Re: Why is USB WiFi device support so poor?

I've had some problems with cheap USB hubs in the past. I now use a couple of these from Mod My Pi. http://www.modmypi.com/raspberry-pi/accessories/usb-hubs/new-link-4-port-usb-hub-uk-5v-2a/?search=Hub Which are standards compliant and come with a proper power supply rated at 2A which is correct for...

Re: Why is USB WiFi device support so poor?

The one question that springs to mind is, was the adaptor correct for the usb hub? My hub, not a Belkin, runs it a 5v 2a power adaptor. Can you still check yours to see what volts and amps it's putting out? I suspect, but obviously cannot say for sure, that it should be 5v. Thankfully, you, and your...

Re: Why is USB WiFi device support so poor?

There seems to be a message at timing 2.957622 stating insufficient power to use a device during the initialization of the USB hub. That would explain why the device isn't working if it is the WiFi adapter that there isn't enough power for, but it still leaves a question mark over why the drivers a...

Re: Why is USB WiFi device support so poor?

Greetings kutuup, are you running Jessie or Wheezy? In other words, which Raspbian are you running please? Much of what you need is different between the two versions. Not Raspbian's fault, it came from Debian changes. Have you updated to the most recent release of your current version? sudo apt-get...

I have indeed run the Main Menu Editor and the option is ticked there. Rebooting has no effect. ...

Re: Cannot set static IP address.

Evening. I'm not sure that you need the network line. I don't have it in mine. Also, in some books, Web sites etc, the various parameter lines are indented one tab and sometimes in upper case, although I don't think uppercase is strictly necessary. The tab might be - mine has tabs before address, ne...

I have run Update and upgrade, but not dist-upgrade, after a fresh install of the Raspbian download. I did not use NOOBS this time.

Hi klricks, Rubikwizard, Leafpad? Interesting. Did you do a full install of Jessie from a Raspbian image, or from a NOOBS image? Mine was from the Raspbian image. On two pis, and both defaulted to Writer, definitely not Leafpad, which is a GUI editor I quite like. I've never installed Libreoffice Of...

Re: Slight Difference between Wheezy and Jessie spi drivers

Evening,

I think this breaks RasPiDuino as well. Under Wheezy everything worked. Under Jessie, I get verification errors all the time. I'm reverting back to Wheezy on Monday and retesting to be 100% sure that it's Jesse.

Norm.

Morning Steve, I've put a fresh download onto another SD, and I see it does not include PulseAudio. Watch out for sudo apt-get update && sudo apt-get upgrade because I think that puts PulseAudio back in! It looks like just adding "hdmi_drive=2" to the Config.txt file has enabled hdmi audio.

Re: sudo amixer troubles - started recently

...So if you want to change some soundcard control, you have to specify it with the -c argument like: amixer -c 0 cset numid=3 'n'. Useful, thanks. On my Pi, card 0 was the PCM one, and PulseAudio was card 1. (I'm 99% sure of that) But either way, your suggestion is excellent. I might even reinstal...

This is true. If you are not in the audio group, you must use sudo. If you are in the group, you don;t have to.

Thanks KenT, removing pulseaudio did indeed solve the problem. I can redirect sound again.

Re: sudo amixer troubles - started recently

Hi Mambono5,

as your Pi is new, I suspect you might need to run the

Code: Select all

sudo alsamixer
command and use the up arrow to set
the master volume and/or unmute.

HTH.
