[Q] acer a500 usb host problem

hi, i recently bought this tablet. the usb (full size port) used to mount usb drives, sd cards in cameras etc and the files could be seen on the device. of late, it seems the port does not mount any device, but provides power to it(thumb drive light flashes, phone charges). the file manager( file manager hd) shows "directory empty" when i connect a usb drive and choose it. please provide me with a solution. i tried rooting and un rooting the device but the problem presists. i tried enabling and disabling usb debugging but got no results. please help.
Try grabbing USB Mount All from the market. That should fix your issues.
Chlballi
Try using "USB Mount All v.1.3" available on the Marketplace. However your device will lneed to be rooted to use it.
may i know as to what is a usb mount? the iconia a500 already has a full size usb port.
got it, trying it out now.
thanks a lot. working like a charm

I've tried usb mount all but it doesn't help.
I'm running the virtuous 1.4rom

Guide to Xoom USB host with external storage

I use this USB host cable and it works great. Have tested it with my 750gb Oyen and 320gb WD Passport external HDD's, several usb flash drives (8-16gb), San disk USB memory card reader, and a USB keyboard.
For those having issues getting their Xoom to recognize USB storage devices here's what I've got and did to get it to work: I flashed my XOOM (3.1) to the 2.6.36.4 Tiamat_Xoom-v1.4.4-Full_Throttle Kernel and was unable to get the USBMount to recognize drives or storage at first. I installed USB Mass Storage Watcher from the market (it's free) and it works awesome! Can mount any storage I want (NTFS, FAT16/32, HFS, HFS+, EXT2, ETX3, EXT4) with any capacity. I think this app will work with any rooted Xoom (or other devices). Under my Kernel my USB host is located under/usbOTG.
Hope this helps.
Thanks for your post, im having trouble getting my Wifi Xoom usb host to work, i have tried making a cable from the tutorials around here and i have also bought an OTG cable but didn't get any luck having it working, im on HC 3.2 Tiamat 2.1.0 Tachi stock GPU , i tried installing busybox - OTG watcher - Drive Mount etc. and followed all kind of guides in the forum and on google with no luck, i tried usb mice , more than 6 flash drives, usb 3g dongles and other devices without any indication of any kind of connection or powering up, so most probably the problem would be from the cable...as i ordered xoom usb otg cables from ebay and until i receive them i was wondering if there might be anything i was missing?

Sounds like your cable is not OTG. A lot of them are not. Try it again with your Moto cable when it comes. Also, try rebooting with the cable and drive plugged in, with OTG Watcher running. That has worked for me in the past.
Xoom 3G, stock FW 3.2, non rooted and ot cable
So - just installed USB Mass Storage Watcher OTG - https://market.android.com/details?i...tcherotg&hl=pl
Pendrive is recognized by the program immediately and displays the mount point /dev/block/sda - but unfortunately the next value is 0MB. And this is like that on every pendrive. Do I need root to mount it, or do you have any other idea to mount my pendrive without root?

You do need root to mount the drive-to use Xoom in USB Host Mode.
Only root? Is that all that needs to be done?

You need a kernel or rom that supports OTG. Tiamat Odachi kernel, Moray rom, the 4G rom, and the Rogue Rana kernel should all support usb host mode. You will also need a real otg cable and probably an app that helps you mount the drive, such as USB Mount All or Drive Mount.

it works great on rooted stock kernel 3.2 with "Drive Mount" but from the market you can not install "Drive Mount" it says not supported.
If the program is free could someone post the apk?

You got it to work using that USB adapter? That's not a USB OTG adapter. It really shouldnt work using that one.

Everything works only if its Fat32. NTFS needs new kernal loaded. I am Rooted but Stock. 4.0.4.
Reboot loop after trying to get external USB to work
My Xoom WiFi running Team EOS build 102 would not see my USB drives. I installed 'USB Mass Storage Watcher' from the market. This app then prompted me to install the OTG version. I followed instruction and removed original version before install the OTG version. The OTG version also prompted me to down load another version of Busy Box, which I did.
I could then see one of my USB (see size and space used), but could not see files or folders in the mount location. I restarted my Xoom (I live in a windows world and reboot fixes a lot of issues LOL), Xoom got stuck in reboot loop. I went into recovery mode and clear my Dalvik, but this had no effect on reboot loop.
Luck for me I had a Nandroid backup from 2 days earlier (pheew). Restored this and back to normal.
Not sure if anyone has had this problem, but I strongly recommended making nandroid backup before doing any device driver updates.
No Prob...
im on the same software version as u, i connected usb drives, mouse and keyboard without any problems, just wanted to let u kno

[Q] Native USB OTG Storage Support

Hi,
there are many ROMs out there for our beloved Nexus 10, but it seems that only few support external storage via USB OTG. I couldn't figure out how to enable it manually. Is there any kind of mod or kernel that does the trick? I tried some apps on the play store, but I don't like the idea of an app sitting between the android system and storage hardware.
Thanks in advance!
Cheers,

