I am developing an Android application in which I have to communicate
to an USB device. I tried to use standart google API in my app, but
list of devices is allways empty.
Same things if i use USB device info with google api. List of devices
searched by google api is empty,
lsusb gives following results:
Bus 001 Device 001: ID 1d6b:0001
Bus 002 Device 001: ID 1d6b:0002
Bus 003 Device 001: ID 1d6b:0001
Bus 002 Device 002: ID 2226:0014
my device is 2226:0014
log of eclipse:
I/USB3G(92): event { 'add', '/devices/platform/sw-ehci.1/usb2/2-1',
'usb', '', 189, 133 }
I/USB3G(92): path : '/sys/devices/platform/sw-ehci.1/usb2/2-1'
I/USB3G(92): VID :size 5,vid_path '/sys/devices/platform/sw-ehci.1/
usb2/2-1/idVendor',VID '2226
I/USB3G(92): '.
I/USB3G(92): PID :size 5,Pid_path '/sys/devices/platform/sw-ehci.1/
usb2/2-1/idProduct',PID '0014
I/USB3G(92): '.
I/USB3G(92): cmd=/system/etc/usb_modeswitch.sh /system/etc/
usb_modeswitch.d/2226_0014 &,
I/USB3G(92): excute ret : 0,err:No such file or directory
If i plug in devices like rs232 adapters, bluetooth dongle, nothing
happens,and there is no any result from API and lsusb.
Prtocol of a device is based on ezusb library. Android v.: 4.0.3
kernel v.: 3.0.8 firmware build: crane_evb-eng 4.0.3 IMLK74k 20120330
Is there are any way to access hidden USB devices via API?
