Hello
I've made an Android application that takes some measurements from custom made device. We decide to use FTDI chip for usb serial converter. The application works fine and communicate with attached device. But on some phones/tablets it doesn't work in sense that Android device does not recognize attached device over OTG. I made tests from version 4.0.4 to 4.1.2 with different device so I think that it is not problem in OS.
Is there any way how to detect if phone or tablet can recognize and establish communication with device based on FTDI?

Hi there,
I'm looking for some information about what i would need to do to get a USB device recognised on my x7501. I'm looking to connect a USB-to-UART bridge chip (FT232RL or something) to the device so I can essentially have a serial/COM port on my phone, which i can use for data logging.
I was wondering if anyone's had experience with anything like this so i could find out:
A) what devices are already supported in WM6, as the bridge chips can mimic a virtual com port via built in windows drivers but im not sure if this driver is in windows mobile
B) what i would need to do to setup for dev for writing WM software and the driver if necessary (i have visual studio, i think there is a WM emulator but im not sure totally?)
C) any other questions you think are relevant to my goal
thanks in advance,
sebastian
Hi
Has anyone heard something about PXE booting from Shift PC, or how to com in the Bios. We want build the Shift PC automatic with OS Deployment Tool.
Thanks for all the info.

PXE boot is not possible - remember, the Ethernet port is not embedded, but just an USB attached device. Of course, you could create an bootable USB stick that provides a kind of USB support, assuming the necessary drivers for the ethernet port in the USB Hub are available (but in fact, i really doubt so).
OK Thanks i will try it
HI,
I am trying to interface the UVC Camera to the Samsung Galaxy Tab 10.1(GT-7510) , but I am not able to see the device node getting created in the shell( I have installed the Linux terminal Shell Application) and rooted the device using this Video .Can somebody plz tell/advice how I can achieve it and access the device Node or at-least get it created.
Following is the log on dmesg :
usb 1-1 new high speed USB device using tegra-ehci and address 97
hub 1-0:1.0 unable to enumerate USB device on port 1 ,
usb 1-1:device v0ac8 p3420 is not supported
On My Laptop I get this output on Dmesg :
[12307.364237] uvcvideo: Found UVC 1.00 device Venus USB2.0 Camera (0ac8:3420)
[12307.366108] input: Venus USB2.0 Camera as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1/2-1.1:1.0/input/input14
[12308.537059] usbcore: registered new interface driver snd-usb-audio
also i can see the camera getting blinked on connection which proves that it is getting the power-supply and getting connected with the system.
I think there is a support for UVC USB devices in the kernel (not sure) otherwise I am ready with the Kernel For Samsung Tab 10.1 (GT-7500 (Higher Version: GT-7510)) from here .(GT-P7500_MEA_Opensource.zip (requires Login).
Plz assist.

You seem to know a bit about what you're doing. I'm not really familiar with this device. I did a search and did not find anyone who has don't this yet. The first priority is to get a Linux device in /dev/ folder. This is generally handled by a device driver and a udev rule. Try the newer kernel if you can. The android 4.0 ics has a Linux 3.x kernel. See if switching to ics helps. Try compiling a custom kernel with all modules. Once you have a device, try using SSH or sftp from your desktop under Linux to stream from that device with vlc or another media player.
Do you have any examples of this device in use on mobile Linux? It may require writing an entire kernel driver.
HI,
Yes that is the same line of thinking for us as well.We are trying to compile the kernel and load it .- Ongoing
I believe only the zImage is the one which is to be flashed.But I am little scared to do this.Couldn't find the instructions to loading the Zimage even though I can compile one.

Flash it with Heimdall, even if it won't work you will be still able to get into download mode of bootloader (which you aren't supposed to flash) and reflash the kernel with stock one.
Hi.
I have Coolech 1FA-09D based board with Hisilicon Hi3716C chip on it. It's android based media player. Full system flash was performed on the device, but firmware flashed was wrong, so device is now useless.
It stops at boot screen (not android, but bootloader). On device I have 2 available usb ports, but I asume those are host ports, not to be connected to PC. On PCB I have 4 pin connector, but don't know what kind of connector that is. At the moment I have no documentation for the box.
Company that I got box from will provide me original firmware, but how I'm going to flash it? Any ideas? Fastboot as far as I know works only with usb connected devices. ADB can't connect to device trough lan cause no adb server is running on the other side (box get's its own IP address and does some other initialisation which includes usb ports and then freezes).
The 4 pin connector is a serial console, but be carefull, its 3,3V logic and not RS232! So you need a level converter or usb ttl converter cable like for a old cellphone or something. Then within uboot you could load the firmware from tftp or upload it with xmodem.
Could you please send me the firmware? I would be very interested in it . (Or just upload it somewhere like filesonic)
Thanks.

Thanx for your answer.
About the firmware, sorry, I can not send it to you and there are two reasons for that:
I don't have the firmware yet. When I get it, I'm not allowed to distribute it. You can find kernel source code of similar device (A.C.Ryan android based box) on their web page. Their device is also based on Hi3716c.
Hi,
Yes, I am using a acryan box clone and wanted to check out the features of the Coolech firmware on my box. That was the reason I asked about it. But okay, if you can't share it, its fine.
Hi,
I have just picked up a Note 3 on Three UK.
Am I right in assuming that the wireless chipset BCM4339 which is the same as on the Nexus 5 is still not able to use bcmon mode to allow us to enable monitor mode?
Would a specific ROM be necessary to allow a TP-Link WN722n (RT2800usb) to work on OTG cable?
I have tried both bcmon on my note 3 and also my TP-Link via USB OTG cable and neither have had any results.
Thanks
Toby
I've installed USB Host Check to confirm that USB host support is enabled on my note 3.
(android.hardware.usb.host.xml OK)
(handheld_core_hardware.xml OK)
I then installed USB Host Controller.
Both devices recognised but obviously not working. (Atheros USB 2.0 WLAN for TP-WN772n) and (ASIX Elec Corp AX88x72A) for USB ethernet.
When I run USB Host Controller I get the following error message:
"s3c usb host driver not found".
Another member on XDA posted a link to the Halaszk Kernel on the N9000 apparantly having OTG USB host support for S3C

I'm still hitting a brick wall on this one search wise.
Would stil love to be able to use my WN722N on my Note 3.
Has anyone any experience in modifying the Kernel Module to allow the ath9k to work on Note 3?
Getting a wireless adapter to work on Ubuntu or any form of Linux can be difficult if the manufacturer doesn't provide direct driver support or at the very least a "Tar" which would allow an end user (with sufficient skill) to compile the drivers them self. My understanding of this is limited but from what I can remember Android is JavaScript VM running on a Linux kernel. So you need the Linux source code for the driver which usually comes in a "Tar". Feel free to correct me if I am wrong.
