While USB devices are detected at boot, I noticed that usbd won't get noticed of insert/remove events. I tried to play with an UMAX 2200 and one USB memory stick it's always the same thing: detected at boot, then once usbd is started in debug mode I see attach notifications in the logs but after that no other event will occur. I also noticed that the hub I use won't be powered anymore once the last USB device has been removed. I also tried without the hub, it's always the same story. I created a kernel with USB_DEBUG and set level to 10 for all oids in order to figure out what is wrong. The only interesting thing I noticed is that once some usb device is removed, the USB driver enters something that looks like an endless loop. Of course, I may be wrong: I'm really clueless about kernel internals. Any idea ? Thanks.
