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] USB Connection Won't Work

I can't seem to anyone else who has this problem. My TF700 is working great. However, today I decided to bite the bullet and install CleanRom. After unlocking, I realized that my computer can no longer see the tablet via USB. It is not an unrecognized device, just nothing happens when I plug it in.
I have tried two different cables on 3 computers, so I believe the problem is with the tablet itself. It charges just fine and when I plug the cable into the computer or unplug, the screen comes on (just like when you plug in the charger), so something is getting recognized.
I don't see any physical damage to the port, it looks fine.
Anyone else ever seen this?
Thanks,
Chris

So it was working previously?

It was, not sure how long ago though. I know it was when I first got it. I'm guessing it is a hardware problem, but not sure what to do about it. I honesly don't care all that much about it, but I would love to get TWRP on it so I can flash roms. I haven't seen a way to get TWRP on it without the USB or GooManager, but I can't run GooManager because I don't have root yet.
Still trying to search to see if there is a way to get root without USB, but I haven't found anything....

Chris,
See if downloading and installing PC Suite from Asus helps.
That might get the drivers working again.
Are your PCs win7?

Just a thought. I am not running clean rom but when u connect to ur pc try going to settings, storage, and and hit the 3 little dots on the top right. It should show some usb connection tab.

Thanks, I'll try the software install, but since the computer doesn't even tell me I have an urecognized device (nothing in device manager), I'm not sure that it is. I also already rolled back to stock ICS and also tried the storage settings to no avail.
I unfortunately think I have a hardware problem. I guess I'm stuck at trying to get it repaired, or just live without the USB connection....which I guess ultimately means no customizations. I can still flash back to the stock Jelly Bean using the factory bootloader and rom from the Asus site, so I may have to live with that.

Could be the cable. Sadly, replacing it is ridiculously hard.

I wish it were. I have a second charger/cable and already tried both cables on different PCs. Uggh.

Connect the tablet to a PC running Linux and run lsusb to see if the tablet is recognized (the vendor ID is 0B05) - just to sidestep any possible Windows driver issues.

First question is no, not that I know of. No one has investigated if it works or not on this device. But I would think it would. They can use the same identical keyboard.
Second question is yes you can, but you will have to use USB debugging (ADB) to do it. Then you can push files from your device to your phone. They can't just connect together like one was a computer and the other was a media device or attached storage.
If your phone can accept a micro flash card, you could transfer it that way too.

[Q] [SOLVED] tab2 7", mouse via USB OTG, what rom/kernel?

Hello, I had a tab2 7" more than a year ago. I remember using mouse and other usb otg devices on it.
Then I sold it. I can't remember what rom was on it.
I remember usb otg notifications worked, telling something like "mouse is connected" etc
Now I got another one, it has custom rom installed but usb otg isn't working and was trying to figure out the new ROMs.
I tried lots of latest roms with no luck.
Kitkat ones are great, run smooth, but when I try to connect a mouse it doesn't work.
Then I read that on CM based roms native usb otg isn't working. One can browse usb pens with apps, but no luck with other devices.
I don't care about storage, I need mouse/keyb and other input devices working.
Do someone use USB mouse or keyboard? What rom/kernel?
I'm starting to think it could be ICS since it was soo much time ago?
Thanks,
Robert

Thank you. With that combo I was able to diagnose a fault in the otg cable.
Repaired it and it works, now I'll try the other roms.
Both usb wired mouse and storage works perfectly with Sungsonic ROM v7 and Next Kernel 2.1.6
:good:

everything works fine on 4.4.x too. The fault was the damn usb otg cable.

[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

Have you tried it on stock with stick mount? Might be a rom issue

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?
