Hi!
I tried OTG on my Wildfire (CyanogenMod 7.1) but, naturally, it doesn't work.
It recognizes the cable like a dock station and active the pen drive but doesn't mount it: can add an OTG support?
I also tried the Chainfire's app (USB Host Diagnostics) but it didn't say nothing.
Thanks.
Bye!

I have CyanogenMod 10.2 on my Kindle Fire 2. Has anyone tried to connect cheap "chinese" USB webcam via OTG cable to the tablet? Is any possibility to get it work?
Does Nokia N1 got OTG support? I have Tried to connect my USB Flash through OTG cable but doesn't work for me ....
Doesn't work for me either >_<
I don't have an otg cable myself (yet) but can you try to use USB Host Diagnostics (available in play store) and post the report?
FYI I got an OTG cable myself and it didn't work. I dug a bit deeper and found out that OTG is most likely not implemented because Nokia N1 is using legacy usb controller over usb C - see below:
Converting USB 2.0 OTG SoCs to USB Type-C
While existing Device, Host, and DRD devices can be converted to support the USB Type-C connection with some effort, it is not practical to convert existing OTG SoCs. OTG requires a new state machine using the configuration channel to support USB Type-C. Host Negotiation Protocol is used to swap host and device role for OTG, while Power Delivery communication is used to change roles for USB Type-C. Combined, these challenges preclude simple upgrades of OTC SoCs to USB Type-C. - See more at: https://www.synopsys.com/Company/Pu...esign-type-c-2015q1.aspx#sthash.Ri02Guwe.dpuf

The only chance to get otg to work is most likely preparing a kernel patch (are the sources even available?) to manually switch the connector to host mode and power the attached device externally
After a bit of hacking around I was able to enable usb otg on my N1!
I've had a look at kernel sources for device with similar SoC (Nexus Player) and saw an interesting debugfs entry. To my surprise it worked like a charm and immediately detected the attached usb hub with a thumb drive, it even powered the hub so I didn't have to use an external power source!
To enable host mode, the following command has to be enterted in root console:
echo A > /sys/kernel/debug/usb/dwc3_debugfs_root/otg_id
Caveats (will try to find a way to resolve them):
- after enabling host mode N1, won't charge from the usb port - a reboot is required to enable the charging again
- probably same is true for pheripherial mode (connecting n1 to a pc). In theory, changing a to b in the above echo command should bring the tablet back to normal mode but for some reason it won't charge without a reboot so I'm assuming that same is true for non otg usb connectivity. Will have a look at the sources and debug messages to find out what's going on

Thanks for your hard job.
I have tried on my N1. It is amazing that otg did work. However, the otg can not coexist with charging function as yours. Hope someone could find a solution.

Hey,
Are you on Android 5.1.1 or 5.0 ?
I've had a look at the code of the usb driver of the a phone with similar chipset (asus zenfone 5) and it seems that the source of the problem is that the tablet fails to detect an appropriate charger type, which could mean either that the otg cable does not support this or the code of the driver does not work properly with usb C. Was wondering if something changed around this after the update?

Hi, mine N1 is still running the android 5.0.
I am afraid Root is the prerequisite to hack otg. Unfortunately, root is not available on android 5.1.1 till now, so even the android 5.1.1 driver support it, that won't help.
Thanks,dude.
Yeah exactly for that reason I haven't upgraded my tablet yet
I have a replacement cable.
I tried plugging in my device in my laptop using USB 3.0 port but it only charges my phone, it doesn't detect the MTP to transfer files. But when I tried plugging it in in the USB.. 2..0 port, MTP works.
My question is, is this because of the cable? Or is the A5 not supported by USB 3.0?

Mine works on a USB 3.0 port.
USB 3.0 should be backwards compatible to USB 2.0, so I think it's the cable. Maybe you could try again on a different pc? Just to be sure.
If you're using Windows check your device manager to see what it says, maybe a specific usb driver is needed?
i have same problem.
many time ago my phone (A5 2017) recognize with my laptop but after some update its not recognize in laptop but detect in office PC.
i do some work like change windows , reinstall add driver, use linux but not work in laptop. its now just work with one PC in office and other PCs not work. (
