Hi Steve,
Sorry, let my explain my trouble. My ADB works well before I modprobe
usbserial, see below messages.
cat /sys/kernel/debug/usb/devices
....

On my host, I have the file 51-android.rules located at /etc/udev/
rules.d/ includes two lines.
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="0489", MODE="0666"
SUBSYSTEM=="cdc_acm", SYSFS{idVendor}=="0489", MODE="0666"
I expect the ACM serial (ACM0) can be recognized after enable
CONFIG_USB_ANDROID_ACM on android side.
Correct messages like,
I:* If#= 1 Alt= 0 #EPs= 1 Cls=02(comm.) Sub=02 Prot=01
Driver=cdc_acm // acm is supported
E: Ad=83(I) Atr=03(Int.) MxPS= 10 Ivl=32ms
I:* If#= 2 Alt= 0 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00
Driver=cdc_acm // acm is supported
E: Ad=82(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
Do you have idea about why host fails to load acm driver on host?
thanks,
chihchia
