Re: Design flaw? Polyfuses for USB current limiting

Interesting. Personally I am not convinced that there is any design flaw as such. Using polyfuses for protecting the USB is I believe a fairly common practice. There are, however; several issues that need thinking about the PSU being a significant one, but there are also others just as relevant. I t...

Re: Pi compatible WIfi adaptor

Hi Thunder__X,

If you type the command "lsusb" you should get a list of connect USB devices and it should give some idea of what your device actually is. Would be useful to know.

I have been using one now for a couple of weeks and have seen no problems. This adapter uses a Realtek RTL8188CUS. Details f...

Re: using a powered usb port to power a RPi

This reduced the voltage drop through the cable by 0.2 volts. I have now got my HDMI TV and connected that. With my original configu...

You need a cable wth a microUSB connector.<br/> <br/> Everything you need to know about USB connectors can be found here - <URL url="http://en.wikipedia.org/wiki/U.....connectors">http://en.wikipedia.org/wiki/U.....connectors...

Re: using a powered usb port to power a RPi

A quick addition to my previous post.

The wireless hub I'm using is the N150 version Maplin order code N47HW as I noticed there are a couple of Micronet wireless USB adapters available.

A cheap keyboard and mouse I think I got from Asda are plugged into the hub. A Micronet Wi...
