Hi, i have a problem with driver for my usb modems. Time after time server stuck( log from this event is below), in this case server has to be rebooted. I think that this could be caused by any condition that cannot be occured. Can you take a look for it or give me some tips to solve this problem? Name of modemes is GlobeTrotter GI1505 and the whole description is in attached in mail. The version of my kernel is 3.6.11 on debian linux. If you want to know any information about hardware or anythink alse, please tell me.
