Hello,
I have an issue with my U8800.
It is not detected by my PC (Windows 7 x64). When I say it is not detected, I mean nothing happens. Tried all USB ports. In fact, I have tried the phone on 6 diferent PCs (4 with windows 7 x64, 1 with windows 7 x86 and one with Vista x86). The best I could get was usb not recognized (but very quickly) in one of them (x64) but not replicated. It doesn't matter if you go to Pink Screen, with battery, without battery, with sd card or without, etc. Have tried forcing all kinds of drivers, without success. Android SDK is fully installed, etc.
I also tried using 2 diferent Linux live OS's. On one of them, I was able to mount the "CD - the one with the drivers", but again, only once.
I was using Aurora with latest update when this issue started. Never partitioned. I have downgraded to Rom 136. Tried B517 and B528. I'm only able to root the device using Z4root with froyo.
Tried 3 different cables and all of them work without any issues with a Galaxy S3 and a ZTE Racer.
The funny thing is that the U8800 is detected by my car audio system (it uses windows CE 5.0) and plays media files fine. Even the USB Debugging shows up. On another car, with a "usb radio" it also works.
The device itself charges fine in every usb port i have tried
Any help would be appreciated.
Thank you
Hi guys, just an update.
I forgot to mention that the device itself does nothing while connected to the pc. No USB mount or USB Debugging icons. Just the charging message and the lightning icon.
I have tried the device on 5 more PCs and 3 more cables. Not much luck. I did get a few odd behaviours.
This is what I have found out:
Windows 7
With the phone OFF:
If I just plug in the usb cable, it will turn on and after a few seconds, the battery image will appear. While doing that, by using UsbDview, I can see USB Mass Storage Device with the idVendor=12d1, idProduct=1037.
Windows displays "Unrecognized usb device" and a pop up says that windows was unable to find/install drivers for the "unkown device" (error 45 - device is not connected).
Phone turned ON:
If I turn the phone on, no error is displayed and no attempts to install drivers are made. Nothing happens.
Ubuntu (12.0x) - Using the same method with the phone turned OFF:
Dmesg displays:
usb 5-1: new full-speed USB device number 5 using uhci_hcd
hub 5-0:1.0: unable to enumerate USB device on port 5
If I insist, by removing the usb cable, a few times, I get this:

Phone turned ON:
Only when this information is displayed, If I turn the phone on, it will connect to linux. Usb debugging will come up and I'm able to mount the SD card.
This is very weird. Can anyone help me with this issue?
Hello again,
Over 100 views and not a single idea???
One thing, when I connect the phone to Ubuntu (not in pink screen, as it doesn't work), the internal memory is seen as unallocated. Is this normal? It say 2.0GIG but no file system. I have access to the internal memory on the phone itself. Could this be a clue (The external SD card is visible and accessable).
When i type adb devices, no device is present or if I use adb shell, error: device not found.
lsusb and dmesg show the device.

Come on guys, I don't believe this to be a hardware issue. Please help!!!!!!!!!
P.S. I still have IMEI, serial, etc.

It is a strange behaviour. The only thing I could recommend you is dial *#*#2846579#*#* and see the usb port setting. On stock ROMs you should be able to change it to something like "normal" or "google".

Belfish, thank you for the reply. I have already tried that. Same result. Someone has suggested if the vold.fstab file has been moddified. I have never touched it so I don't know what I'm looking for. This is what's inside the file:

Is it supposed to be like that?
Thanks.
The vold.fstab shouldn't matter much. If it is wrong, then it would not let you mount sd card in android too.
I don't really know how to help you. I know there are some NV items that could alter the USB interface, but it's mostly in the kernel side. Maybe you can check your "dmesg" log on your phone. Using a Terminal Emulator, first write su for superuser and then dmesg. It gives you the kernel log messages in Android side (the phone).

Ok, I will do that. I just need to go back to 2.2 so I can root it. Once I have the Logs, I will post it. I really hope to solve this so I can try your new rom. Thank you Blefish
P.S. Is there anything I should be looking for?

