Raphael - USB Host?

I am wondering whether or not the Raphael has USB Host functionality? I read this on some internet sites, but searching the Wiki and other avaliable informative websites couldn't bring light to this issue. I know that HTCs ExtUSB only is a proprietary connector, enhancing the USB Port with audio and video functionality. This is not what I'm talking about!
Host USB allows devices to act as an USB host (like a computer) and as such access USB-Devices like harddrives or USB sticks, which is more than convinient. As some other Pocket PC have it, I'm hoping deeply my future playmate has it also.
Maybe some of the lucky users could verify?
Thanks!

Doesn't look like it'll have any host facility no. The only HTC device ive seen with host are the bigger HTC Advantage's which have a normal USB port. I dont think the Qualcomm chipset offers USB host either.

This would be a nice thing to have...
I am still owner of a PocketLoox 720 which is capable of accessing USB sticks and USB HD.

It'd be nice. But I guess it would eat the battery.
I think I saw somewhere a USB bluetooth thingy that enables you to read USB sticks via Bluetooth.

well to be precise both the diamond and raphael have some interesting host ability - in SPL you can set usb host to read NBH file off usb. however you need the right adapter cable, so I haven't tried that yet on the diamond (and no raphael yet).

What an interesting feature... Maybe it's for service centres to unbrick warranty returns easily?

mm, thought it plugged in the other port on the athena...because it also handles vga out (the 4 in 1 cable). and this other port (beside the miniusb sync port) has the icons vga out and usb host.
that is clearly not the same socket as the miniusb (i.e. the sync port).
the diamond & raphael unfortunately only have this miniusb (which is for the sync on athena).

You're right - It's been so long since I used the USB host on the Athena I'd forgotten which port it uses.
Back to the drawing board on that one I guess.

yeah, I also have the 4 in 1 somewhere in the drawer
I only got it to have all cool accessories for my Athena.
anyway, I'll update the thread if I find out more about the cable needed for diamond/raphael

I read in the Diamond service manual (foeund somewhere on the forum here) about using an USB SD-card reader on the sync port on the Diamond. It is used when servicing the phone to upload firmware and test software to the internal storage.
On the picture it looks just like a normal sd card reader that is plugged into a standard USB port on one of the ends on the cable. it is a Y cable where one end is power, one USB and one mini usb to plug in the phone.
I am just doing some tests on this now. I made a usb cable with mini usb in one end and normal usb in the other end. On the on ememstick I have here in the office nothing happens.I will continue to look into this matter.

holy moses. I got something working here!!!!!!!!!!!!!
I had to rebuild my cable a little bit here to get this working.
The new external USB port is now powered from a 5Volts source. I have cut the 5 volts connection between my Diamond and my USB memory.
I am using a standard USB flash memory which i got at some commercial stuff long time ago.
I formatted the USB stick to FAT32 on my computer first.
The thing I tried was:
downloade a custom firmware.
copied the xxx.nbh file to the flash
renamed it to "DIAMIMG.NBH" Capital letters!!
Started up the phone holding VOLUME DOWN and RIGHT button down while giving the power button a short push.
It fired up the Olimex boot scene and asked me to push power button to confirm flashing.
After that it flashed my phone for about 10 minutes (from the USB flash memory)
So there is NO DOUBT, the Diamond has USB master capabilities!!!!!!!!!!!!!!!
When I am in file explorer I still can't get in contact with the memory.
Anyone that has the USB drivers from som larger HTC device????
Can anyone try to flash a phone with an un signed firmware or a firmware from wrong region on a phone that has the original bootloader using this method?

Does anyone know how to use external memory by usb hosting

heh, you were faster at building the cable congrats.
btw, what special modifications did you need to make? just the 5V source?
anyway, this just confirms what i found in bootloader disassembly then.
not sure on the availability of usb host drivers. maybe we will need to implement it ourselves
and sorry, but i do not understand the question about flashing unsigned stuff. the stock bootloader will not accept unsigned NBH, no matter where it comes from, sorry to disappoint you.
EDIT: I downloaded the service manual now, thanks. wasn't aware this was out in the open
anyway, the text mentions you must plug in AC power for the USB host. what a shame.

