I did some followup on another machine at my disposal running a Debian 2.6.32-5-686-bigmem on the same hardware as the Ubuntu box - Dell Poweredge T110 II I plugged Digi in and had the same response as with the Ubuntu box - io_edgeport was not loaded/no new devices/same dmesg report. Then I manually loaded io_edgeport and plugged the Digi in again. dmesg (after manual load) is a bit different than with Ubuntu: [29735001.555230] usb 2-1.6: new full speed USB device using ehci_hcd and address 65 [29735001.647709] usb 2-1.6: New USB device found, idVendor=1608, idProduct=0288 [29735001.647713] usb 2-1.6: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [29735001.647788] usb 2-1.6: configuration #1 chosen from 1 choice [29735001.647964] hub 2-1.6:1.0: USB hub found [29735001.648148] hub 2-1.6:1.0: 1 port detected [29735001.918939] usb 2-1.6.1: new full speed USB device using ehci_hcd and address 66 [29735002.017518] usb 2-1.6.1: New USB device found, idVendor=1608, idProduct=0202 [29735002.017522] usb 2-1.6.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [29735002.017600] usb 2-1.6.1: configuration #1 chosen from 1 choice Could it be that Digi has changed something that is causing the problem? Digi info: Model: Edgeport/4r (your website lists Edgeport/4i as supported - not 4r) could this be the problem?
