?? That is the way all USB "Y" cables work? AFAIK there is no other way they could work.mahjongg wrote: you need one that loops the power through from two ports, but the data-lines from just one.
I've not done any soldering before - is there a way to parallel the fuses without soldering? If they both use one fuse, how much power would each port receive?mahjongg wrote:For bridging the fuses you do NOT have to take off the connector, and there are two ways to do it:
Paralleling the fuses, so both USB ports share two fuses that are paralleled, is done by simply connecting pins 5 of both USB ports together. see the picture below The other method is simply soldering a wire across the fuse, simple to do an can be removed in a minute. F1 is the fuse for the upper port, so you can simply only bridge the "high power port", and let the other fuse alone, so you can use it with a low power device.
Personally I am not too keen on taking a soldering iron to my new Pi, or on cutting leads etc. unless really necessary, so am thinking of using a Masterplug SRGDU42PB USB Extension Lead Power Block with 4 Sockets, (http://www.amazon.co.uk/gp/product/B006HFME4C) which incorporates two USB power sockets, said to provide 1000ma output (which I assume is per socket?). One of these would be used to power the Pi, and the other a powered USB hub which would be a Newlink NLUSB2-224P. (http://www.kenable.co.uk/product_info.p ... ts_id=5614)mahjongg wrote:..... OR you need to power the PI from the same hub (if the hub can power the PI reliably from a single one of its ports) so the PI and hub are powered from the same single 5V source.
For those in the UK, a very similar option, which has just been mentioned in another thread at http://www.raspberrypi.org/phpBB3/viewt ... =46&t=8556 is available from Currys/Dixons for just £3.97 One of the 3 USB outputs is 1 amp, so a 'Y' cable may not be necessary, assuming of course that the voltage is OK.b455x wrote:another possibility would be such a device:

(sorry, german amazon homepage...)
it's a PSU with two USB ports - you could use one to power your pi and another one to power one part of an Y-cable
the other part of the y-cable would of course go into the usb-port of the pi...and the single end would connect with the wifi-stick or whatever device that needs more power...
that's just a solution if you do not want to use a powered hub...it's still one psu and the stick is connected to the pi, just with one cable more...
No need for any soldering, nor cutting, just stick a bit of cello-tape on pin 1 of the USB connector, connecting the hub to the RPI.Montala wrote:Personally I am not too keen on taking a soldering iron to my new Pi, or on cutting leads etc. unless really necessary,
