Despite active signal amplification there in my case with the additional use of a USB 2.0 Sharing Switch for Printers is a connection problem, because my assumption after here though the Singal, but too little current at switch arrives to appeal to the sharing switch (switch). This problem occurs only in so far as the only hanging on active cable PC is booted alone, you receive a second PC is turned on (normal = recently USB cable) to the switch and turned on dranhängt there are no problems. With direct connection to the printer (without a switch between) the addressed problem occurs also not on.
