Adb is not connecting to Android device over USB

fhardy · June 4, 2019, 8:58pm

Trying to debub Android modem from OpenWrt router using attached with no success. Built in put it is not connecting. Does not see android device. Interesting thing is I can connect to the android device IF connected from Ubuntu PC first, then hot swapped to the router

Anyone ever tried to use from OpenWrt? Are there tricks...

Something seems strange... You're connecting to the phone from a linux PC over IP, not USB...

It seems like something is wrong (in general) with ABD-over-usb connectivity...

I'm a bit rusty but I'm 90% certain ADB does not use any of the ttys, it's a custom protocol and the adb tools use libusb. (As I said, it's been a while).

It's also strange that your phone is enumerating THAT many serial devices...

anon50098793 · June 5, 2019, 2:26pm

just tested on openwrt@master in x86 vbox

adb usb works fine.....

Just showing the interfaces as proof of electronic connection.
The only way to connect to the device is to first do a usb/tcpip/connect from the PC. Then do a connect from the router. Only way I can get adb on the router to see android device
The Android is a modem that has many different data and debug ports. That's why some many tty's enumerated...

Can you tell me which USB drivers are instantiated in your build?

Thanks

I don't know why the PC connection is helping you, but:
The adb utilities have a specific list of USB VID/PID pairs that are "supported". Some oddball devices don't use standard VIDs/PIDs and have to have those added to a config file somewhere. I don't remember the details.

fhardy · June 24, 2019, 7:59pm

It turned out adb/usb_linux.c needed a patch to correctly handle USB3.0 message headers. The reason is worked when I used the PC was the PC uses USB2.0. Once connected messages did not have the unsupported header... lol. Here's the patch...

If you've got the energy, posting the patch to the openwrt-devel mailing list might benefit others.

I'm a noob, what is the full openwrt-devel mailing list address?

Thanks bro! It resolve my issue when connect to Android phone using USB3.0.
