I received the device in the mail today and tested it. My experience echoes yours exactly, except that I didn't actually try to use the device after resuming it. I presume you have tried and it doesn't work? Anyway, the story is this. As far as usbcore is concerned, the device _appears_ to work fine. It suspends and resumes okay. The device status fetch done by finish_port_resume() succeeds. The HID driver resubmits its interrupt URB, and the device sends back NAKs. But the power LED doesn't turn back on. The device behaves precisely the same regardless of whether it is connected to an Intel UHCI, a VIA UHCI, or an NEC OHCI controller. This really does appear to be a bug in the device. Maybe it wants some special command before it will wake up fully... but a reset works just as well. This looks like a prime candidate for a quirks entry. I will create one later on. And I'll mail the device back early next week. Alan Stern ------------------------------------------------------------------------- Using Tomcat but need to do more?
