Issues with USB connectivity etc. and root / A2SD

[Guest ZiCoN]

I have pursued this with Koush... he has sent me the link to the code for that part of recovery and i'm investigating.

P

Fingers crossed :) Thank you so much for the efford ;)

[Guest potter97]

Several of us actually believe it could have been caused by us turning on the mass storage in the amon ra recovery... As far as I know, all of us with this issue have at one point or another turned it on.

My thought is though... If this could switch something off in the SPL, would it be possible to look at the coding for that part of the recovery.. and that way find out what happend?

Ah ok i can see how now :D

Yea i did not mess about with that option, Phew.

Well hopefully Paul will get you guys back on track :) I belive in him totally, hes a very smart guy, wish i had a tenth of his skills ;)

give me a minute and i'll try, just need to install connect bot

[Guest ZiCoN]

file: not found (used connectbot)

[Guest jeckyllhavok]

Ok, i'll tried with the testimage, but in /platform there is no usb_mass_storage

[Guest ZiCoN]

Tried it EXACTLY as you wrote it... :

cannot create /sys/devices/platform/usb_mass_storage/lun0/file: directory nonexistant

[Guest jeckyllhavok]

I been using loads of rom's and recovery usb mounts without a hickup. I been re-flashing my Desire at least 30 times now so.

I used a goldcard for a2sd and root tho. No errors so far.

[Guest jeckyllhavok]

Could amyone with a working phone look if it's there

[Guest geek78]

On a working desire:

ls /sys/devices/platform/usb_mass_storage/

uevent

modalias

subsystem

power

driver

mass_storage_enable

Hmm.... there is a directory that might be of interest:

/sys/devices/platform/usbserial/

On the HTC Kaiser when we tried to port android, we could see the whole commandline a booting, there was mtty always turned of, maybe usbserial means that we start with mtty turned on and not in pure usb mode

[Guest yabolek]

What does cat /sys/devices/platform/usbserial/serial_enable say on a bricked Desire?

On a working one, it says "0"

Says 0 for me, too on a bricked one

[Guest jeckyllhavok]

What should logcat say if you plug in an usb cable

[Guest yabolek]

What should logcat say if you plug in an usb cable

On a working Desire, with automatic SD mount.

logcat_usbconnect.txt

[Guest r&a]

On a working Desire, with automatic SD mount.

its been partially checked here

http://forum.xda-developers.com/showthread...2970&page=9

and as i reported on #86

all this section is missing on bricked units

cat /sys/devices/platform/msm_hsusb/usb_function_switch

[Guest dimor]

And here it is - http://github.com/koush/android_bootable_r...commands.c#L367.

I would be interested to see what happened if someone with a broken phone installed ConnectBot or a similar terminal application and input 'echo /dev/block/mmcblk0 > /sys/devices/platform/usb_mass_storage/lun0/file'.

P

cannot create /sys/devices/platform/usb_mass_storage/lun0/file: directory nonexistant

for me too...

[Guest Biliskner]

bah. no write access to the /sys right? so we cannot create that missing path... :)
