same for me , i can hot swap usb mouse / xbox360 controller many times , 1'st time I connect a usb flash drive I can see contents it in astro , disconnect & re-connect no contents untill I restart ???
does tiamat 1.4.2 support hotswapping of usb drives ??

Lots of these topics floating around. All looks the same after u connect a file/drive u have to reboot. Kinda sucks. Mice/controllers/keyboard not effected. I wish a dev would pop in and just say yes u have to reboot all the time or there can be a solution or something.

Are you sure you got an host cable? Do any other devices work with it? Like a mouse or controller.

Drives over OTG are indeed hotswapable. I do it all the time.

first let me say thankyou brd , every mod I have done has come from your posts.
I am quite diligent and read everything I can before I flash or mod and even post in the forum , but , is there something I could have missed that causes me problems hotswapping usb drives , I am at a loss . .
thanks

Just an update on the need to reboot to access usbOTG. I got my official USB adapter today from Motorola. I have hot swapped 5 different drivers and sticks and it reads every time. Even my 250gb WD portable hard drive.

@ hoola
so did you have a grey otg cable and got the same results as others and I have got , and now you have the official host cable as is well ? am I correct ?
also exactly what are you running , and the route you took to get there , i.e. my route was
uk 3.01 , one click, tiamat as they came out untill 1.4.0 > BRD's cwm flashed 3.1 update > tiamat 1.6ghz with usbmass storage (thats not working too well for me)
thanks

I had a grey/clear generic cAble. I rooted using another method on another site then *redid* it using brd method . I just tried using the generic cAble and it does not read after first swap until reboot. With moto cable it sees all devices . I switched out like 20 times in a row with 5 or so devices (USB , external, USB card reader, few sticks) and it reads every time.

[Q] Trouble transfering files to the Xoom WiFi

I'm trying to transfer some mkv's over to the Xoom into the Movies folder. I'd like to try to play them in RockPlayer. However when I try to transfer the files, the prompt pops up saying the Xoom might not be able to play this type of file and do I want to continue. I hit continue and the transfer pops up but it never appears to transfer. Anyone have an issues like this?
Edit: I just tried transfering simple photo's over to the Xoom, I can't even transfer those. After waiting for the file to transfer it eventually pops up saying the device is either disconnected or unreadable.
There is a difference with WiFi vs.3G xoom. I had the Verizon version and returned it. purchased the wifi version today and noticed immediately that my app NBA game time doesn't work but it did on the Verizon version. Something is up but I can't say what was changed. GPS works but the app just closes when it is launched. So, stuck with watching the laker game on EVO.
Do you have the correct drivers installed?

yes, I made sure to reinstall them directly from motorolas website.
Well I think the problem was that I just used my HTC Micro USB cable since it was already plugged into the computer to transfer files to the Xoom. I started to think about it and since the HTC cable could be used to charge my EVO, perhaps it was the problem. I switched cables and it is now working without a hitch.
There is absolutely something odd and unique about the USB cable that comes with the 3G version. I can NOT use the one that came with my Nexus. Grrr.

Ugh. this is no better than having a proprietary cable...
I used my micro usb cable for my samsung captivate and it worked fine transferring files with the xoom.
I bought a 6ft Micro USB off of Monoprice and it works with my EVO and WiFi Xoom just fine.
I can mount the xoom wifi on my pc at work but can't mount it on my macbook pro. I have tried three different cables but no go. Is there something different for the mac other than plugging in?
You may have to fiddle with your settings in your system control panel... would be my guess for getting it working on a MacBook.
I used the micro usb from my thunderbolt and it works fine on my mac to xoom.. for mac, make sure you have the android file transfer software installed coz it wont recognize the xoom as an external drive.

I was having the same problem. I used the cable that came with the Xoom Wifi and everything is working now. Now i just have to make sure i don't get this cable mixed up with my other moto cables.
hi,
I can't download "android file transfer" from android.com in my country (weird google policy!). anyone knows an alternative or mirror link for download? I tried using VPN but somehow it detects I'm connecting from the same region!
thanks
I'm not really sure what that warning relates to. I can say that mkv playback on the zoom is pretty bad even using the handbrake profile that was floating around that creates flawless HD mp4s. With the same source I got audio outs within a few seconds on the mkvs and no problems with the mp4s. Avi files that had warnings played just fine.