Just an idea, have you tried to start WM5torage on Diamond ?
It lists the MovieNAND and the system partition. OK, you can't take access to it, but maybe WM5torage recognizes the USB stick from OS.
If it does, maybe a modified version of WM5torage can do these job ?
For short test download here:
WM5torage
Ok, WM5torage isn't the right way to test the access from OS, because it needs at last a running driver.
Qualcomm was running Oxford Semiconductor solutions, maybe the integrated USB OTG is a license from this company ?
@cmonex:
Is it possible to adapt the integrated bootloader driver to WM ?

USB drive is HTC supported

Sorry to dissapoint you, but this is just the other way arround. This enables you to use your phone as a flash drive from a PC. In this thread they want to access a flash drive (USB stick/HD etc) from their phone

SD"2" Mount Issue

My first thread that I can call my own.
Question for you all. Is there an easier way to transfer files over the the GTAB then having to pop out the SD Card and put it into an adapter and then into the computer and then out of the computer, out of the adapter and back in the GTAB?
Because every time I mount the USB, it only mounts the "internal" SD Card. Is there some sort of way to get it to mount both the internal and external SD Card?
I hate messing with the external SD Card. All the "popping in and out" makes me nervous.
I even tried mounting the internal SD Card and then copying the movies/music/etc.. over to the external SD Card via a file manager... but that is DAMNNNNN slow.

I haven't found a way (yet). Given that neither the zPad or TnT stock builds work, I'm thinking it's not that easy to do. Drives me nuts as well because I really don't want to keep taking the card out over and over and potentially damage it, over time.

That's exactly what I am worried about. LOL
I can just picture not paying 100% attention and snapping the card in half or, breaking the "locking" mechanism that holds the card in place.

If you have ADB, can you do adb pull or push?
Jim

My workaround has been to use the LAN tab in ES File Explorer to copy data wirelessly to sdcard2. Probably not the speediest method but it keeps the card in place.

The techie/hacker solution to easy file transfer is to use the Rsync for Android app in the market store. Once you have it setup, (not the easiest thing to do) it works great for moving files automated from your gtab back to an rsync server (my linux box to the rescue). I even have a secondary profile to get it to reverse rsync a specified directory FROM my linux box to my gtab. Presto -- easy file transfer via wifi!!!

Also, another idea might be to use Dropbox?

Hi,
You all got me curious, so I just tried the following:
- Created a dir under /mnt/sdcard, /mnt/sdcard/mymnt
- Get temp root (z4root)
- Start terminal
- su
- mount -t vfat /dev/block/vold/179:17 /mnt/sdcard/mymnt
At this point, I can access the sdcard2 by using /mnt/sdcard/mymnt or simply /sdcard/mymnt.
So, I disabled USB debugging, and I get the popup asking if I want to activate USB transfer (I'm on 3452, on earlier TNT firmware, it use to say enable USB storage).
I click the button to Activate, and then another window pops up, and I click Activate.
Then, the popup just stays there, with the spinning thing. It never enables USB transfer, and, on my PC, I see the removable drive, but when I click on it, it says it's not ready.
I've also tried umounting /mnt/sdcard2, thinking that it might be confused because of the two mounts to /dev/block/vold/179:17, but it still does the same thing.
So:
- It looks like I can mount the /dev/block/vold/179:17 (the external microSD card) under /mnt/sdcard, and
- When I do that mount, I can see the contents of the external microSD card in terminal under /mnt/sdcard/mymnt and under /sdcard/mymnt, but
- For some reason, turning off USB debugging/activatiing USB transfer fails.
Maybe someone can figure out why activating the USB transfer fails. If we can figure that out, then that would allow seeing the external microSD card via the PC USB interface.
Jim

I think it would need to mount both volumes -- the internal SDcard and the external SDCARD2 -- separately...
Using a mount (reparse) works internally since they are on the same device -- but if you try to mount SDCARD externally it doesn't understand the reference to SDCARD2
My phone actually mounts to the computer as two drives -- one for internal (SDCARD) and the other for external (SDCARD2)
I'd assume there is a way to have something similar work on our gTablets...
I'll have to slap a spare microSD card into the tablet to try though...wondering if teh INF needs to be tweaked as well (??)

