I can not be sure of what I never had 100% results

But I do not see what I could be mistaken here. I wrote in the config ip address of kindle - 192.168.0.20 and ip address of PC - 192.168.0.1. I went into debug mode, start usbnetwork (as I understand it, if there was something wrong before that, I'll had not seen ~ usbnetwork command in the command list when I type ~ help). Then connect Kindle to my pc and it still works as a mass storage device.
Yes, i have run network scaner but in results i saw only my PC address...
But do not pay attention. I think the problem is in erased data ... Seeking a dump

Thank you for caring
