[Q] Accessing kernel output / UART debugging - Nexus 10 Q&A, Help & Troubleshooting

Hello,
Is it possible to access UART/serial data capabilities for kernel debugging purposes? ex. OMAP platforms can use a JIG on the USB GND-ID pins to enable UART and the FIQ debugger (in-kernel).

[Q] USB Host - Need full root?

I'm just going to assume that the DHD hardware is capable of USB host.
And that this will require a custom cable and external power supply.
And then there's probably some driver issue.
Which is where my question comes up; can we use the root we have, or do we need permanent root to be able to start working on USB host for the DHD?

USB ti serial

Does anyone know if you are able to use a USB t serial converter to connect to another device such as a Cisco router?
that would be neat if possible.. though you would likely need to compile the driver for the usb->serial chip into the kernel.

[Q] how can we use a usb host?

Hello,
I have do a usb cable with external power alimentation, can we use it on android?
It works on Windows and on ubuntu!
I have put the kernel with a driver for the usb host. If we search the program used in samsung s2?
Bumping, as I am looking too for a way to run this. There is no clear info about USB host support on this forum.
And USB Host IS POSSIBLE in HD2 as hardware supports it, probably with OTG mode. We need a working kernel, or just some info how to run it.

Quallcomm Diag port access locally

All, I am looking to get access to the DMSS or DIAG port locally on android without a USB cable. Perhaps this is done via usb virtual devices or some other means. Anyone try this?
Once you get access, a lot of modifications could happen on android itself.

[Q] RT2800 USB vs Monitor Mode

Hi,
I have just picked up a Note 3 on Three UK.
Am I right in assuming that the wireless chipset BCM4339 which is the same as on the Nexus 5 is still not able to use bcmon mode to allow us to enable monitor mode?
Would a specific ROM be necessary to allow a TP-Link WN722n (RT2800usb) to work on OTG cable?
I have tried both bcmon on my note 3 and also my TP-Link via USB OTG cable and neither have had any results.
Thanks
Toby
I've installed USB Host Check to confirm that USB host support is enabled on my note 3.
(android.hardware.usb.host.xml OK)
(handheld_core_hardware.xml OK)
I then installed USB Host Controller.
Both devices recognised but obviously not working. (Atheros USB 2.0 WLAN for TP-WN772n) and (ASIX Elec Corp AX88x72A) for USB ethernet.
When I run USB Host Controller I get the following error message:
"s3c usb host driver not found".
Another member on XDA posted a link to the Halaszk Kernel on the N9000 apparantly having OTG USB host support for S3C

I'm still hitting a brick wall on this one search wise.
Would stil love to be able to use my WN722N on my Note 3.
Has anyone any experience in modifying the Kernel Module to allow the ath9k to work on Note 3?
Getting a wireless adapter to work on Ubuntu or any form of Linux can be difficult if the manufacturer doesn't provide direct driver support or at the very least a "Tar" which would allow an end user (with sufficient skill) to compile the drivers them self. My understanding of this is limited but from what I can remember Android is JavaScript VM running on a Linux kernel. So you need the Linux source code for the driver which usually comes in a "Tar". Feel free to correct me if I am wrong.
