Great App It helped a lot when doing some tests with different devices. But, i tested with Xperia M dual and the USB host is not enabled. So i rooted my device and tried using the app fix option, but with no success. Now, the fix button is disabled and "A fix attempet can not be performed because of errors" Any ideia on how to proceed ?

"Fixed"... ... but not working. Must apply the "fix" twice and the app says my rooted Huawei G730 device has support now, great; however, it still can't read usb's. "Something" has changed indeed, since other usb check apps confirm the "fix" now. But no usb read actually. Funny thing is that, just to compare, I've installed this very same app on my rooted Moto G2, which has unarguable OTG capability and "USB Host Check" says it doesn't. So... what's going on here?

Awesome App Works like a charm. Just a click on Fix and you are done. Now, I can see my 500GB HDD connected to my MK802IV and enjoying the content on my TV. Root required of course!! And my Device is with a custom ROM so ignore the Nexus 7 thingy

Fixed USB digital audio output for HTC One max Couldn't get proper USB audio output from my HTC One max to the Sony MDR-1ADAC Hi-Res headphones. Luckily, my device is rooted so I was able to apply the fix. It now sounds amazing! Thank you so much for this great utility.

THIS WORKS!!! ( Rooted - Galaxy Victory/S3 on jellybean) Fixed missing xml files and made my Galaxy's built-in USB-OTG function. The ONLY APP THAT WORKS! Sorry Stickmount etc.. no need for them. Even the MassStorage for Samsung apk didn't work.This and "persist.sys.usb.config=mass_storage" to my "build.prop" Made flash/Thumb drives usable even with the crappy MyFiles even after un-rooting.. Developer Rocks!!! Small and simple fix. THANK YOU!!!

Nexus 7 2013 unrooted I won't root my Nexus because I need the security. This detected it might be fixed, but being uprooted, "su" did not work. This did it's job as well as possible. Be aware that some competitors to this want too much access.
