The following reply was made to PR usb/140160; it has been noted by GNATS. From: Mark Duller <mark.duller@oerc.ox.ac.uk> To: bug-followup@FreeBSD.org, jamesbrandongooch@gmail.com Cc: Subject: Re: usb/140160: USB ports are no longer "active" after ACPI suspend/resume cycle. Date: Wed, 02 Dec 2009 09:50:55 +0000 I have seen a similar issue on my x61s Thinkpad while following the 8.0x releases. The behaviour has changed throughout the releases. On my latest test (on FreeBSD 8.0-PRERELEASE #2: i386), I found this issue only occurs if I suspend the system while no usb modules are loaded. On a resume, if one then loads the usb modules (such as umass ehci uhci), usb does not work. My current workaround is to ensure I load the modules I need before the first suspend. A resume in this case does keep the usb ports 'active'. I'll report back if i notice any change in 8.0-Release.
