Dunno if they would work, btw with my kernel i have usb root showing up but cannot yet test anything because my usb hub seems to be broken and i don't have any usb female port lying around.

hey i can test it for you just send me the files and i give you feedback

Wow! Brilliant work! 720p recording?

That is really a big gift!

+1, I've build an USB OTG cable for the first ubuntu release (with Haret, launching from winmo) and since, he takes dust (french expression, sorry

)

Thanks in advance

Hi, Rick_1995, how about usb flash drives?

StompSC · Feb 14, 2012

Very Interesting!
I think, FTDI USB<>Serial Bridge also could work, if this is a later state?

Great news! Whish you all the best on work. This will give some new lvl of quality and boost standards which hd2 putted before as king of modding.

STOP POSTING UNLESS ITS DEVELOPMENT RELATED

Seriously, so aggravating continuously reading: "cant wait", "when will be done", "this is so cool"...this IS DEVELOPMENT TOPIC! Really wish I was a mod I would clean this thread right out...(ps. rick pm a mod and get them to do that)

While I am posting, good work getting this working

. It really is appreciated on so many levels, just too bad htc couldnt pay you guys in some way. Anyway thanks

I think dorimanx failed right where i am now, the ehci driver does not recieve any interrupts for usb device enumeration so even though the driver is up and registered, it does not get notified about the present usb devices.

Code:

cat /proc/interrupts
58:          0         msm  ehci_hcd:usb1

Rick,

Based on my research, switching usb modes is based on "grounding" 5th pin of micro usb via various resistors to trigger specific mode (usb otg; car dock; desktop cardle; headset through usb port for some devices...) its all being done within micro usb plug.
In fact he same logic is used in headset remotes (mic to ground pins via resistors).

I wanted to experiment a bit with custom crafted gear, but failed on lack of kernel programming skills.

Whish you best
And keep up the good work
Cheers

Edit:
By the way, i think that triggering 1A charge is done by briging d+/d- inside of the original charger. When i looked up the leo battery driver (back in 2010 though) the charge mode was relying on usb connection-when the connection to pc was established, than usb charge mode was trigerred(rather than wall charging). Thats what broke charging in decordes' linux distro kernel.

Cheers

Looks like this thing does not recieve any interrupts yet, can be either problem with registering the driver with the kernel or with not having supply the usb controller power (not initialised properly). I will return to this after 28th march due to my ongoing exams...

_________________________________________OUTDATED STUFF BELOW THIS____________________________________________
I am posting the alpha package for anyone adventurous enough to test since my usb CABLE seems to be broken

HOWTO Flash

Flash the attached zip (zeusk-dirty.zip)
Connect your usb setup to your device, (powered hub with devices already plugged in)
reboot to android (Boot will be delayed by "Extra" 120 seconds because of some issues with .acdb firmware for qsdaudio not being recieved)
use terminal emulator to gain su rights then insert the following modules in their respective order:
Code:
```
scsi_mod.ko
scsi_wait_scan.ko
sd_mod.ko
usb-storage.ko
```

HOWTO remove

reboot to recovery
mount /system partition
adb shell
cd /system/lib
rm modules
mkdir modules
exit
Flash any kernel of your wish

How to tell if it's working ?

Check LED on the device if present, then:
for usb mouse, you'll have a small cursor on screen
for usb keyboard, try pressing keys if inputs are registered
for usb flash drive, check if any device is listed in /dev/block (with name like sda or sdb)

OR

Try this

Post or pm your reports if it worked or not and please include the following:
dmesg
lsusb
cat /proc/scsi/scsi
cat /proc/interrupts
Android version you're using + the ROM
If the LED on any of your device/hub was on/blinking
If Host mode worked for you in WM6.5 or Ubuntu using the same physical setup

I recommend you do not use this if you had problem understanding ANY of the above.
The kernel i compiled is bare, and might have bugs which were fixed like color banding, robot voice and stuff, this is just a proof of concept.

What happened to your USB port? Is it fried or what? Is this safe to use?

Is this compatible with Sense 3.5 build HTC SensationXL 1.22 Android on TMOUS HD2?

Yes I want to try this but .. this " since my usb setup seems to be broken " stoped me .. is any way to broke our usb ports ?

clk package of this is needed.......

my usb CABLE seems to be broken, sorry for the confusion

and NO it didn't break because of this.
nope, no way of any damage to hardware. This is a .32 kernel so will work on anything but might have glitches.

shahabnoor said:

lol, too lazy right now to add clk support. ( just making a boot.img won't work, i have to add some clk stuff in kernel )
Also there will be a 60 second delay during boot due to some new audio stuff, so don't think your rom is bootlooping..

Can I add those modules into custom kernel(like dorimanx or tytungs) and enable it manually? Also, great work!

Unfortunately not.
The kernel modules are compiled together with a kernel, and are meant to work only with the one delivered with them.

Myself, as a cLK user, keep believing Rick will be generous (and diligent) enough to bless us with cKL-enabled test aplha package soon

Rick_1995 · Feb 17, 2012

nearly a day and no report ? should i assume it is working ?

I can't wait to try it but had no time to try it

Will try tonight after work...

I saw this in Dorimanx Kernel thread:

Dorimanx, here is working USB-host setup:
http://xdaforums.com/showthread.php?t=1459999&highlight=usb+host&page=4

Also tool to check if it's working:
http://www.xda-developers.com/andro...-host-capabilities-with-usb-host-diagnostics/

You could add this to your kernel, it's easy to do so and it works flawlessly on my device. All you need is a DIY powered USB cable or self powered USB-HUB.
There are modules and instructions how to enable them. Easy.

Why? Because having a big disk drive connected to HD2 is just...awesome.
And don't give that face of 'it's not possible on HD2'

It looks like it is working for him. Would love to test it myself but I need to order the right cables first.