Unable to mount USB to play MP3's in car radio

this is probably a dumb question, but i need to ask.
i'm not able to play MP3's via USB on my car radio. the phone says USB is mounted, but the radio won't recognize it. i am able to do this same method without any issues with my MyTouch 4G and my car radio will play the MP3's from the phone.
i'm guessing my problem is because both the internal and SD cards are trying to mount and my radio doesn't know what to do...? i know with the MyTouch 4G, it only mounted the SD card since there was no internal drive to even mount.
i'm tried this on MIUI 1.8.12, Trigger, Weapon G2x, and EaglesBlood 2.3.5, but have not had any success.
is there any way around this?
That's weird, I'm having the opposite problem, the car knows that there's something on the USB but the phone just ignores it, never shows the notification for me to mount the USB as storage.
My iPhone worked perfectly.
The problem is drivers.. sorry guys but even with cm7 installed in order to mount the SD card and internal storage to the PC u have to have the LG drivers installed.. HTC doesn't require proprietary drivers for theirs.. it sucks cause I used to do the same thing.. now I use aux input from the headphone Jack.. doesn't sound nearly as good as letting my head unit read the mp3s..

So what you're saying is that I would have to install LG drivers to my car stereo, right? If that would be even possible.
That would be the only solution I know of.. but I don't think its possible..

That's ridiculous. So basically I paid more in my brand new car in order to have wheel-mounted controls and MP3 folder navigation for nothing. Ugh!!!
I just want to update this post because I think I found a solution, and would like to help if anybody out there is experiencing the same problem as I am.
I was initially using 2.3.5, and due to the lack of A2DP I downgraded to 2.3.3 yesterday. It seems that in 2.3.5 the checkbox "use as mass storage only" was taken off from the "Storage" section under "Settings". As soon as it was available on my phone and I checked that, the phone recognized the connection with the car and asked me to mount the USB drive, and voilĂ , my car started playing my MP3s.
I always thought it was weird that everybody talked about this menu option but my phone didn't have it, and nobody mentioned that it was taken away.
Hmm guess I'll have to try that also..

Not for nothing...just buy yourself a cheap USB thumb drive (8, 16GB, whatever) and fill that baby up! Attach to car stereo, and you're done.
Way easier than getting your phone out and hooking it up every time you get in the car anyway...

Scratch that. It worked once, never again. The USB notification shows up but the car says "error".
I'm done with this crap.
I came across this thread while trying figure out the same thing - connecting g2x on my car's usb in. I am on ICS (CM9), but everytime I try to connect in UMS mode, my phone stops detecting usb altogether. If I choose MTP, stereo detects usb, but doesn't play anything.
Is this a deadend or do you guys have a way around it which is being discussed elsewhere?

USB Storage can't be turned on

So I got an incident with my phone, if you wanna now about it, its at my sig, but the thing is that I dunno why or how, sometimes my computer does recognizes my phone and display the Turn on USB storage option at the notification bar, but each time I try to turn it on it just wont work. Attached is a logcat whenI try to enable it, maybe someone could tell me why it wont work.
What rom are you running for those off that are on the xda application?

Normally I got two nandroids a GB based one and an ICS based one, right now Im using both Eagle's Blood 2.3.7 v2.8 and ICS 4.0.3 Build 1. But I had this problem since... always. I'm a flashaholic so i have tested actually every rom from stock 2.2.2 to beta 4.0.3... I even have a nandroid of my original ROM (the one that came with it when y bought it and rooted it) and not even there works. The only clue i have right now is that only if I disable USB debugging it will randomly connect.
This may sound dumb but have you tried a different usb cable? I had the same problem and tried my girls and my phone was able to connect each and every time. another thing I noticed with my phone is that it sometimes won't connect using windows 7...xp no problem but 7 it plays hard to get.

Holy Mother of God! I did it!

Then all I had to do was NVFlash again, restore the stock 2.2.2 Nandroid i had somewhere and play a bit with the USB mount/debbug options, flashed both storages (using gparted for the microSD) and it works! Now have to restore everything to my SD and reflash latest cm7...

