▪ Addon
▪ 7-Port Powered Hub - labelled ADDUH070P - Gives constant Eth0 errors on
boot.
▪ Belkin
▪ 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, wifi/mass storage is unreliable or broken. -- No error messages with the
latest kernel, but still unstable with mass storage devices. Also, leaks current back
to the Pi (can be fixed by overtaping GND and +5V pinouts)

▪ 7-Port Powered Hub - device labled F5U237 Rev.3 - ID 050d:0237 Wired
