IP connection to usb

I connected (anywhere usb / 2) with a printmaker (Epson PP-100II).
Rg45 network connection (IP) USB output on the Epson.
The problem is when I want to burn a CD about 20% printmaker rejects cd (disc error).
If I connect a USB key on (anywhere usb / 2) the data is copied to the key.
If I make a test without (anywhere usb / 2) it works normally, the recorder goes up to 100%.
Someone would have an idea.
Thank you for your help.
