           Summary: Belkin f5u409 usb=>serial dongle periodically stops
                    working
           Product: Kepler
           Version: 2.1.0
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sensor-view
        AssignedTo: barseghian at nceas.ucsb.edu
        ReportedBy: barseghian at nceas.ucsb.edu

Sometimes the Belkin dongle gets in a state where all 3 of its LEDs stay off.
This corresponds with being unable to run cr1k_d over it. I'm not sure if this
is the sole reason for bug#5332, or if that sometimes happens even when the
lights are on.

When this state occurs, and you try to use cr1k_d, dmesg starts showing errors
like:

usb 1-1: cr1k_d timed out on ep0out len=0/1
usb 1-1: Set MODEM CTRL 0xb failed (error = -110)
usb 1-1: cr1k_d timed out on ep0out len=0/1
usb 1-1: Set LINE CTRL 0x3 failed (error = -110)
usb 1-1: cr1k_d timed out on ep0in len=0/1
usb 1-1: Get MODEM STATus failed (error = -110)
usb 1-1: cr1k_d timed out on ep0out len=0/1

I've tried this procedure to see if I could get the dongle working again, but
it didn't work:
lsmod | grep -i usb
sudo rmmod mct_u232; 
lsmod | grep -i usb; 
sudo modprobe mct_u232

Rebooting consistently makes it work again.

Nick recommends trying a Keyspan dongle, and updating from ubuntu 9.04 to 10.04
(new kernel, possible hardware fixes). 
I'll try the dongle he recommends when I get a chance.
