Hi,

I have a memory stick which made problems (the stick is used as a ZFS cache and it moaned about 8xxM write problems) in 9-current r214509. I removed the device from the config, made a camcontrol reset all, camcontrol rescan all (-> device disappeared), and then tried an usbconfig reset ugen4.2 (relevant devlist part from before the call is below). The usbconfig reset does not return to the shell.

I do not know if the problem with the USB memory stick is related to software or hardware. The stick survived just a weekend, I replaced it because the old one showed similar problems after surviving about 9 months... I updated -current just before the problems appeared (and then again after a week or two), but I do not remember from which revision of -current I was updating from. I will try to stress-test the memory sticks on a 8.1 system so see if it is some software problem.

The big question I have for now is: shouldn't there be some kind of safety mechanism kicking in (timeout) with the usbconfig command (in this case the reset)?
