Fedora 17, KDE, and USB Disks – a Workaround!

Adventures With Linux ™ Posted on May 28, 2012 by RGMay 28, 2012

After recently upgrading from Fedora 16 to 17, I found that USB disk mounts in KDE were failing: Could not mount the following device An unspecified error has occurred Not Authorized I finally found a workaround at http://www.suurmeijer.net, and I have slightly modified it: Edit /usr/share/polkit-1/actions/org.freedesktop.udisks.policy as follows:   <action id=”org.freedesktop.udisks.filesystem-mount”> <description>Mount a device</description> <description xml:lang=”da”>Montér en … Continue reading →

Back to 3.3.x

Adventures With Linux ™ Posted on May 24, 2012 by RGMay 24, 2012

3.4.0 was running OK, but then got a whole lot of … BUG…  Bad RSS Counter…  errors, and USB devices stopped working correctly  (after plugging in ‘tethered’ phone, when network went down) So…  Back to 3.3..on my main system…   For the time being..

More Pi Hub Failures…

Adventures With Linux ™ Posted on May 23, 2012 by RGMay 23, 2012

Now I have tried with (according to the wiki..) known/good power supply (Nokia) and – allegedly good – hub (Logik) and am getting the same errors, and disconnect of the USB Ethernet connection.. usb 1-1.2: new high speed USB device number 24 using dwc_otg usb 1-1.2: New USB device found, idVendor=05e3, idProduct=0608 usb 1-1.2: New USB device … Continue reading →

3.4 Released..

Adventures With Linux ™ Posted on May 21, 2012 by RGMay 21, 2012

Kernel 3.4.0 just released…   Not on kernel.org yet, so downloaded from github (https://github.com/torvalds/linux). The latest version of the NVIDIA linux drivers (295.53) already supports kernel 3.4x, and the latest ‘weltall‘ patch for VMware (8.0.3) also supports this kernel version, so should be good to go.. Now – to see what’s new/improved/fixed/broken! Update:   compiled/installed, and everything seems to … Continue reading →

Fedora Upgrade – 16 to 17..

Adventures With Linux ™ Posted on May 18, 2012 by RGMay 18, 2012

After all the Pi excitement, back to (relative) normality.. I upgraded my main (x86_64) systems to Fedora 17, using YUM, as usual..    I have found that using the DVD is messy, and sometimes leaves the system in a ‘hybrid’ state, and then the DVD versions of many packages need to be updated, in any case! Compared to … Continue reading →

Pi Power and Hub – It’s All About the Power Supply??.

Adventures With Linux ™ Posted on May 17, 2012 by RGMay 17, 2012

After many fruitless attempts to cobble together a working USB hub setup for the Raspberry Pi, I came to the conclusion – after trying all the USB/mains power adapters I had (from various phones and other accessories), that the power supply made a significant difference to the behaviour of the Pi..     With some adapters, I had to … Continue reading →

Pi – USB – The Saga Continues..

Adventures With Linux ™ Posted on May 15, 2012 by RGMay 15, 2012

Thought I would try a couple more options, just in case.. First, I confirmed that the USB sound card works connected directly to one of the Pi USB ports (using a USB extension cable): usb 1-1.2: new full speed USB device number 13 using dwc_otg usb 1-1.2: New USB device found, idVendor=0d8c, idProduct=000c usb 1-1.2: New USB … Continue reading →

The Pi / Hub / Power Saga – Running with Scissors..

Adventures With Linux ™ Posted on May 15, 2012 by RGMay 15, 2012

Another option I just tried turned nasty very quickly…    I wondered what would happen if all external USB devices were connected via the (powered) hub, but the answer was soon apparent: usb 1-1.3.1.1: reset low speed USB device number 6 using dwc_otg usb 1-1.3.1.2: reset full speed USB device number 7 using dwc_otg INFO:: periodic_channel_available: Total channels: … Continue reading →

Pi – Near-Death Experience…

Adventures With Linux ™ Posted on May 15, 2012 by RGMay 15, 2012

My Raspberry Pi had been behaving itself on the ‘hardware’ side since I took possession of it, weeks ago.    After reading about limitations of USB connectivity, I obtained a reasonably-priced powered USB hub, with the intention (not surprisingly!) of connecting more things – including testing the possibility of USB sound.. So….  I connected the USB hub, and … Continue reading →

GPU Snake-Oil?

Adventures With Linux ™ Posted on May 9, 2012 by RGMay 9, 2012

Not Linux-related this time…    I should confess that I actually do use Windows 7 frequently, for HD Video processing and editing using Sony Vegas Pro and Cineform (on a stand-alone system), and for colour slide restoration using Photoshop (Win7 on VMware, on Linux)..    The reason is that – simply – there is no equivalent quality software available … Continue reading →
