An experimental CM7 Kernel

[Guest wishmasterf]

Is there a way to get that changes integrated in official CM7?

It's been logged in the tracker.

Rebooting into clockwork and running the two USB OTG zip files in this forum on the latest official version should work. Its working with CM7-07242011- Nightly for me. Give it a try!

For people who want to experiment serial don't forget that rs232 is 12 V

Never try to connect the blade directly to a serial port !

You need an adaptor

In conjunction with the above, a tty-RS232-usb board - that can be easily obtained from some shops that specializes in electronic components, possibly ready made, that converts the signal from 12v to 5v then you should be okie :)

Btw, I mentioned tomm's case to my brother who is electronics engineer and was working on a few USB gadgets in the past years. The immediate response was: Ha!Ha! You are challenging your gods if you connect it this way.

The background is that this "5th pin circuit thing" exists for a reason. It signals the OTG controller to enable its own self-clocked charge pump, to bring the supply voltage to 5V from whatever the battery currently provides. However, if you create a conflict with another (self-clocked) switching power source then all kinds of damage can happen, including tomm's problem. Depending on their internal design, sometimes they work along but you better don't try.

And there are rumors that this "usability issue" is known to USB implementors and somebody already works on improvements of the USB charging spec. We will see.

[Guest DB_Runner]

can anybody explain this failure? I used a powered hub with connected keyboard

@ h4z7d: i can now use a usb mouse connected with the blade but the keyboard doesnt work. What keyboard do you use ?

I've used a number of keyboards with all with success. Maybe there isnt enough power?

Heres my Dmesg with a usb keyboard attached:

I've recently made a USB cable as per my description in previous post. It works excellently. I've been using it in conjunctioin with New Trent IMP660 (http://www.amazon.co...y/dp/B0050DYZ1M). Its an excellent power pack, I highly recommend it.

Unfortunately I still get reboots when connecting/disconnecting a USB OTG device.

I'm looking to get a usb Wifi dongle working with ubnuntu on my phone for Aicrack-ng. Should make it a great portable security tool.

[Guest kol0bok]

Hi, today I got my fingers on an OTG adapter (definitely working on Galaxy S2) and decided to play with OTG@Blade. I used TomG's kernel source repository (2.6.32-zte branch) and the .config file from johnsmithx's posts (cyanogen_blade_gen2_defconfig). Mostly following the Howto from http://android.modac...t/#entry1553367 slightly modified for the current situation (gen2 baseband offset).

However, I do not see any reaction when the cable is plugged in. Absolutely no news in dmesg output. After reading more of this thread, I understand that Blade does not provide a power source... ok, but then I think I should at least see some report about mode switch of the USB controller?

[Guest r3z492]

how the steps to enable the usb host on zte blade froyo 2.2.2

kernel 2.6.32.9-kernel-perf @ Zdroid zte-SMT

I am sorry im newbie

Me too!

Please.

Install CM7, install the two USB_OTG.zips in this thread.

[Guest WildeRNS]

Install CM7, install the two USB_OTG.zips in this thread.

on gen1 or gen2 too ok?

[Guest r3z492]

For those of you who have the OTG cable adapter, try this kernel from here and report back on this thread :)

B)

can you upload again, cause this link is not valid,

I dont get any report without connected power source.I think that is normal.

My keyboard requires only 40mA, the mouse 100mA. I think power is not the problem. Maybe the multimedia keys cause the problems. I have ordered a new keyboard, hope that solve the problems.

Any idea what cause the reboots? That problem is really annoying.

Have no idea why it reboots - perhaps a power surge or something that has knocked out the USB subsystem - just be careful that you don't fry the blade like what happened to me :)

[Guest fp30]

is kernel debug shed_features enabled in this kernel?

Not sure... do not recall adding debugging features.... unless someone who has it actually working to extract the kernel config and pastebin it for you to look at and verify :)

I thought this might be relavent to your issue with it not detecting keyboards :

You might need to add vendor codes.

thx for the hint! I will try to add the required vendor code for my "old" Cherry keyboard. Fortunately my new keyboard works perfectly with the blade.

Any progress with your usb wifi dongle experiment?

I have heard that not the usb otg experiment killed t0mm13b his blade. A faulty usb socked caused the sudden dead. So i hope that nobody have to be afraid to kill the blade due testing usb otg.

Glad to hear that your new keyboard works.

I've run into issues with compiling the driver for my wifi dongle. I think I'll have to wait until android.git.kernel.org is available again. I've got lsusb in my chmod ubuntu instance displaying my wifi card, now all I need is the driver!

[Guest WAWA72]

tOmmi3b killed the USB Hardware. One Pin was broken.I repaired this Blade.It was not faulty from experience with USB-OTG

[Guest JoshuaHiggins]

I've looked through masses of posts, and even other forums and still have no success getting USB Host mode to work...

I've got the 179 nightly, all the correct hardware, I've got the USBOTG zip file, but I'm a little unclear how to "install" those files, as they fail to run in Clockwork... I've been trying via "install via zip" option, but it aborts on all attempts.

I've run the zip with both files, with them both extracted, and it continues to fail.

Could someone tell me what I'm doing wrong, and possibly explain how to execute this properly?

If so, any other advice regarding OTG would be useful too, such as using dmesg, so on.

I've been trying this for months!! :P

Thanks, any help would be GREATLY appreciated! :)

- Dont extract the zip files.

- Copy them to your SD card.

- Reboot into clockwork (recovery).

- Choose "Install Zip from SD Card", "Choose zip from sdcard", run usbotg.zip and usb_otg.zip

- Reboot back into android

- Check - Menu > Settings > About Phone > Kernel Version - should read: "2.6.32.9-perf t0mm13b@tribbles#1"

- Connect appropriate cables powered as per advice in previous posts along with USB keyboard and/or mouse

- At this point phone may reboot, if it doesnt I would reboot it anyway. I've had issues with hardware not being detected without a reboot.

- Check if it works, if not do the following:

- Open a terminal and write "lsusb > /sdcard/lsusb.txt" and then run "dmesg > /sdcard/dmesg.txt" This will create two files on your sd card. copy the text and post it up here. Make sure you use the "Insert Code Snippet" when you post up dmesg and lsusb logs here.

[Guest DB_Runner]

is it really necessary to install both zip ? I thought only the newer one.

I assume, since new kernel (2.6.35.7) we need a adapted patch to use furthermore USB OTG at the Blade.
