That ^^ looks good (and normal) > Sep 23 04:32:59 mefi kernel: [ 4269.262526] usb 2-1.7: reset full speed > USB device using ehci_hcd and address 5 That ^^ doesn't - either it's a coincidence, or it may be the problem. I've seen this in two situations:- ; older kernel loading uhci and ehci in the wrong sequence - temporarily solved by unloading those modules and reloading in various orders until fixed. Permanently fixed by upgrading to the latest kernel for the Debian release ; legacy USB device support turned on in (some) BIOS. It appears that a (your 3G device) USB device is being reset... Try plugging in your device, waiting until "dmesg | tail" shows the modem has been detected and the /dev/ttyUSB* nodes have been corrected - then:- # cat /dev/ttyUSB0 You should get some chatter about signal quality etc - it you get "device not found" (or similar - I'm going from memory) then the problem is the usb module being unloaded (conflicting modules). You might also try another USB port. <snipped> > > This is the screenshot: > http://www.opentek.biz/berkas/mykppp-hangup.on.starting.pppd.jpeg Which prompts me to ask (again) - which *Debian* release are you running there?? :-) Also - who is your ISP, what make and model is your modem, and is it a prepaid plan? <snipped> Cheers -- "As if growing wasn't hard enough - I had a genius for an older brother.