From what Ive seen or experienced, Cyanogen was the only rom that Had the Sd card and Sd card2 Thing fixed right (with exception of having to plug in the Power cord before mounting). Evrey other Rom seems to have problems. But Cyanogen has way too many other problems so I use Vegan since to me it seems the most stable :s

Yeah -- my phone is running a fork from Cyanogenmod 6...so the code is shared

That's the problem... When the Gtab is plugged into the PC USB (while USB debug is disabled), only one new "drive" appears, corresponding to /sdcard on the Gtab. There is no 2nd drive appearing on the PC corresponding to /sdcard2 on the Gtab.
I've been looking at my Windows configuration, with the Gtab plugged in, and the one drive that appears shows up under "Portable Devices" branch in Device Manager. The properties show that it corresponds to "wpdfs.inf", and looking through that, it looks like a generic USB Mass Storage configuration, i.e., a USB drive.
I still think that something would need to be fixed on the Gtab end for the two drives to appear on the Windows end.
Jim

app fix
I have found a workaround for the issue with the installation of a single app:
http://forum.xda-developers.com/showpost.php?p=12299831&postcount=2

Depending on what you want to do, an FTP solution is also possible as discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=869844
By using swiFTP, I am able to open a connection through a Win7 windows explorer, and I can drag-and-drop files to SDCARD2 (over a wireless connection). I put a 1Gig movie on the card and it took about 12 minutes.

Another option is to use Multi Mount SD-Card. This is link is for the lite version, there is also a paid version.
This app works outside the embedded SD Card Mounting scheme that comes with Froyo.
With this you dont have to press the "Mount USB" button that comes up in the notification bar when you attach the USB cable. Instead it will auto-mount the either the internal or the external SD Card when you plug in the cable.
(Having configured the setting of your choice before hand).
Unfortunately it can not mount both at the same time.
It works with my GTAB and I'm using VEGAn 5.1 Beta.
(Without the 5.1.1 Suppliment patch)

Folks are still struggling with this?
Use a USB flash drive, I do it all the time. Just a regular, boring, Windows FAT-formatted flash drive.

Wow it is amazing that this problem still exists.
I am a new owner of a Gtab and have had it for less than 2 days. Thank goodness for the many informative posts on this site, that have helped me make my new toy almost perfect.
I updated to 3588, installed cwm and titanbackup, vegan5.1.1 including the suppl patch and even learned how to tether it to my Samsung Captivate. The one thing that was annoying me was my device not seeing the 16 gb microsd card that I had inserted both in the gtab and on my pc.
After reading this thread, it looks like I am not going crazy, but it seems like my device is destined to not acknowledge this addtional storage in it's settings?
I really was hoping to use the external card for videos and my mp3 collection, so I am missing something or did I do something wrong to make this happen?
I would appreciate any comments or suggestions since this is the only thing that I need to get squared away before I install more apps(with the possibility and ever present threat of having to re-install something I may have already done)
I could not post this question in the dev section since I do not have enough posts to allow me to.
Thanks
Tina

[Q] External USB HDD Support

Does Someone has successfully attached an external usb disk to the gtab using Vegan Beta 5? Is not working for me, not even recognized. It is formatted on Fat32 and my Archos 101 see it. Any suggestions???

Hi,
I have been using my external Western Digital usb 500gb disk with gtab. I am on Vegan 5.1.
The first time i hooked it up, it did not work. Gtab did not see the usb hdd and usbdisk did not show anything at all. I tried it couple of times in vain,
Then i powered down the gtab, unplugged the usb hdd and restarted the gtab. After gtab booted up i gave it some more time before touching the tab. Then i hooked up the usb hdd and allowed gtab to scan / read the usb hdd. I took a while ( maybe based on amount of data you have in usb hdd) and then i when to file manager, usbdisk and i could access all my files on usb hdd. it is fat32 formatted.
Try couple of time and allow gtabl to read through all the files . I will work.
Let me know if that helped.

That didn't work either... will try CM6 Rom to see if can detected the usb hdd.

Hasn't worked for me either. I have a FAT32 USB hard drive that never shows up under usbdisk. I am running Vega-Tab b5.1 and the USB port is working; my evidence is a working USB keyboard, and a green light on the hard drive indicating it is connected. I will try again but so far nothing.

For those of you for whom this doesn't work: I wonder if maybe there's more than just a single FAT32 partition on the hard drive? Maybe there's a hidden partition that might not be normally visible?

How would one check for this? (Using WinXP)

worked for me
I think you have to have a FAT32 format to get the drive recognized. I had a 100GB thin, portable drive and it worked just fine. It shows up as /usbdrive. This worked before the latest update of the base OS and still works for me.

