Step by step guide to USB Host

[Guest r8zer]

I like connectbot but any termnal will do. I havent installed the host mode to test, but if someone wants to try to script this then fair enough. I was really just pointing people in the general diretion

right just tried it, and it will not unmount says not found.

right i tried

umount /mnt/usb/system_usb = failed

umount /usb/system_usb = failed

Odd. I wonder if dmesg shows anything useful? Do you have any applications running which may block the umount. Perhaps a sync would help prior to umount? If you cant unmount it, Id power down before removing the drive.

you cannot sync with pc if thats what you mean as it will not work in host mode, and i have nothing blocking the unmount.

in host mode holdiing the home key brings up the most recent list.

weird looks like it only does that if something is not responding.

No sync is a shell command but I doubt it will help. Ive just tried to umount my sdcard and that failed too which is odd. My only other suggestion is to shut down before pulling the card

yer, thats what i was thinking oh well, something will come up.

[Guest remlap]

Also when in software power down when USB Key it powers off then comes back with a dim light very odd, suggest doing a hardware long press shutdown.

Finally got this bigger to work!

Typing this from saitek. Eclipse (backlit) keyboard

my only advice would be that even if get to

1200KB/s (0 bytes in 787448.000s)

and you think nothing has happened. Carry on - it probably worked!

(I was hung at this point for ages, reinstalling the drivers over and over cos i didn't think it had worked - but it had!)

Persevere!

Now on to the testing... :)

I know exactly how you feel, however . . . . . . I got the same "0 bytes in 787448.000s", but then carried on with the second command line and it's all working. All steps after worked like a dream.

Don't give up, I persevered and the people here do help.

Thanks Steve and to everyone else, I was getting to hung up on the 0 bytes thinking it hadn't worked when in fact it had so alright here now.

Tested a Freecom usb stick which worked fine.

Tested a iomega 250gig 2.5in external that works when the vega is plugged into power but not when it is just running from the battery.

Hey,

pretty awesome stuff, however i can't get it to work, I get a message telling me that AdbWinApi.dll is missing from the computer.

Edited December 19, 2010 by Drizz

[Guest Drizz]

OK Update and more info.

I looked in the r5 folder and found AdbWinApi.dll and copied that over to the c:\android folder.

Did the whole cd c:\android and dir thing. Listed the adb.exe and flash_image as well as the AdbWinApi.dll.

adb devices = "List of Devices attached" (is it supposed to list anything?)

I then started step 5.

and this is where I hit a problem, the "adb push flash_image /data/local/" cmd returns "error: device not found"

Had same problem you need to copy that .DLL file to the same folder as your ADB program and retry

Oops sorry just saw you had got over that one. :)

You need to have Vega connected by USB to PC with debug set then a number should appear in your list devices response..... oh and with power lead connected to Vega

[Guest bazzlad]

Congrats everyone on getting it working - I've edited the main post to include the dll file too.

[Guest Drizz]

Still not working, I can only think I'm missing something or Win 7 is blocking the vega from being visible.

Heres how far I get:

Tried this today and didn't work.

Selected the USB Host GScript and when rebooted the only thing I had on the screen was

Starting fastboot USB download protocol. and nothing else.

Plugged in USB to PC (XP) and it recognized the Vega as a device but couldn't do anything.

Managed to find some information about fastboot Here and here

Extracted the contents of the 1.06.5 image to a folder (run the exe without the vega plugged in and it will show you the path where the contents of the exe file were extracted to. e.g. c:\docume~1\Mark\locals~1\Temp)

Then managed to restore the boot image from the extracted exe and reboot using command below

fastboot flash boot boot.img

fastboot reboot

Haven't lost any applications or settings as far as I can tell.

I may/may not try running the Gscript again later after I've backed up all apps

(I have R5 custom ROM with performance pack and Clockwork mod)

UPDATE

tried running the USB Host GScript again and noticed there was an error I didn't notice last time

stderr: mtd: not writing bad block at 0x00600000

flashing boot from /mnt/sdcard/USB/host.img

error writing boot

so just ran the USB Slave script, which runs with no errors, rebooted and all OK.

Will need to run through the steps again later making sure I don't miss any.

Help. Follow the guide. Ran Host script from Gscript. Restarted Vega. And nothing....it won't reboot. :) I have tried the steps in the Bricked Vega thread but no joy. Any suggestions pleeeeaaaase.

[Guest trevor432990]

Drizz from the readout you published it looks like your Vega is not connecting to the PC correctly. Can you confirm that you have the Vega turned on, USB debugging switched on at the Vega, and the USB and power cable both connected? If so can you go to your PC Windows control panel and check SYSTEM>HARDWARE>DEVICE and tell us what it thinks your Vega is or better still do a CTRL & Prt.Screen and paste the screenshot into you reply posting. We will get it sorted in the end I'm sure. :)

It's better if you start a new topic for this mate else it'll get mixed up with everything else here. Cheers

[Guest Drizz]

OK here's a screen grab. The Vega appears in devices and printers as nVidia Harmony and in device manager as Android phone and nVidia Tegra 2 USB device.

[Guest warriorscot]

Should also appear as a USB device that is where some people trip up. Easiest way to find it is to disconnect and reconnect the vega.

Also in an unrelated note how many programs can you have pinned to a taskbar before it becomes silly.

[Guest Gregga]

stuck on stage 7

open up gscript but nothing happes - just a blank screen
