into the other phone? If not, and you're unable to format the card using the phone, then I'd try to get a card reader. Either borrow one from a friend, or buy one. They're usually pretty cheap. If neither of those options are viable, perhaps see if you could try another sd card in your phone for a sec, if you have access to one. See the phone reads a different card. Hopefully you'll be able to try one of those options. There is a thread laying around here somewhere, by Calkulin, and it has instructions on how to fix broken sd card and / or usb port. I'll have to look for it, but I know it's around here somewhere. You may want to search for that thread.
i will look for the thread..I reset my phone but not back to stock and still unable to read the sd card
Thought I would ask first... my SD card will not mount on my phone. Data seems to still be there but I have a notification saying "sdcard is blank or has unsupported filesystem." Tried to format but the card wont mount on the device. I've tried formatting in the android os and in recovery with errors. Does this mean the SD card is toast? Any help is appreciated. I'd hate to lose all of the data. Thanks.

At work right now and our computers are on lockdown, no external devices can be read. If I can access what should I do? When I tried repartitioning in recovery it said it could not mount dev/block/mm? ?? Or something like that, basically gave me an error. Any advice? Im about to just buy a new card.

You might just need to reformat the card. Sometimes the cards get corrupted. You might even still be able to access and backup the content on the card if a PC will read it. If you have WIndows 7, it might even offer to repair errors on the card. That could also get it working. I'd say reformatting it is a good idea either way.
i just had similar error... try removing and reinserting card. if that doesnt do it reboot into recovery and depending on the recovery you are using go in to mounts and try selecting "mount sd card" that last one fixed my issue.

I ended up just buying a replacement 8GB class 10 card (wanted a higher class card anyways, this gave me an excuse to buy one ). I was able to retrieve the contents of the SD card by mounting it in my computer (vista 32). I didn't try reloading it into my Evo cause now I don't have a need for it. Thanks for the responses though, glad that you guys are here and willing to help. :thumbup::thumbup:
Sent from my Modded Evo... It's easier this way.
Greetings XDA,
I would love help with my current situation. I am in the military and really need my phone working so my soldiers can contact me ^^;.
I have an HTC Evo, the older (original) version, and followed the steps here:
http: // htcevohacks <dot> com/htc-evo-hacks/root-for-htc-evo-4g-gingerbread-is-here/
It seemed to work just fine, and so I connected my phone to my computer to transfer some files. However, after about a minute, the my computer didn't recognize that my phone was connected anymore and I didn't even have the option for "disk drive" on my drop down list. Apparently, my SD card was unmounting itself. After rebooting and trying again about a dozen times, I decided to bypass the phone/usb deal and connect the sd card directly thought an adaptor. My computer recognized it and opened the drive, but once I tried to delete or move any file, the drive would dismount.
Becoming fustrated, I decided to try and wipe the SD card/format it, but because my phone won't recognize it and it dismounts itself from my computer, I can't do either.
Now my phone only boots into the bootloader and doesn't recognize the SD card at all.
I thank you for taking the time to read my post, and appreciate any help you can provide.
I would try swapping in another sd card

I don't currently have another SD card, nor do I really want to spend money on another one; if I can avoid it.
I've tried formatting the SD card several different ways:
Through basic windows means (Right Click > Format)
Through CMD Prompt
Through Admin Tools - Comp Mgmnt - Disk Mgmnt
Through 3rd party programs, etc
However, whenever I try to move a file to the sd card, move something out of, delete, format, or any other type of specific access, my computer can then no longer recognize it.
Is there any way for me to get my phone past bootloader, without the sd card? I've tried resetting all user data in recovery, but it seems that no matter what I do, I can't get past the bootloader.
Is there anyone out there with a solution?
Perhaps there are other details I can provide, just inquire.
So you can get into recovery? Have you tried formating the sd card with recovery?

What happens when you try to mount sd card in recovery? All in all it may be a bad sd card. And you might have to get a new one. Or if you got a friend that has a spare one you can use.

Thank you for your prompt replies.
Whenever I try to mount/access my sd card on the phone, it simply doesn't find it. I am using the same 8gb sd card that came with the phone, and I've had the phone since day 1 release.
The more and more I try to fix or find a solution to this problem, the more frustrated I am getting; and the more it is seemingly looking hopeless =/.
Over the weekend my phone has decided to not read my sd card anymore. I copied the whole card to my external drive and formatted it via the computer twice, I booted the phone back up and everything on my card was still there. I used the option in my rom (ILWT) to erase my memory card, no luck. I then formatted the card via cmd prompt today which didn't work, and then my last shot in the dark was to reformat the card via 4EXT recovery. My phone still gives me the "insert sd card" when I take a photo and all my of files are still on it. Anyone have an idea of what happened?
the sd card slot probably is bad if it won't work in recovery or a rom, could be the small cable that connects it or the tray it self. about 10~15 on ebay and a 10 min fix

Good call, will investigate.
Have you tried the card without the phone? In a pc reader or another device.

Yup, card still has everything on it.
It seems more like a broken SD card to me. Have you tried another one?
You can also try some low level formatting tool like HDD Low Level Format Tool (from hddguru.com).

Have you attempted to copy off everything on the card, and then doing a full format of it on the computer (including maybe low level formating).
IF that still doesn't work, try another SD card, and if that doesn't work, I suspect the slot itself is bad.
