I did "resume", look at the log below but after rebooting and connecting the windows mashine by Tera Term I have no message on it. I used it before and it worked alright.
Also I tried it on Ubuntu but:
root@stockalerts:~# modprobe usbserial
FATAL: Module usbserial not found.
root@stockalerts:~# modprobe ftdi_sio vendor=0x9e88 product=0x9e8f
root@stockalerts:~# telnet localhost 4444
Connected to localhost.