You can try to go to Computer Management==>Disk Management to see what shows up there for the USB drive, but, that might now show some weird partition types. It would show the unallocated space but not the unknown partition type.
Or, try to go here:
http://www.terabyteunlimited.com/downloads-free-software.htm
and download "Partinfo" and run that, and see what that says. That dumps out a bunch of info on partitions on the drives that your machine sees.

As has been mentioned in other posts, for the drive to work, it appears that you'd need to have only a single FAT32-formatted partition on the drive. If either Disk Management or Partinfo show that there's more than that, then that may be why the Gtab can't see or mount the USB drive to /usbdisk.
Just guessing here...
Jim

I just get rid of the hidden partition, and now is a single fat32 partition. Will check and write back with results.

It sounds like you did find a hidden partition on your drive? If that's the case, was at the beginning of the drive, or somewhere else (at the end)?
I'm kind of assuming that the Gtab may only be able to see a FAT32 partition that starts at the beginning of the drive, but not 100% sure about that.

This particular drive only has one partition and uses FAT32 format. It is an 80GB drive (and nearly full). My other portable drive uses NTFS. The FAT32 drive says it is "healthy, active, primary partition" under "Disk Management". The graphic (Windows 7 PC, I am at home now), shows only one partition where as my "C" drive shows three separate partitions: one 30MB, one 14.65 GB and one 916.83GB.
Still scratching my head. No big deal as long as I have an internet connection and upnplay capabilities.

Copy from one USB-device to another with Asus Infinity

Hello,
New to Android and new to this forum. I have my TF700T two weeks now and I'm glad I bought it. My target is to copy the content of my Compact Flash cards (16GB each - from my DSLR) to a portable hard drive. Therefore I tried to connect both a card reader and a portable hard drive via an auto-powered USB-hub to the only usb-connection of my tablet. I even tried with another hub and even with a third hub. The only result was that my tablet only found the first device that was connected (regardless wich one: the CF-card or the HD) with the hub and not both at the same time, so copying from the CF-card to the drive isn't possible in one step. Sure I can copy the CF-card to the internal memory of the tablet and in a second pass move it to the HD, but that is very time-consuming.
Anyone who knows how to connect more then one usb-device at the same time via a powered USB-hub and do a file transfer between them? Your help is greatly appriciated.

You can use wi fi transfer to do it with a file manager, like file expert.

@tbtaf: When on vacation or on a photo trip I only have that portable hd, my tablet and a powered usb hub. I think a Wifi appraoch is not applicable then. Or am I missing something?

Sounds like you need to setup a second mount point for the additional device - don't know if that can actually be done or not, but I do know that some people who could not even connect the first device were able to manually specify the device by mounting it in a terminal window.
I'm not sure 100% on the code, but let me try to find out.

Or you could copy the 16 Gb CF card onto the pad's internal memory (or external MicroSD card), disconnect it, connect the HD and then copy it out again.

He already mentioned, he doesn't want to do this, he wants to copy straight.
For now, it's not possible since the powered hub or non power hub unable to recognize 2 devices at the same time.

CF, now there's nostalgia if anything. I thought those became outdated over 3 years ago... Fact is the CF is hardly compatible with mobile devices these days.
No, you can't copy from an external cardreader directly onto an external HDD through your tablet. It can only read 1 storage device in the USB port. Multiple devices works, but multiple storages doesn't. Some people have had some success with USB Flashdrives/Pendrives instead of HDD's though. You could try that.
You can copy from an SD to HDD easily though, so you could consider using an SD with a CF adapter if your camera has no SD slot. (SD's have the added advantage that the pins can't bent.)

Mount two USB drive

Hi,
When I connect my one to hub with an OTG cable and put a usb hdd on it the harde drive is mounted and everything is perfect.
When I plug a second USB drive, it is not mounted.
I made the same experience on my Samsung Galaxy and it works fine, I see the two drives mounted on the phone.
Any idea to make it work ? Yours.

Is the hard drive sufficiently powered?

Hi,
Yes it is. The usb hub I use is powered with an external power source. The other point is that when I plug the disk alone, the phone mount it, but when I connect the flash drive, the phone try to do something, but at the end, onyl the first connected is online. If I connect the flash drive first, and then the hard drive, only the flash drive is mounted
