Hi Peter,
[...]
It needs to check your hardware, it is probably there is a high capacitance
at vbus pin. Besides, the vbus should be lower than 0.8v if it is
disconnected from pc.
I just wonder why I can no longer use device mode only after I plug in the
adaptor for host device. Before

Hi Peter,

Two possible reasons:
1. You have not gpio control for vbus toggle when role switches.
This works well.
2. Your hardware has some problems that the vbus can't lower than 0.8v.
How can I check that?
Just measure the voltage of
You should see the voltage of vbus pin is less than 0.8v when
nothing is connected, we use B_SESSION_VALID (0.8v) to judge
it is connected or not.
You get 2.25 all the time or it is discharged very slowly?
On my mx28evk it discharges very very slowly. Any hints about it?

- I use the port in HOST mode by plugging in a USB pendrive over the OTG-
capable
reduction ; this works OK
- I disconnect the reduction and connect it to the computer ; here I get
timeout waiting for 0800 in 11.
This means the BSV bit in OTGSC register wasn't unset.

No, I don't have this one available right now. I tried both MX23

Note that both have working USB peripheral mode

One patch e.g. adds an delayed worker to handle the otg events. Another
