I certainly don't want to rain on anyone's parade, as I have been and continue following this thread with great interest and am grateful for info that's been posted here, but what it hasn't covered quite so much ground on is that whole pros and cons thing...DavidS wrote:We are showing a huge Pro:

Yes and not finding any thread about another complete well supported OS that goes into as much detail as seems to be common on the RISC OS forum here at raspberrypi.org. I have not seen anywhere that they talk about the architecture of the Linux or BSD kernel, or the strange archetecture of the X server, etc.... Though yet in many of the threads on RISC OS these things are descused in some level of detail. You could probably compose a reasonable refference from the topics on this RISC OS forum.tufty wrote:<steps back and looks at the majority of content on the forum>DavidS wrote:We are showing a huge Pro:

Sounds about right - they did it with RAM size and front side bus speed, CD rom units and hard drive capacities. Funny thing is if you run (even) Windows 3.1 on a 486 66mhz machine it seems really fecking fast compared to a more modern machine.rurwin wrote:..I expect processor cores to multiply by two every eighteen months from now on..
Is your keyboard attached DIRECTLY to the Pi or does it go via a USB Hub?chocolate wrote:This is my favorite OS for the Raspberry PI.
When insert text in a text-box (on Netsurf), the keyboard would keep on imputing the same character until I press a random key. - Again, its another temporary con.
Don't worry -the more feedback the better (and I'd rather if you've experienced something different to hear about it !)Markodius wrote:Not that you were asking me..
It's weird alright - because given that I can't see any pattern to it, do you ?Markodius wrote: but.. mine does it thru the hub and when attached directly. Oddly, it almost never happens when I'm overclocked and absolutely never on Raspbian.
There's something a bit "variable" about all of this. I can run RISC OS (at stock speed I may add) using the keyboard that comes with the Maplin "RaspberryPi" kit (and a 512MB Pi) with no issue *except* when I connect it to the supplied Hub rather than the Pi itself.Markodius wrote:Yes - I too would have thought that overclocking would exacerbate the issue - but at stock speed with my keyboard RISCOS is near to unuseable missing many keypresses and repeating others until another key is pressed. I'm told that purchasing a cheaper keyboard will likely fix it completely - but I use Raspbian for a desktop at the moment and until I get another pi for RISCOS it's of no moment to me at the moment (..hah!) I hate the feel of cheap keyboards though. At the risk of making myself look foolish (no great risk really) I can only guess that RISCOS is too strict in what it expects and when from a keyboard as it's a very tight OS in terms of how long things take. Other OS's vary somewhat more in how long any given task will take. That's my two pennorth! In DavidS we trust!
I don't own a USB hub. I have it directly connected to the PI. It's a rare occurrence.AMcS wrote:Is your keyboard attached DIRECTLY to the Pi or does it go via a USB Hub?chocolate wrote:This is my favorite OS for the Raspberry PI.

I found when typing in commands (at the BASIC command line - as simple and as undemanding an activity as you can get) that sometimes (randomly) the same character would repeat a few times... but only when attached via a HUB. If I plugged the same keyboard directly into the RPi the problem went away and simply doesn't happen.
Probably not, actually. There is an issue with utilisation that was discussed in the ACM journal just a while back (vol 56 no.2) that makes it look like we have a problem coming pretty soon. They suggest that over 35 cores is unlikely to work and we will get there within 10 years.rurwin wrote:

Odd. I have the exact same setup as you—with the keyboard and mouse connected via the hub—and have had NO problems with RISC OS. I've had (very rare) problems with Raspbian, when I had a flash drive plugged in to the hub—since removing the wi-fi adapter (which doesn't work in RISC OS anyway) I've had no further problems. Suspect that perhaps the power supply *to the hub* perhaps wasn't giving enough power on occasions, but don't really know.AMcS wrote:There's something a bit "variable" about all of this.

One would expect an identical set up to behave, how shall it put it, identically - but clearly it doesn't (or I've missed something).dr_d_gee wrote:Odd.

I've had similar problems with a cheap "optionally-powered" hub on Windows XP. If a WiFi adapter was plugged in, the USB drive didn't work, even with the hub powered. I'd say your analysis was correct.dr_d_gee wrote:since removing the wi-fi adapter (which doesn't work in RISC OS anyway) I've had no further problems.

Well, I have the Maplin keyboard and mouse, and sometimes a USB stick, connected to the hub; only the hub itself is connected to the Pi. I do have an ethernet cable connected, and use the Maplin power supply.AMcS wrote: One would expect an identical set up to behave, how shall it put it, identically - but clearly it doesn't (or I've missed something).
To fully list devices attached and OS version might help "eliminate" possible causes from our enquiries (if there's anything you use that I don't or visa versa that might suggest something):
My Pi runs RO 5.19 RC6 (it is 512MB but NOT a Hynix memory model), both CPU clock and memory speeds are at their defaults.
It has two devices attached to the board USB - the Maplin keyboard and the Maplin supplied HUB.
The hub has the mouse and (from time to time) a USB stick attached.
I run the Pi off an LG power adaptor rather than the Maplin one (for no particular reason).
I am NOT using the Ethernet connector (note this too internally - as I understand it - comes via the PI internal USB interface - so that may be another part of the puzzle to be considered).
Thing is the keyboard NEVER malfunctions when plugged into the PI USB port - it frequently does when plugged in via the USB HUB. Which seem to run counter to your experience. As both experiences are true I am at a loss to account for this.
Thanks again for that. I think this is one of those cases where one has to be pragmatic - whatever works works. For some it'll mean attaching the keyboard direct to the Pi for others via a powered hub.dr_d_gee wrote: Well, I have the Maplin keyboard and mouse, and sometimes a USB stick, connected to the hub; only the hub itself is connected to the Pi.