Did you ever figure this out? Sounds like your having the same problem that i am.
I've tried at least 6 different cables, home PC, work PC, laptop and a co-worker's PC that didn't have anything vmware installed (had a hunch that vmware usb drivers were the cause). Oh, all the computers were win7x64.
I've only rooted my phone and upgraded to 2.3.3 so nothing crazy going on there and it's worked for months since i did both of those.
I have a feeling that this may have been a recent windows update, but no clue when or which one because i haven't really cared that it didn't work. If i had to guess i'd say mine stopped working about 3 months ago... again, hard to remember.

Make sure usb debugging is turned off.
Plug in the phone, enable usb storage.
Right click on the phone drives in the explorer and click on eject.
Turn off usb storage.
Unplug and plug in again.
Enable usb storage.
Drives should work now.
This did it for me. Since then if I remember to eject before unplug I haven't seen any issues.

Thanks for the reply, I'll give that a shot.
Curious though, when yours was having problems, did windows detect anything? For instance, when I plugged mine into my co-workers pc there are zero pop ups about new hardware detected.

I had the same problem. Dirt in the mini-USB port can cause that problem.
Take a can of compressed air and blow it into the mini-USB port (blowing with your mouth isn't enough). Also, take a close look at the port with a magnifying glass and look for any dirt or discoloration in there.
Do the same with your cable.
Not working after install RemICS 1.3.2

Hi, this problem occur to me after I've installed RemICS 1.3.2 ROM (CM9 based), I did follow the installation steps from beginning, when the problem occur, I did re-flash the same ROM several times, but this problem still unsolved.
I did try all recommendations (blow out dirt, disable usb debugging etc) but still not success.
This ROM should able to detect USB when phone connected with PC, but somehow I don't know why. Any experts recommendation?

Ok, I just found the problem. I can hear now the tone of PC detected USB when plugged-in, and I update the driver. then Voila!!
Thanks All..

Hey, just thought I'd register an account because I stumbled upon this thread because I had the same issue verbatim and I managed to get it working.
I ended up using the USB 3.0 ports on my desktop and suddenly it picks up my g2x without fail everytime. With that said, I'm lead to believe that perhaps its an issue of power. Maybe the USB 2.0 ports you're using simply aren't providing enough power. Not sure what its worth or if my issue was something unrelated but maybe that bit of information is something to work with. =)
Found another solution that fixed the problem for me.
If you are using Windows XP, log on as an Administrator and open Device Manager
Select View > Show Hidden Devices
Scroll down to Storage Volumes, and expand
Right-click on each entry and select Update Driver.
This fixed the problem for me!

[Q] Computer Doesn't Recognize Phone but it's charging

So I want to take the pictures off my phone and add some files to the sd card from my computer on my new S3.
I have installed the drivers (but not Kies) and when I plug in my phone, the phone beeps and starts charging but it doesn't show up on My Computer. On my old Rezound, I would get an option to charge only or data but it's not showing up on the S3.
Is there anything special I have to install for my computer to recognize the phone except for the drivers?
changed the cable, from my old one to the Samsung one and it now works

Does your kernel support USB fast charge? If so, it may be enabled.

If it's not the fast charging issue as mentioned above, its most likely your base OS. I was having mounting issues as well, especially on my Mac. The latest K1 JB leak fixed it. I believe the ICS HE release also fixes it.

[Q] [OTG] problem with card reader and gopro

hi to all, I have a Nexus 5 with the CM11 installed. I have an otg adapter, it works with normal pen drives but I have problems with those two things:
1)a memory card reader, when I connect it to the phone I see "preparing usb storage" for a couple of seconds and Ican even see the card contens, but after hat I get "usb drive removed unexpectly" and I can't see anything anymore. the reader works perfectly on pc, tvs and any other device I tried.
2)a gopro hero2 camera, I sherched on the internet and found out that it should work. I turn it on and than connect it to the phone, the camera display shows "usb mode" for less than a second and then it turns off
what can I do? It's an OTG, phone or devices problem?
thanks in advance

nope, I flashed CM after two days of stock android, I don't even have the OTG a that time....in a couple of days I should be able to try another OTG at least I can be sure that the problem isn't there
I tried with my Galaxy Tab II (stock rom). the GoPro works but the card reader doesn't (maybe 'cause it's very cheap). I think my Nexus do not provide enough power through the usb port. I think I'll ask on the official CM11 forum if this is a known bug or somenthing else.
PS I've another small question: my phone notified me about a new CM release, Will the OTA updater wipe my phone?