Hi!
Just got an HTC Magic that was locked on Vodafone Spain. The phone is great, but I seem to have a problem, I can use it as a USB mass storage device.
When I plug it to the computer using the USB cable that came with the phone, the USB notification doesn't shows up, so I can't use the mass storage...
The microSD card has 8GB of capacity and it seems to be ok, at least I can take pictures and saved to the card...
I have tried on Linux(Ubuntu 9.04) and I got the following errors on syslog:
Code:

I tried to connect it to Windows XP, it appears an error installing the hardware, then tried to install the USB driver that comes with the Android SDK but with no luck
I have already made a reset to defaults on the phone, but I still get the same problem.
Does anyone knows what could be happening and how can I solve it?
Thank you all.
I don't know if its important, but here is some more info on the phone:
SAPHIRE PVT 32B SHIP S-ON G
HBOOT-1.33.0007 (SAPP10000)
CPLD-10

Have you create the needed udev configuration for your HTC?
In order to mount correctly a HTC Magic you have to the following udev configuration file.
Code:
sudo gedit /etc/udev/rules.d/50-android.rules
And paste the two following lines. Do not forget to change USERNAME with your Ubuntu username
Code:
SUBSYSTEM=="usb",SYSFS{idVendor}=="0bb4",ATTR{idProduct}=="0c02",SYMLINK+="android_adb",MODE="0666",OWNER="USERNAME"
SUBSYSTEM=="usb",SYSFS{idVendor}=="0bb4",ATTR{idProduct}=="0c01",SYMLINK+="android_fastboot",MODE="0666",OWNER="USERNAME"
After that you have to either reload the udev configuration or restart udev. To be sure restart udev.
Code:
sudo /etc/init.d/udev restart
I hope this will help youto resolve your case
Thank you for the reply, but I have already done that...
Also, I have pluged in another HTC Magic(a 32A version) to the same laptop and it worked ok
I cant understand what is happening ... can anyone else help me?
If I put the phone in Fastboot Mode, connect it to the laptop, and run the command
Code:
fastboot devices
I can see the phone... but using it as a usb mass storage, nothing happens
its probably hardware then. get them to replace the phone for you.
Humm, thats bad news
The phone is in second hand and I don't have the receipt of the purchase. I will ask the seller if he has it, if not, I guess I will not have a chance to put it to repair under warranty
Also, I have already installed the Cyanogen recovery image, so I guess that would void the warranty, right?
Pushing this topic to the top, has anyone else had this problem?
I had the problem on mine once but it was just related to one pc.
Removed all the drivers off the PC and it worked when I reconnected
@skhell
I don't know where you would find it for a 32A, but assuming you did not change your SPL you can use Fastboot to completely flash a stock config (system, recovery, boot, data, etc)
For instance, Cyanogen's instructions have you fastboot a SAPPIMG.nbh for 32B devices, I am assuming such an image exists for 32a devices as well...
If you can completely re-flash the entire system your warranty claim should be fine.
Yeah, I can restore the phone right as it was originally, the problem is that I don't have a proof of purchase to put it into repair under warranty...
Hi,
past days I tried to run usb networking on my ipaq, but with no luck. I traced GPIOs with haret, relevant to USB are 99, 78, 39, 47 - when I plug/unplug the cable to the computer; 13, 78, 99 - when plugging/unplugging to power source, so I believe GPIO #78 is USB_PULLUP. (GPIO #99 was detected as battery door) I tried it and the output was following:

I tried connecting usb cable prior to booting, but it didn't help.
I discovered also some other GPIO ( #83 ) is changed when managing USB settings - when I go to "USB settings" and check "enable faster data synchronization", this GPIO value is set to 0 and then to 1. When I check this option in WinCE, new network adapter appear in Windows host. If I uncheck it, the new adapter disappear and GPIO is set to 0 and then to 1.
Is this GPIO relevant too ?
Has anybody some ideas / suggestions what to do?
thanks
Has anyone tried Defy's USB Host mode?
Would like to attach USB devices onto Defy:
- USB keyboard / mouse
- USB disk drives
- Other types of USB 3G modems (like CDMA1x/EVDO)
- Arduino IO board
...
I haven't bought Defy yet, but want to do some pre-research before the purchase.
Could someone do me a favor to post the outputs of "dmesg" on Defy?
(Run dmesg command under the Linux console).
I expect to see something like:
Code:
...
OMAP3630 ES1.1
...

