What is the correct procedure to do a Device Remote Wakeup from SS, HS, FS? I see flags in the API document telling me if they are enabled. However, I would like to wakeup the host when I get certain interrupts on the device side. The closest thing I can find is CyU3PUsbSetLinkPowerState

The next revision of the SDK will have APIs for this.

Any update on this? Is there any way for me to test this out? I really need to get this working as my deadline is coming up.

You can the test build of the FX3 SDK from:
ftp://dbfcust:Cust5rvc@ftp.cypress.com/fx3/USB_TEST/FX3_SDK_B789.msiCust5rvc@ftp.cypress.com/fx3/USB_TEST/FX3_SDK_B789.msi
Installing the MSI will require uninstall of the previous SDK (and maybe the Eclipse and ARM GCC as well if they used the full installer previously). If this is not acceptable, all of the files in the release can be obtained from the ZIP file below:
ftp://dbfcust:Cust5rvc@ftp.cypress.com/fx3/USB_TEST/FX3_SDK_B789.zipCust5rvc@ftp.cypress.com/fx3/USB_TEST/FX3_SDK_B789.zip
Both of these links are publicly accessible and can be used directly. Please go through the release notes (change log and known problems sections) before starting to use the new SDK.

In SDK1.1.1, there is a new USB API called CyU3PUsbDoRemoteWakeup() to cause FX3 to perform
USB 2.0 remote wakeup signaling.

I am testing this routine and I am always getting a 0xFF status back which has the meaning below. I have RWU enabled in the descriptor, and before calling this function, I am also doing a SetFeature Remote Wakeup command. Any ideas?
CY_U3P_ERROR_OPERN_DISABLED = 0xFF /* The requested feature / operation is not enabled in current configuration. */
Also, how do I detect if RWU have been called? In the future, I would like to read a varaible to determine if the SetFeature request as been called.
