Bug #290
Updated by Hammel over 10 years ago
PiBox Media Server (and related packages) needs to support the following USB devices: # Wifi dongle # Bluetooth 4.0 dongle # 2 Media sticks It should also optionally support: # Keyboard # Mouse If you have all of them together you need 6 ports. But you can do without 2 media sticks during setup and just have the two dongles, keyboard and mouse. That's four port. The RPi only has two ports. The wifi and bluetooth don't need to be readily accessible (but should be accessible enough to be replaceable). The 2 media sticks must be user accessible. This means 2 ports internal to the PiBox Media Server (and related packages) and 2 ports external. The USB ports of the RPi may be able to support low power devices but its unclear of 4 USB devices, including mouse and keyboard, are possible without using a powered hub. There are some off-the-shelf options: # "DSI Smart Hub USB 1.1 High Speed 4-Port Hub":http://www.amazon.com/DSI-Smart-High-Speed-4-Port/dp/B000ZD3XYC - ~ $5US # "HIGH-SPEED USB 7-PORT HUB POWERED +AC ADAPTER CABLE":http://www.ebay.com/itm/HIGH-SPEED-USB-7-PORT-HUB-POWERED-AC-ADAPTER-CABLE-/221264418264 - ~$15 # "Raspberry Pi - 4 USB Hub & RTC - Lite Board":http://www.pridopia.co.uk/pi-usb-4hub-rtc-lite2.html (shield board for RPi) - ~$50US # "UUGear 7 port hub":http://www.uugear.com/portfolio/high-speed-7-port-usb-hub-for-raspberry-pi/ - ~$30 There are some schematics that might help in building these devices. # "USB bus powered hub - more than 100 mA per device?":http://electronics.stackexchange.com/questions/31347/usb-bus-powered-hub-more-than-100-ma-per-device # "Default Simple 2-port USB 2.0 Hub":http://forum.allaboutcircuits.com/showthread.php?t=72097 # "Four port USB hub":http://www.instructables.com/id/Four-port-USB-hub/ (and "TUSB2036 Datasheet":http://www.ti.com/product/tusb2036) # "Google images of USB schematics":https://www.google.com/search?q=diy+usb+hub+schematic&client=firefox-a&sa=X&rls=org.mozilla:en-US:official&tbm=isch&tbo=u&source=univ&ei=e_ocU8iiCor_qwGh94DYCA&ved=0CCQQsAQ&biw=1914&bih=904#facrc=_&imgdii=_&imgrc=RDpNSTLlGdIjRM%253A%3BJEuEt2nOKjPiAM%3Bhttp%253A%252F%252Fi.stack.imgur.com%252F4aOFE.png%3Bhttp%253A%252F%252Felectronics.stackexchange.com%252Fquestions%252F31347%252Fusb-bus-powered-hub-more-than-100-ma-per-device%3B665%3B576 And some writeups of how to mod USB hubs to power the Pi: # "My Raspberry Pi setup":http://fedev.blogspot.com/2012/08/my-raspberry-pi-setup.html # "Review: UUGear 7 port hub":http://www.recantha.co.uk/blog/?p=7928 - might be perfect solution
