+# USB Suspend (Firmware issue)
+Currently usb suspend is not working, instead of suspend firmware will reboot. If we are lucky,
+firmware will set device to lo power mode and reboot on resume.
+
+# USB reset (Firmware issue)
+Currently usb reset is not correctly working with some usb host controllers.  
+In some cases it will have absolutely no issue. For example with most xHCI controllers.  
+On EHCI we can be rebooted:
+* Firmware should do some thing if we get reset interrupt. This will solve reset issue for most EHCI controllers
+* Some EHCI controllers will send suspend signal after reset (Hardware bug?). In this case we should ignore suspend interrupt or find correct way to respond on reset, if FUSB200 support it.