musb_hdrc: version 6.0, musb-dma, otg (peripheral+host), debug=0
musb_hdrc: USB OTG mode controller at fa0ab000 using DMA, IRQ 92
...
I got above dmesg by Web searching for an OMAP3630 test board, not a Defy.
Just want to make sure Defy is equipped with USB OTG controller.

Understood the bootloader is locked by Moto, and a kernel must be signed.
Instead of replacing kernel itself, can we just load new driver modules (*.ko via insmod command)?
Does Moto also prevent from loading customized driver modules?
Can someone help to get the outputs of "cat /proc/driver/musb_hdrc" ?
Something like:
Code:
#cat /proc/driver/musb_hdrc

One correction to my previous command line for current USB mode:

How about to use:

to enable the Host mode again?
May run command "modinfo musb_hdrc" to get actual parameters we can use to enable the Host mode.
Something like "modprobe musb_hdrc mode_default=1".

No, we really can load own driver modules....
sent from my moto defy with taptalk
It would be very great if this will work.
Is there any progress?
yeah, be nice to connect 2 usb hosts so i can copy my slr pictures from a 32gb sd card over to a 320gb hdd.
I have usb y cables so i can power the hosts with an external usb charger.
Any news on this?
It will be nice to see an USB host patch/mod on Defy
hi
I've seen that some phones will enable host mode if you boot them with the data pins shorted, done with a "dongle". anyone tried this on the defy? I'll make one and try it if no one has.

hmm.. is that safe? I dont want to burn my usb port..
I doubt it will damage anything. they won't be able to source enough current.
I've checked and the omap3610 supports usb otg. I will try to test this weekend.

Scratch that, it is not the data pins, you connect the "extra" pin (pin 4) to ground.
Maybe 2nd ini make this able...
Guys, i saw something on Blog.Makezine.

Maybe this could help, would love to be able to play video files from a external HDD. Watching movies on the backseat while we drive to our vacation!
maybe we need another kernel,i think
I am attempting to connect to a serial device from a Android tablet, via
USB-Serial Converter. In order to interface with this particular serial
device, a linux library must be used as an interface.
This library takes an integer as an argument, and tries to connect to the
device at the following location : /dev/ttySx, where x is the arguement. If
2 is provided to the library, it will look for the device at /dev/ttyS2.
Very simple.
When I connect the device to Ubuntu, there's is one simple extra step for
this device to work with the USB-Serial convert. The converter is exposed
at the location /dev/ttyUSB1. I just need to create a simple soft-link with
the serial port pattern (etc "ln -s /dev/ttyUSV1 /dev/ttyS99"). It works
perfectly.
Now the problem arises for Android. The converter is seen at
/dev/bus/usb/01/01. I never seen this convention in other project. The
question is how can I direct the I/O from /dev/ttySX to /dev/bus/usb/01/01

