Re: [android-developers] Re: Android 3.1 and USB to Serial
Updating to a new version of Android from the carrier may include a new kernel. However, I tried it with a version of 3.2 and it didn't work. My guess is we may have to wait for 4.0. However I did get a Galaxy Tab 7 Plus, and it has the necessary parts for USB hosting. -Taylor On Fri, Jan 6, 2012 at 2:32 AM, s.rawat imsaurabhra...@gmail.com wrote: Note that the Samsung Galaxy Tab 10.1 (as of the 3.1 update - trying 3.2 now) lacked some component of the USB structure that allowed random devices to be enumerated. You are correct ! Do you feel that updating the Android rather than Kernel will do the work.I have Acer iconia A501 and its pretty good in responding to external USB devices even UVC compliant USB devices.

Re: [android-developers] Re: Android 3.1 and USB to Serial
We have successively implemented an app that talks directly to an FTDI chip over USB on an Android 3.1 Tablet (Acer A500) using this code: http://android.serverbox.ch/?p=370 Note that the Samsung Galaxy Tab 10.1 (as of the 3.1 update - trying 3.2 now) lacked some component of the USB structure that allowed random devices to be enumerated. The OS sees a mouse, keyboard, hub, and mass storage device, but everything else it is supposed to expose to apps using the new APIs. A simple test app that shows all USB devices works great on the Acer but fails to show anything on the Galaxy Tab 10.1 with the 3.1 update. Good luck. I only saw this message by accident as I never check this anymore, so if you ask a question and I don't respond, shoot me a reminder direct and I'll check the mailing list message and respond there (so everyone can still see). -Taylor On Tue, Nov 15, 2011 at 4:44 AM, MartyMoose ma...@bruner-consulting.comwrote: Do you think this would help? http://slickdevlabs.com/slick-usb-2-serial-library/ On Nov 14, 9:50 pm, RLScott fixthatpi...@yahoo.com wrote: By the way, our workaround solution was to abandon the USB-serial converter and instead use a Bluetooth-serial module, like the RN-24 from Roving Networks.

I'm curious to know if you were able to get this fixed using Acer Iconia
A500. Are you able to use the android application to enumerate devices
using USB Host API?
Warm Regards,

Hey!
I've actually had the EXACT same problems and it was driving me nuts!
I'm running a 16GB Wifi Galaxy tab with the 3.1 touchwiz update.
I can connect a USB mouse and keyboard and hub all just fine, they
work great. However, when I try to enumerate the devices, I get
nothing.
To compound the confusion, I was trying to build custom kernel drivers
for an unsupported device (FTDI chips) and it was driving me crazy

Hi Anil,
Yes, I did get it working with the Acer. I had replied off list to Will
because my original reply to the list was taking too long to get approved
(it was my first post to this list).
Here is my first off-list message, where I gave some details:

Hey,
I replied to the group, but I'm not seeing the message, so I don't
know if it failed to post, or if its in limbo since I'm a new user.
Anyway, I wanted to reply directly to you. I was having the EXACT same
problem as you. I had a USB device that I had compiled a kernel module
for. I loaded the module onto the tablet, and lsmod showed it running.
However, I couldn't get the device to work, and dmesg showed the same
problem - device not supported, over and over, even though the VID and
PID matched the source code for the driver. I was going crazy, but I
thought it was my kernel modules, so I tried a different approach at
someone's suggestion.
I tried some of google's example code for USB, and when it runs
getDeviceList() I had it print how many USB devices were connected. It
always reads zero, even when a functioning USB mouse is connected!
This was frustrating, so I googled for how to enumerate devices on a
galaxy tab, and found your post.
After seeing your post, I realized this may be an issue with Samsung.
I bought an Acer Iconia Tab A500 today, as some users had reported
success with it - it works! The same code run on the galaxy tab still
fails.
Both are running 3.1.
So I'm inclined to believe this is an issue with Samsung. Did you ever
get this working?
I have had continued success with the Acer, and none with the Samsung.
Will - replying to your off-list message. I just checked again. The Acer
enumerates a webcam and thumbdrive I've tried, but not a mouse or keyboard.
This is with the following code, which logs values to logcat:
UsbManager usbman = (UsbManager) getSystemService(USB_SERVICE);
HashMapString, UsbDevice devlist = usbman.getDeviceList();
IteratorUsbDevice deviter = devlist.values().iterator();
PendingIntent pi = PendingIntent.getBroadcast(this, 0, new Intent(
ACTION_USB_PERMISSION), 0);
while (deviter.hasNext()) {
UsbDevice d = deviter.next();
l(Found device:
+ String.format(%04X:%04X, d.getVendorId(),
d.getProductId())); }
where l is a function that logs stuff to the debug window.
That is a snippet from the source code found here:
http://android.serverbox.ch/?p=370
There is that USB missile launcher that the google demo supports. I have
been considering getting one of those to do some more testing with the
Samsung.

Then I tried this:

and couldn't get it to indicate that ANY devices were enumerated, even
when it was just a USB mouse that was working!
So then I tried BOTH of google's example apps, modifying the code to
print all enumerated devices. Nothing. It printed the count value for
the number of devices enumerated. Zero. Again, this was with a
functioning device plugged in (In this case a keyboard).
Annoyingly, I couldn't even TRY the ADB example the way its intended,
because my phone is apparently a high power device and the tablet
straight up tells you it refuses to mount it. Grrr.
But aside from the high power device issue, which is annoying but
seems to be by design, I am starting to feel like there is some
problem with the USB implementation on the Galaxy Tab 10.1, and I am
going to go out and buy an Acer Iconia A500 since people have reported
success with that, and I am doing this for work.
I will let you know how that goes.
