Sorry, I just noticed this, the power supply you got isn't powering the Pi, but the usb hub? What else is drawing power from the hub? Also, is the pi plugged into a single USB port, or are you using a "Y" cable?pa3fat wrote:Powersupply came via RS together with the PI. States 1,2A.
All powered via the USB hub and (just checked) still up.
Not sure if it is absolutely stable. USB also included and did notice a drop. But now on other port of the hub and let's see.
Will check the indicated voltage at the regulator later.
As long as it keeps working, I guess don't worry about it, but if you keep having problems it's possible that the single USB port can't supply enough current to the PI. Also, and this is probably a needless warning, keep in mind that as you add things to the HUB you're lowering the available amount of current to the PI. Assuming your keyboard dongle takes ~200 mA that still leaves you with 1A for the pi (which is ample), but that really means you only have 300 mA to spare and anything you connect to the hub that draws more than that current will drop the available current for the pi into possibly unstable levels (though you should gain some mA back since you're not using the built in USB ports to power anything) just stuff to keep in mindpa3fat wrote:One slot on the USB Hub is used to power the PI via the regular micro USB slot
The fixed USB cable on the HUB is in one of the slots of the PI
The Keyboard USB dongle is in one of the remaining slots of the USB HUB
Checked again and...... still running
1) What's the power rating of your PSU?Loriano wrote:I am having the same problem, it keeps crashing (freezing) and only active light is the red one. Running Raspbmc, one USB keyboard connected to one of the USB slots and the HDMI cable connected to the monitor. 2GB SD Card.
1) What's the power rating of your PSU?
I have two, one says Max. 0.1A Output: DC 5.2 580mA and the other one says Output: DC5.0V + - 5% MAX: 1000mA MiIN: 150mA and it crashes with both.
5) What are you doing when it crashes?
It loads Raspbmc and if I select any of the options (Weather, Videos, Pictures etc...) it freezes, only red LED on. No response from keyboard.
Since you have the 0-ohm resistors instead of the 140mA fuses you could theoretically power a hub from your pi, the only thing to keep in mind is that you would need a bigger PSU to meet the increased demands from the usb portsLoriano wrote:Any suggestions on self powered USB hub or will anyone do?
there is a temperature sensor and you can query it but there is no hwmon driver that Xbmc can read, not yet that is, soon: http://www.raspberrypi.org/phpBB3/viewt ... 26#p169726pa3fat wrote:Not sure but if i remember correctly XBMC is not showing any temperature reading in the systems overview. So i doubt if there is any sensor available.
