Comment 28 for bug 373821

Finally I continued with: complete removal of rc7, full 9.04 update (update manager), shut down, MF636 attached, boot. The ZTEMODEM drive not shown. Within dmesg I found "usb-storage: device ignored". Stated as 19d2 : 2000 at lsusb. A removal/reinsertion gives:

[ 323.366334] usb 1-3: USB disconnect, address 2
[ 665.596104] usb 1-3: new high speed USB device using ehci_hcd and address 5
[ 665.742371] usb 1-3: configuration #1 chosen from 1 choice
[ 665.752174] usb-storage: device ignored
[ 699.568006] usb 1-3: USB disconnect, address 5

And then: rc7 installed, shut down, boot with the modem attached, ZTEMODEM shown, wait some seconds, from terminal: dmesg > dmesg_g31.txt (attached)
Eject, wait, dmesg to the terminal window, "new mobile broadband" window opened below terminal window and some seconds later stucked. At the terminal window you can see the loop again: ttyUSB0,1,2 later 1,2,3 etc. (photo at:
