Powered USB Hubs
A number of low-cost powered USB hubs are known to have caused problems. Members
of the Raspberry Pi forums have reported low power or no power at all in some cases.
The following is a list of specific Powered USB Hubs which appear to be fault-free.
Please note that these do not take into account powering the Raspberry Pi from the hub,
in addition to its peripherals.
If you use a powered hub and PI PSU together consider powering them from the same
power bar with switch, so you can turn them on simultaneously., especially if the HUB
tries to feed the PI through their interconnect cable, due to the 100mA limiting fuse in the
PI the PI will be partially powered which may cause problems (unwanted writes to the
SD card).
Working USB Hubs
▪ Acme
▪ USB 2.0 hub 4 port (ACME (http://www.acme.eu/en-us/product/
019188) ) Based on NEC μPD720114 USB2.0 Hub Controller USB ID
0409:005a NOTE! It is bus-powered hub, but very cheap and small and
works after a small modding: on usb-hub board you have 4 holes: V, D+,
D- and GND. Connect GND, D+ and D- to the RasPI, and additionally
connect GND and +5v from power supply to the same holes on usb-hub
GND and V. Now there is common contacts: GND, D+ and D- between
RasPI and hub needed to work, and additional power for USB devices,
connected to the hub. Tested on my RasPI.
▪ Belkin
▪ F4U040 4-Port Ultra-Slim Desktop hub (powered 5v, 2.6A, lsusb lists as
Genesys Logic 05e3:0608)
▪ F5U224 4 port powered USB hub
▪ F5U231/F5U234 Hi-speed USB 2.0 Tertrahub - 4 port powered USB
hub (verified.. able to power Raspberry Pi using micro USB directly
from hub)
▪ F5U237 7 Port powered USB 2.0 5V 3.8A (5 back port 2 top ports)
▪ F5U259-ME USB 2.0 7-Port Hub (Powered, able to apply power to
Raspberry Pi via micro USB from this hub at same time)
▪ F5U403 USB 2.-0 4 Port Hub (Powered, suspect see F5U404 in nonworking,
didn't test power the RPi from hub.)
▪ F5U700 USB 2.0 7-Port Hub (Powered, able to power Raspberry Pi via
micro USB directly from hub)
