--- Comment #3 from Derik Barseghian <[email protected]> 2011-04-20 14:07:15 PDT --- The prolific dongle dies too, in a similar fashion - at a certain point dmesg shows errors and you can no longer use it without a system restart. I tried simply reloading the pl2303 and usbserial modules, but no luck, lsusb -v will still include an error for the dongle: cannot read device status, Connection timed out (110) dmesg: ------ usb 1-1: cr1k_d timed out on ep0out len=0/0 usb 1-1: cr1k_d timed out on ep0out len=0/0 usb 1-1: cr1k_d timed out on ep0in len=0/7 and later: usb 1-1: lsusb timed out on ep0in len=0/255 usb 1-1: usbfs: USBDEVFS_CONTROL failed cmd lsusb rqt 128 rq 6 len 255 ret -110 ------ Now I've changed: /sys/bus/usb/devices/usb1/power/level (MUSB HDRC host driver) /sys/bus/usb/devices/usb2/power/level (OMAP-EHCI Host Controller) from auto to on, to disable autosuspend, in case something has a problem resuming after suspension. /sys/bus/usb/devices/1-1/power/level (the USB-Serial Controller) was already on. Let's see if this helps. Other things yet to try: a keyspan dongle, ubuntu upgrade, connecting dongle through a powered usb hub (though this wouldn't be ideal). -- Configure bugmail: http://bugzilla.ecoinformatics.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ Kepler-dev mailing list [email protected] http://lists.nceas.ucsb.edu/kepler/mailman/listinfo/kepler-dev
