I want to run a printer in another room in my house WITHOUT networking. My needs require a direction USB connection. Will I have trouble running a USB beyond a certain length of cabling?

  • \$\begingroup\$ This is close to off topic, but the general question of how long a USB cable can be is very useful for any EE that is running into issues. I am not closing this as a very good question for USB. I would like the answer accepted to have references. \$\endgroup\$ – Kortuk Apr 21 '11 at 21:29

I have used a 15' USB extension cable successfully to bring my printer to the oposite side of my office. Beyond that you can get a USB repeater cable

5m is the maximum officially supported cable length, and you can chain several cables using at most five hubs, which gets you at most 30m.

  • \$\begingroup\$ So once I hit 5m, I can use a powered hub and get another 5m (per output on the hub) up to 30m (per chain) with identical performance to a single 5m cable? \$\endgroup\$ – Brian David Berman Apr 22 '11 at 0:04
  • \$\begingroup\$ Only every other hub needs to be powered. There are even 10m cables with a hub in the middle. The performance shouldn't depend on cable length. \$\endgroup\$ – starblue Apr 22 '11 at 6:41
