RPi 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 the Raspberry 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 Raspberry Pi through their interconnect cable, due to the 100 mA limiting fuse in the Raspberry Pi, the Raspberry Pi will be partially powered which may cause problems (unwanted writes to the SD card).
Raspberry Pi Specific Hubs
Recently, two new hubs have been designed and manufactured specifically for the Raspberry Pi. Guaranteed to provide no back power to the unit. These are
- Raspberry Pi 7 Port USB Hub from The Pi Hut

- USB 2.0 hub 4 port (ACME) Based on NEC μPD720114 USB2.0 Hub Controller USB ID 0409:005a NOTE! It is bus-powered hub, but it is 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 Raspberry Pi, and additionally connect GND and +5 V from power supply to the same holes on USB-hub GND and V. Now there is common contacts: GND, D+ and D- between Raspberry Pi and hub needed to work, and additional power for USB devices, connected to the hub. Tested on my Raspberry Pi.

Problem USB Hubs
Please check known workarounds here before adding to the list
- 7-Port Powered Hub - labelled ADDUH070P - Gives constant Eth0 errors on boot.
- 7-Port Powered Mobile Hub - device labelled F4U018, packaging labelled F5U701. lsusb reveals it to be two Genesys Logic 4-port hubs based on the GL850G chipset (vendor: 0x05e3 product: 0x0608) ganged together. Yields a lot of "handle_hc_chhltd_intr_dma:: XactErr without NYET/NAK/ACK" errors and device resets in /var/log/messages. Low speed devices such as keyboards work OK, Wi-Fi/mass storage is unreliable or broken. -- No error messages with the latest kernel, but it is still unstable with mass storage devices. Also, leaks current back to the Raspberry Pi (can be fixed by overtaping GND and +5 V pinouts)
- F4U022 7-Port powered USB hub (powered 5 V, 2.6 A), same as F4U018
- 7-Port Powered Hub - device labled F5U237 Rev.3 - ID 050d:0237 Wired Ethernet fails to connect; gives "DWC OTG HCD URB enqueue failed adding QTD. Error status -4008" Result is same as DUB-H7 below.
- F5U404 Hi-Speed USB 2.0 4-Port Mobile Hub. Faulty/bad design; Leaks current back up the cable to the Raspberry Pi.
- F5U307 Hi-Speed USB 2.0 7-Port Hub (Powered, able to apply power to Raspberry Pi via micro USB from this hub at same time) It work's sometimes. (Works always without powering the Raspberry Pi, haven't tried that)
- Dell U2410 Monitor Built-in 4 Port Hub - Shows up as a pair with 0424:2514 and 0424:2640. Standard Microsystems Corp. USB 2.0 Hub. When connecting some devices it kills the Ethernet with "smsc95xx 1-1.1:1.0: eth0: Failed to read register index 0x0000011X" errors. It did work for a keyboard and webcam. Bluetooth that works connected directly to the Raspberry Pi triggers the error.
- 7-Port USB Hub UH-713 Rev 3. This one consists also of two 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUBs connected together. The power supply is rated at 5 V 2 A. It kills Ethernet when X11 is started.
- 4-Port USB Hub, no special designator. Chip inside is a GL850G, lsusb identification is 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB. The hub comes with a 5V 2A PSU that is quite capable of powering the Raspberry Pi and additional peripherals. I did not test whether the hub feeds power into the uplink USB port. The problem with this hub is that USB sticks connected to it reliably disconnect after a short time of writing to them (via cat /dev/zero > /dev/<stick>). Sometimes they reconnect with a different device, sometimes they do not. The only error messages in the logs are plain vanilla USB device disconnects. While this may look like a power-issue, measurements with a digital oscilloscope found absolutely no problem. Another observation I have made is that sometimes (not always), the data-transfer rates to the USB sticks slow down to about 500kB/s. I suspect this is a problem with the USB driver that does not manage to work around some brokeness in the hub chip. The hub has no current-limiter at all and plugging in some peripherals will hard crash your Raspberry Pi, something I do not observe with better hubs.
- 7-Port USB Hub - Does not work in Debian 19-04 image.
- DX-HB7PT 7-Port USB Hub - As per the Gear Head below, it's 2 daisy-chained Genesys Logic 05e3:0608 devices. Appears to result in significant slow downs when the USB is under load, such as running the root file system from a USB drive.
- 7-Port USB 2.0 Hub (Silver and black). Feeds power back up the interconnect to the Raspberry Pi causing the power LED to light on the Raspberry Pi if the hub is powered on, but the Raspberry Pi is not. The Raspberry Pi also fails to boot when powered off this hub, with or without the interconnect plugged in. Stops the network from working when connected to the Raspberry Pi after booting the Raspberry Pi - cannot ssh to the Raspberry Pi. Best avoided. :-( Shows up in lsusb as a pair of ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB which is interesting. - Confirmed. This hub also appears unable to power an external USB drive using a y-cable as it gives the error -71 message in dmesg (when providing external power to the Raspberry Pi).
- 4-Port High-Speed USB 2.0 Hub (USB-H40-A2.0), came with with a 1 A power supply. Leaks power to the Raspberry Pi through the uplink.

As of 2012-08-16 Wheezy, if any USB 1.x device (a keyboard, for example) is plugged into this hub, Ethernet stops, and USB interrupts for other devices get dropped (keys repeating forever), etc. Occurs even if power is not attached (not a power leakage problem).Appears working after a bootloader and/or firmware update on 9/12. Also, turned out to be somewhat more specific to the combination of two particular low-speed devices.
- 4-Port USB 2.0 "bus hub", model 78496 (?). Only works for low power devices (card readers?), but it does not work for power hungry devices (HDD and WLAN). It doesn't boot when hub connected to Raspberry Pi. The funniest thing is that Raspberry Pi powers on when I plug in this hub to normal size USB port (not that small dedicated port). idVendor=05e3, idProduct=0608

- Unbranded / Multiple Brands
- 7-port silver/black hub. Also sold elsewhere under brands such as 'EX-Pro', 'Trixes' and 'Xentra' -- This is probably due to an inadequate power supply. -- I replaced the terrible power supply with a very good one, kept getting "DEBUG: handle_hc_chhltd_intr_dma:: XactErr without NYET/NAK/ACK" in dmesg, with no devices plugged in to the hub (with or without the power supply in). Measurements by TrevorGowen (talk) of the power loading behaviour of an example of this type of hub and its supplied PSU are logged at CPM-Spectre-Pi...PoweredUSBHubs, together with similar measurements of other devices.
- Generic 7-port black hub with Genesys Logic GL850A chipset
- Cerulian 10 Port USB 2.0 Top Loading Hub with 2 A supply (kills mouse and network port)
- USB 2.0 4 PORT INT/EXT DUAL HUB BAY -- Genesys Chipset -- idVendor=05e3, idProduct=0607 -- low speed devices worked, but there are strange USB failures when X session started. High speed devices such as hard drives had failures.
