Re: USB client suspend and resume on PXA270

Tech-Archive recommends: Fix windows errors by optimizing your registry

Dear All,

I'm currently facing the same problem..
USB activesync failed to work after suspend resume cycle

1. cold boot -> plug in USB -> activesync works
2. plug out usb cable -> suspend unit -> resume unit
3. plug in usb cable -> on host PC it showed fail to recognize device

further trace revealed that function "UfnMdd_Notify" was not called as it
was before
the suspend resume cycle.

Anyone has a solution or know what's happening ?
Thanks in advance!
(Device is running winCE 5.0)

Hi,

I am having problems activating USB client after a suspend resume.
Does anyone has a list of corrections that must be done to the code
that
is release in the latest Windows CE 5.0 Mainstone III BSP Update?

Thanks.

Zico
