I found work of a guy who made USB host mode drivers for ZTe Blade, for stock ROMs. Since Blade and Racer have almost the same hardware, same chipset, Racer have hardware capabilities for that.

Here is the link Blade USB host mode drivers.

Is it possible to port his work to Racer ROM's? If so we'd have full fledged computer instead of phone .

Thank you

[vukodav]

Anyone have thoughts, or suggestions how this can be done? I'd help but I'm not a developer.

If someone can point this out to Racer ROMs developers, it'd be great

HEllo world !

I finaly manged to make kernel with USB HOST mode enavled. EVerything works fine except Racer camera, since I used deadlink's old sources and configuration

BTw, I'm writing now from my PCkeyboard and using my mose on Racer

[drway]

Great news, man! Maybe you trying different kernel, to fix problem with racer camera?

NICE

isnt deadlinks kernal#64 source code available? camera works with that, any luck asking vamshistunner on his source code ?

no luck with vamshistunner code

I don't know how to use git, and I downloaded sources from link on 4pda forum deadlink provided (it's Tom Giordano's sources). I also downloaded sources from his git repository, but after compiling kernel from those, I got stuck in booting loops

[vukodav]

Finally I managed to compile working kernel with usb hos mode enabled. Everything works fine now, camera, touchscreen.

Kernel is based on deadlink's source code. It has support for HID  devices (mouse, keyboard) and mass storage devices (flash memory, usb  sticks etc.), ntfs and fat file systems on storage devices.

If anyone is interested testing it I'll post it here.

Here is manual;

- First you'll need USB OTG cable/adapter, you can one make yourself - HERE is how, or you can buy one (google for it, or buy on amazon)

- Then you'll need powered usb hub which can provide upstream power to phone

- Kernel with host mode enabled


- Download attached usb_host_mode.zip. Unpack it and place usb_host_mode_kernel.zip and kernel_modules folder on root of your sdcard
- Flash usb_host_mode_kernel.zip with CWM, then reboot phone

After you get to desktop, use adb shell or terminal emulator (connect bot, or other) to load modules.

In shell type commands in following order:

su
 
 insmod /mnt/sdcard/kernel_modules/ntfs.ko
 
 insmod /mnt/sdcard/kernel_modules/scsi_wait_scan.ko
 
 insmod /mnt/sdcard/kernel_modules/usb-storage.ko  # ignore any errors when loading

As for using mouse and keyboard, just plug them into usb hub

Here is video how basicaly everything should look like



If anything goes wrong, don't hesitate to ask me.

Cheers

Exellent job man.Thanx.

it would be nice to make a video out too

connecting the racer to PC and see the screen there

Grats man . good work

[vamshistunner]

@ vukodav  Great Job man

You can also connect the mobile to your PC and control it.
checkout this cool application in market. there is a video too. It is just like an web OS. You can send messages, transfer files, etc from the PC. You can use the mobile screen on PC using this application, but its an add-on to the above application.

As vamshistunner pointed there are apps on market for controlling phone on PC. There is also a way to add bigger screen to phone over USB, framebuffer devices. But you'll have to wait for that cause I have to buy some usb to vga video adapters and test it first

Before I make anything stupid, I rather ask about things I can't seem to get clear about:
- my hub has B-type upstream port and does not provide power to the phone (it is not charging). What hub do you use in that video?
- does the phone automatically detect whether it is host or client based on the type of cable you plug in?
- can other kernel modules (e.g. Sven's for Blade) be used to experiment with other external hardware?
Some extra thoughts: managed to run Ubuntu in chroot - veeery slow but also very exciting. I can connect to it with VNC, but was wondering if it could use an external display connected to the phone directly via USB? I will throw out my laptop if that works
And finally many thanks for this topic!

[Dengem]

Good day all, I beg someone to get into this topic a schematic diagram for usb hostcable

[Dengem]

Give someone a scheme of this cable, please! p.s Sorry for flood!
and who will be able to port the kernel to gen2!???

First, sorry for late answer. I used common 4 port USB hub, and Y type USB cable. Y USB cable I used has two A male and one mini  B plug. I plugged one A plug to phone charger (it provides power to phone and hub) and the other in OTG cable, mini B plug is for connecting hub.

As for your other question, you can't use Sven's kernel modules. Kernel modules have to be compiled along with kernel with which they are used. I didn't compile modules for USB VGA adapters because I don't have hardware to test them with

I don't have scheme for this cable. I googled how to make it.

[Dengem]

and the voltage only usb Hub should do, or on the phone too??
