Dears,
I am trying to let my Blade support USB storage(support U-disk).
I know Blade using Quamcom MSM 72K SoC, which include an OTG IP core in this SoC;
also I rebuild linux kernel with build in USB OTG feature.
I plug U-disk into my Blade by OTG cable. And notice DMESG have following response. and There is /proc/bus/usb/001/001 file when the usb plugin, but soon disappeard. But I did not see any device file generated in /dev folder.
Here is the message, and I will continue update this post with my findings, hopeing get some help from you.
thanks !

From above article, it seems B-device (U-disk) did not signal its connection, which cause a_wait_bcon_tmr timeout and goto a_wait_vfall state and finally to a_idle state.
It has the same scenario with the USB-mouse.

Check Blade as peripharials states transactions.

obviously, Blade is regarded as B-device, from b_idle -> b_sess_vld -> b_periparial.

It seems that the U-disk, does not signal its connections, which cause A-device(Blade) can not goto A_host state.
Does any body know how to make the U-disk to signal its connection?

It seems D+ is used by peripheral to signal its connection. how to debug this?

I doubt it is 5v power is not supply by Blade, So I use external 5v power and get b_conn signal:
