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 →
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 →
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 →
I had intended to persevere with the Fedora 14 ‘respin’, despite it being (correctly, IMHO..) described as ‘a bit buggy’.. Performance was improved with the newer 3.1.9+ kernel image, without the debug messages, but overall the response was still very sluggish.. I selected XFCE as the UI, as I had used this – successfully – with Fedora … Continue reading →
Found the latest kernel image (still 3.1.9-based..) and associated pre-compiled modules at the git repository – https://github.com/raspberrypi/firmware – and the ‘new’ version of kernel.img does away with the annoying console debug messages.. Device still seems very slow, but maybe I’m too used to quad-core systems with masses of memory! I even tried the Debian system, as this … Continue reading →
Tried to join the Element14 ‘Programming-the-Pi’ Webinar this afternoon (April 4th), but although the java app started OK, all I saw was an ‘info’ window, and myself showing as the sole attendee! Tried with Firefox and then Chrome, but no joy… Maybe the Cisco Webex stuff they are using doesn’t work with Linux? (Oh, the irony…) (”Webinar” … Continue reading →
The Linux kernel source for the Pi has been ‘forked’, rather than being released as a patch set.. This is probably a necessary evil, in order to get a working version out in public… But.. This has the (obvious) downside that we have to rely on regular creation of ‘newer’ forked versions, and the current Pi kernel … Continue reading →
