The following reply was made to PR usb/115400; it has been noted by GNATS. From: Garrett Wollman <wollman@hergotha.csail.mit.edu> To: freebsd-gnats-submit@freebsd.org Cc: Subject: Re: usb/115400: [ehci] Problem with EHCI on ASUS M2N4-SLI Date: Fri, 10 Aug 2007 18:23:12 -0400 (EDT) >Old Synopsis: Problem with EHCI on ASUS M2N4-SLI >New Synopsis: [ehci] Problem with EHCI on ASUS M2N4-SLI Sorry to tag along here, but I feel the need to note that EHCI has *never* worked for me, on any hardware platform. On my 6.2 machines, attempting to use a USB 2.0 mass-storage device reliably results in a CPU reset (presumably by way of a triple fault). The symptoms were the same in 5.x. The only workaround I've found has been to compile a custom kernel without the ehci driver, but it would be nice if this worked some day. FWIW, these are all AMD machines, and the symptoms are the same on VIA (ASUS A8V), NVIDIA (ASUS A8N-E), and SIS (Acer Aspire 5002) chipsets. The machine with the NVIDIA chipset runs in 32-bit mode, and replaced an earlier ASUS A7something with a VIA chipset and the same symptoms. -GAWollman
