I have now discovered what changes when the five minute delay is up. As mentioned before, the modem takes 5 minutes before it creates the /tty/USB? devices. Somehow, the modem changes its identity after being plugged in for 5 minutes. When the modem is first plugged in, this is what is created in /proc/bus/usb/devices: T: Bus=04 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 3 Spd=12 MxCh= 0 D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=1410 ProdID=5010 Rev= 0.00 S: Manufacturer=Novatel Wireless Inc.

This is the point at which the modem begins working and the /tty/USB? devices are created. I put this same modem on a machine running Centos 5 and found the exact same behaviour, though I have to use a modprobe command to make it recognize the modem on Centos 5 (modprobe usbserial vendor=0x1410 product=0x4100) and the modprobe is not required to make it recognize the modem on Fedora 10. The product id changes in the same way in /proc/bus/usb/devices, after the same five minute wait. https://bugzilla.redhat.com/show_bug.cgi?id=473166 -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com DRY CLEANER BUSINESS FOR SALE ~ http://www.canadadrycleanerforsale.com -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
