Hi HPS, Thanks for replying. We never saw this issue with previous versions of Freebsd (FreeBSD 6.x & FreeBSD 7.x) booted on the same hardware system. But with FreeBSD 8 we can reproduce it in 3-4 hours. Does this make case 1 more likely? Should below quirks resolve the issue in either case? I will give it a try anyway :)=20 Thanks, Vishal -----Original Message----- From: Hans Petter Selasky [mailto:hselasky@c2i.net]=20 Sent: Thursday, November 10, 2011 12:29 AM To: freebsd-usb@freebsd.org Cc: Shah, Vishal; Ranaweera, Samantha Subject: Re: usb_alloc_device: Failure selecting configuration index 0:USB_ERR_TIMEOUT, port 1, addr 2 (ignored) On Thursday 10 November 2011 05:08:30 Shah, Vishal wrote: > usb_alloc_device: Failure selecting configuration index=20 > 0:USB_ERR_TIMEOUT, port 1, addr 2 (ignored)\r\r\n Hi, The set config message is sent on the control endpoint. The set config message doesn't have any data stage, so the USB stack is waiting for the status stage callback. Either that is caused by: 1) Lost interrupt on EHCI or 2) Device never sends the status stage (needs a bus analyzer for this). Quirks you can set in /boot/loader.conf: hw.usb.ehci.lostintrbug: 0 hw.usb.ehci.iaadbug: 0 --HPS
