USB pen drive not auto mounted / unmounted in imx6 kitkat

Sub :- USB pen drive not auto mounted / unmounted in imx6 kitkat
Dear Sir,

we have developed a custom board using imx6DL processor.

We have developed android kitkat 4.4.2 for this board.

When we are connecting usb pen drive then in dmesg it is shown as sda.

But it is not get mounted anywhere. If we manually mount it then we can see contents of pen drive.

If we remove pen drive and again connected then in dmesg sdb shown.

Means every time pen drive connected new node created for pen drive in /dev/block/ and we have to manually mount it.

Also in Android setting -- storage -- usb storage it is not reflected even after mounting it manually.

Please give some solution for this problem..

Dear Artur,

Thanks for your reply.

I have checked it with box USB host and usb OTG port. I am getting same response.

When usb pen drive connected --- it is detected as /dev/block/sda ----- but not mounted

If we remove pen drive that also detected sda get removed from /dev/block.

IF we manually mounted then we have to manually unmount it. Otherwise second time it will detected as /dev/block/sdb.

Driver loaded for this pen drive is usb_storage.

In our kitkat 4.4.2 we are missing something because of auto mounting and unmounting of usb pen drive in Host as well as OTG not working.

If you can provide some check points, it will be helpful for us.

I have checked it on my i.MX6Q SABRE SD board with the original KK4.4.2 BSP by NXP/FSL - everything works fine, i.e. an USB storage device is always detected as sda, auto-mounted and becomes visible in the Android Settings - > Storage menu. So, the problem is specific for your custom system, either in hardware or in software. By the way, what USB port do you use, OTG or Host?

Have a great day,
Artur
