Does with happen with any USB device? I ask, because its consistent with a problem with ACPI, in that a device might not be re-activated correctly as the system comes back up, causing all sorts of possible problems. Having to shut the machine off would make sense in this case. Now, if you know that plugging a specific usb device in before didn't cause this problem, you know this isn't the problem. But if these are new devices, there might be a problem. --STeve Andre' _______________________________________________ Thinkpad mailing list [email protected] http://stderr.org/cgi-bin/mailman/listinfo/thinkpad