I think all custom kernels have USB OTG support in them, and maybe I am ignorant since I dont care about OTG support but I thought all "major" ROMs worked with them. Hmm.
Maybe you're right, but in that case USB OTG seems not to necessarily include USB OTG storage. I noticed, that while ParanoidAndroid did not recognize my USB storage device, it was still able to detect things like mouse and keyboard correctly.
Example:
[ROM+KERNEL] [AOSP] AOSP+ 4.2.1 - JOP40D - Cust.Settngs+OTG+OC+More - 20 Dec 2012
http://forum.xda-developers.com/showthread.php?t=1998585
USB OTG Information:
1. Auto-mount to /storage/usbdisk
2. Files accessible by all applications, processes and users
3. Currently works with FAT & NTFS partitions
4. Full read-write access for FAT USB disks, read-only access for NTFS USB disks
5. This does not conform to the Android 4.2 multi-user capabilities. All users have full access to the OTG storage
6. If you are using another custom kernel, make sure it does not overwrite the ramdisk changes or you make lose OTG support
I am sure there are other ROMS. Do a "OTG Support" search in the "Nexus 10 Android Development" forum and find what suits you.
Cm 10.1 and AOKP both support native OTG for USB drives. :thumbup:

ROM? try root + StickMount + *browser for root
ops! i didn't read the last part of you post :/
thanks for your replies,
it seems like the only up-to-date ROMs that aim on native USB OTG storage are indeed cm10.1 and aokp.
however, apascual89's paranoidandroid might soon support it too.
i think that is worth having an eye on it.

[Q] USB host controller issue

No device connected to the micro USB host through OTG cable is detected. Neither mouse nor keyboard or (micro) SD Card. The kernel claims to support USB host controllers. Checked with three different OTG cables, all sold claiming to work with Nexus 7.
Everything was also checked on stock ROM and kernel (JDQ39) unrooted and rooted.
Same cables work like charm with my i9305 Galaxy S 4 LTE just as Stickmount and Nexus 7 Media Importer (mouse, keyboard, storage).
Nothing works however with my Nexus 7. I feel very frustrated and cannot resolve this issue no matter what I try.
Any ideas?
Thanks
Nexus 7 grouper, rooted, Stickmount, Busybox installed
OS: JDQ39 based Smooth rom 5.1
Kernel: M-Kernel 3.1.10
Try a different kernel... Bugs do happen so OTG might be brought ken on that kernel.

PS: I know bricked worked, I thought Franco's worked too. Dunno bout M-Kernel, I actually avoided that kernel because it didn't look like USB-OTG support was in it when I searched the thread.
Thanx answering
I'll try Franko. As I remember, M-kernel has OTG support. But
Shouldn't even stock kernel support keyboard and mouse over OTG?
And why does the Nexus Media Importer app not work either? That
doesn't even take root...

Depends on how you're implementing it. I know with apps like StickMount and OTG Helper, they won't automatically start media scanner on the new device unless you have the paid version.
The rom in my Sig actually has USB-OTG support for the Nexus 7 built in (would still need a kernel that supports it of course), so it automatically mounts a thumbdrive, and it shows up under Settings -> Storage , and shows as USB Storage and you can unmount it from there, acts just like an SD card would on other phones. Only downside is no exFat support (nor NTFS I think). Stickmount can do it but you have to provide the exfat binaries in /sdcard.

Stickmont free detects connected USB storage immediately and mounts it. The USB drive and the files on the device connected by
OTG can be seen by any file explorer in a normal case. Also, when connecting mouse and/or keyboard (even wireless)
via OTG/OTG&USB hub a USB icon and a USB device connected message should pop up in the notification
bar. Nexus Media Importer app should also see the connected device if formatted FAT32.
At least, that's how it works on my Galaxy S3 using the same hardware ( 3 different OTG cables,
mouse, keyboard, USB sticks, memory cards, etc.)
I have flashed four different kernels (M, Motley, Franko, Stock). There is a significant difference in
performance but unfortunately not in USB host device detection behaviour.
I do appreciate all your helping effort. Thx

[Q] Mount USB Storage On Nexus 4

Hello guys!
I got my Y OTG CABLE yesterday and I wanted to plug my external HDD into my phone. I tried everything yesterday but i couldn't make it work. The disc was turned on but I couldn't see it on my phone. I tried many apps that they were supposed to do the job (like stickmount) but no luck.Can you help me fix it? I have This Kernel and I'm on Android L
Solved! Checked usb otg option on Synapse app that comes with kernel, saved changes, installed stickmount and plugged my external hdd on otg. Note: i checked su on boot on supersu because some times was kinda hard to connect external devices.
