Double-check that this sum plus the drop across the 5 resistor (measured between pin powered 1 and 4 patch cord wires of the type A output plug) equals the bench power supply voltage.
Can be used for powering PI only when it is not mains connected to the PI as USB root node.
Does not work even with a powered x86 Linux box.Weight: 29g (net weight without any accessory).The models before it demanded a slightly lower 5V at 1A, powered however in practice greater amperage was advisable.High speed devices such as hard drives had failures.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).It has the added benefit of connecting your Pi to the internet at the same time, using special injectors.(Ethernet failed, slow response, in lxde.The user manual 1 says Per Port Current Self-Powered Mode: 500mA (max).Contra the report under "Problem Hubs" below, I do raspberry powered not have any trouble with wired ethernet on a Model B mains pi,.x linux kernel. Measured.07 V with 5 devices attached (mouse, keyboard, wlan stick, audio stick, memory stick).
