What are you using to power the OTG? The N4 doesn't supply power for OTG no matter the kernel... you need to supply external power to the OTG device, something like this Host OTG Cable with Power connector or it won't work.

hi,
It looks like you have the same issue as the Galaxy Tab 3 7.0, not usb-otg capable.
I don't know kf it has to do with Marvell hardware/components but, it's possble it does.
Head over to the Galaxy Tab 3 forums and see the threads on otg for the Tab 3 7.0

on the marvell based models no. but from what i've been seeing today the sm-t237p degasltespr is a qualcom/msm device, if it has the proper usb connector on board , that may be a maybe ? :silly:
from the kernel source;
Code:
The most notable feature of USB OTG is support for a
│ "Dual-Role" device, which can act as either a device
│ or a host. The initial role is decided by the type of
│ plug inserted and can be changed later when two dual
│ role devices talk to each other.
│
│ Select this only if your board has Mini-AB/Micro-AB
│ connector.

[Q] Galaxy Tab 4 7.0 USB Host

Hallo, my english is not good, but I try.
If you german or frensh language can, it is good, but...
I have a Samsung Galaxy Tab 4 7.0.
Android 4.4.2
This device can not USB Host.
Two problem:
1) The originel kernel let not the function USB host free.
I thought, with a new kernel it is maybe possible.
I have root my device with Odin 3.09 and" openrecovery-twrp-2.8.0.1-degas.tar".
Now, current kernel:
3.10.0-4756355 [email protected] #2 Wed Apr 22 16:50:01 KST 2015
Builnumber: KOT49H.T230XXUOAD2
SuperU, Titanium Backup, Root Explorer and NextApp SDFix work good.
But I have not USB Host and USB OTG not do.
2) The USB device require more power (a USB-stick with 4 GB)?!?!?
Do you know This problem?
Is there a kernel-version for this problem?
Is it a power problem? (for a USB Stick 4 GB?)
Apropos, my Galaxy S5 operate verry goob with USB OTG...
Thank you for the help and best regards.

RD9700 drivers for Nexus Player

Hey everyone!
I'm running the Nexus Player with the 3.10.20-g43ab991 kernel and Android 7.1.1. I've bought a Micro USB to LAN adapter and it has the RD9700 chipset which is sadly not supported by default. However, I've found this post and they made a driver - unfortunately, for a very old kernel version.
Has someone this driver for newer kernels or could compile it for new kernels (unfortunately, I'm a total noob at this)?
Thanks!
I have no experience with that particular product but I can tell you that the TP-Link UE330 works with an OTG adapter cable.
