What about OTG, Is it not supported? The constant
(OTG_STATE_B_HOST) will always evaluate to true.
OTG is not supported and never has until now due to missing drivers.
try to make a statement rather than encapsulating what you are trying
to say in a question please, because i still don't get what
you mean with needs work
Note: For the M2M, the vendor disabled the USB DEV (by setting the
reset signal in the boot loader). They did this probably to save
power (this unit has a battery). And unfortunately: if the USB DEV
reset bit is not cleared, then the connected USB device on the USB
HOST (of the ramips) is not detected.

Since, I was asking/wondered how OTG is/was supposed to work at all ATM. However: OTG is not supported and never has until now due to missing drivers. So, this is all fine then.

Re: [OpenWrt-Devel] AsiaRF AWM002 (ramips) USB and reboot broken at r44044
Dear Sir.
the fe_reset only used to reset ethernet and switch driver.
i think your problem is the old code is wrong.
at ethernet driver(soc_rt305x.c) it just clean all reset bit (enable all
functions. usb?).
but the new code only reset and enable ethernet and switch block.
you can see the diff as below.
static void rt5350_fe_reset(void)
{
- rt_sysc_w32(RT305X_RESET_FE | RT305X_RESET_ESW,
SYSC_REG_RESET_CTRL);
- rt_sysc_w32(0, SYSC_REG_RESET_CTRL);
+ fe_reset(RT305X_RESET_FE | RT305X_RESET_ESW);
}
+void fe_reset(u32 reset_bits)
+{
+ u32 t;
+
+ t = rt_sysc_r32(SYSC_REG_RSTCTRL);
+ t |= reset_bits;
+ rt_sysc_w32(t , SYSC_REG_RSTCTRL);
+ udelay(10);
+
+ t = ~reset_bits;
+ rt_sysc_w32(t, SYSC_REG_RSTCTRL);
+ udelay(10);
+}
Best Regards.

I bisected the problem. It appears the bad commit is r44044 (r44043 is
good). The reset and usb problems appear at the same commit.