Which android device are you using and with which kernel and android build? In my case I am using kernel 3.0.+ with CM9 on a Kindle Fire and I do see the /dev/ttyUSBx getting created along with the /dev/bus/01/01. It has been a month since I tried it but I was able to see the problem you see and here is what I remember. When you plug the serial convertor both /dev get created but since the Android USB support only uses /dev/bus/usb/01/01, the kernel in order to save power "unmounts" the unused /dev/ttyUSBx after a certain time period. You can try using dmesg to see if that is happening in your case also. There is a kernel build flag that tells the kernel not to "unmount" it but I dont remember it off-hand. Best would be to use the Android USB support to talk to your device instead of the linux library if you can.
--------Update after testing it out again and checking dmesg etc---------------------------
When I plug the FTDI cable this is what shows up in dmesg:
<6>usb 1-1: new full speed USB device number 8 using musb-hdrc
<3>usb 1-1: device v0403 p6001 is not supported
<6>ftdi_sio 1-1:1.0: FTDI USB Serial Device converter detected
<6>usb 1-1: Detected FT232RL
<6>usb 1-1: Number of endpoints 2
<6>usb 1-1: Endpoint 1 MaxPacketSize 64
<6>usb 1-1: Endpoint 2 MaxPacketSize 64
<6>usb 1-1: Setting MaxPacketSize 64
<6>usb 1-1: FTDI USB Serial Device converter now attached to ttyUSB0
At this point if I check the filesystem I see both /dev/ttyUSB0 and /dev/bus/usb/001/0xx [ xx being the current device number ]
I can work with /dev/ttyUSB0 and all is well. Now as soon as I invoke any app that uses Android USB Host Mode API to connect
to USB (for enumeration, connection or whatever) the /dev/ttyUSB0 gets disconnected with following message from dmesg:
<6>ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
<6>ftdi_sio 1-1:1.0: device disconnected
At this point /dev/bus/usb/001/0xx is still alive and if I enumerate the USB devices using android API I see the same as the adaptor
name. So looks like till the Android USB API takes over the FTDI is available as /dev/ttyUSB0 but not afterwards.
------------------------Update ends--------------------------------
(a) If you see a /dev/ttyUSB1 device node created, then you can try the following in an Android terminal:
Code:
stty -F /dev/ttyUSB1 raw
cat /dev/ttyUSB1
If this shows data from your device, then you can use directly the device node to read()/write(), POSIX-style, without needing any library.
(b) If you cannot see a /dev/ttyUSB1 in your Android device, this means that you need to load the ftdi_sio kernel module (check android.serverbox.ch/?p=285 for instructions).
Let me link that for you:
"How to enable FTDI Support for your USB Host featuring Honeycomb Tablet (including sample native application)"
Also have a look at FTDI's Android Paper:
"White Paper: Connecting Peripherals to an Android Platform"
and this relevant blog, from this XDA thread.

are you using ftdi's code to modify it?
change /system/etc/permissions
this is from a question on stackoverflow titled "Android USB host and hidden devices" (sorry, i can't add external URLs yet). it worked like a charm on a micromax A120 canvas 2 phone (kitkat 4.4.2). now i can control my Arduino! i used busybox tools to do all the command line work (otherwise chmod wouldn't work). my steps (perhaps some were not required):
(0) install PDAnet drivers on my Windows 8 computer.
(1) root the phone using Vroot (now called iRoot). Very simple, only catch is that the su grant/deny page is partly in chinese, no big deal.
(2) install busybox and jackpal's Android-Terminal-Emulator available on github and the google play store (free).
(3) open a terminal window and become the superuser:
# su
(4) the file system may be read-only, so you might have to remount it:
# mount -o rw,remount -t yaffs2 /
or
# mount -o rw,remount -t rootfs /
or
# mount -o rw,remount -t rootfs rootfs /system
(5) make default.prop read/write:
chmod 666 /default.prop
(6) edit /default.prop, make the following changes:
ro.secure=0
ro.debuggable=1
persist.service.adb.enable=1
... And this is the real meat of it:
(7) To enable USB host API support you should add a file named
android.hardware.usb.host.xml and containing the following lines:
<permissions>
<feature name="android.hardware.usb.host"/>
</permissions>
into folder
/system/etc/permissions
in that folder find file named
handheld_core_hardware.xml or tablet_core_hardware.xml
and add
<feature name="android.hardware.usb.host" />
into <permissions> section.
(8) Reboot your device. Usb host api should work.
USB debugging on Linux
Maybe it's just me being blind, but does anyone have `adb` working on Linux? Device ID shows up as 0fca, and I've added this to my udev rules, but still no device. Notification shows "USB debugging connected - Touch to disable USB debugging" with "Media device (MTP)" and "Camera (PTP)" USB connections.

Thanks!
Figured it out. My Linux environment (Ubuntu 14) had the package 'android-tools-adb' installed, but that version of `adb` doesn't seem to work. The `adb` binary with the SDK tools works fine. I removed the 'android-tools-adb' and all is well again. :laugh:
