Hi,
Thanks for looking into this, and that sounds more positive. So does that mean in principle that if we poke the various registers directly, we should be able to get the U device to transition from AWAKE to ASLEEP and back again by following the USB bus' suspend state?
Thanks,
CD

Re: XS1-U12: Usb suspend/standby/sleep
Hi, Thanks for the answer, but that doesn’t quite make sense! The datasheet for the XS1-U12A-128-FB217 (2015-04-14) clearly states that “A transition from the ASLEEP state into the AWAKE state is instigated by a wakeup request triggered by a request from the USB block to exit standby mode an input, ...

Re: XTCP DHCP Behaviour
Hi Louis, Thanks for the replies and sorry about the delay in following up. Yes, I guess that a different DHCP server could behave differently and work out that the DHCPDISCOVER is from a device with a valid IP address. If you unplug and re-plug the Ethernet cable, so you see the xTCP code send a DH...

XTCP DHCP Behaviour
We’re using the xTCP library V3.2.1 and have come across an issue with the DHCP behaviour. We get the occasional “port flap” where the Ethernet link goes down briefly, which can also be simulated by unplugging the network cable for a short time. In this situation, the DHCP behaviour seems incorrect,...
