I upgraded the firmware on my USBConnect 881 and was able to connect to the network using the Jaunty Jackalope Network Manager default settings for the AT&T provider. Here's /var/log/messages logging from plugging in the device to connecting to the network: {{{ May 18 08:46:32 nusadua kernel: [ 2213.232060] usb 2-1: new full speed USB device using ohci_hcd and address 4 May 18 08:46:32 nusadua kernel: [ 2213.478151] usb 2-1: configuration #1 chosen from 1 choice May 18 08:46:32 nusadua kernel: [ 2213.519859] usb-storage: probe of 2-1:1.0 failed with error -5 May 18 08:46:32 nusadua kernel: [ 2213.568099] usb 2-1: USB disconnect, address 4 May 18 08:46:34 nusadua kernel: [ 2215.090250] usb 2-1: new full speed USB device using ohci_hcd and address 5 May 18 08:46:34 nusadua kernel: [ 2215.331312] usb 2-1: configuration #1 chosen from 1 choice May 18 08:46:34 nusadua kernel: [ 2215.332648] sierra 2-1:1.0: Sierra USB modem converter detected May 18 08:46:34 nusadua kernel: [ 2215.334632] usb 2-1: Sierra USB modem converter now attached to ttyUSB0 May 18 08:46:34 nusadua kernel: [ 2215.334721] usb 2-1: Sierra USB modem converter now attached to ttyUSB1 May 18 08:46:34 nusadua kernel: [ 2215.334795] usb 2-1: Sierra USB modem converter now attached to ttyUSB2 May 18 08:47:03 nusadua pppd[5859]: Plugin /usr/lib/pppd/2.4.4/nm-pppd-plugin.so loaded.
