Re: Baking Pi

Wow, fast reply! 8pm here. NO output to screen, either for HDMI or for AV mode. Main machine here = mint debian. Keyboard #1 = wireless iPazzPort kbd/mousepad. Ok, so it might have been the wireless side being a problem. So kbd#2 = stock cheap usb wired keyboard. But still no luck. I still need to c...

Re: Baking Pi

Brilliant stuff. But confirm that "input" kernel image gives no keyboard to screen for me either. I'm using latest rpi-update booting files. Also using "sdhci-bcm2708.sync_after_dma=0 dwc_otg.fiq_fix_enable=1 dwc_otg.speed=1" just in case those might be relevant. But I just noticed the MAKE process ...

Re: USB - the Elephant in our Room

... Add another 34 minutes testing a few USB devices. So far: it's hard to make sense. Some stuff works, some doesn't. But this version performs differently than before. Seems to baulk at various things on 7-port hub (4+4). That 5370 wifi likes only to sit right on the pi port (not hub), despite the...

Re: USB - the Elephant in our Room

Well, 4 minutes of testing: (it's 8AM here) 1. No external hub. 2. Wireless keyboard/mousepad in one slot. 3. Wifi 5370 dongle in other slot. (Woops - lsusb -v reports 450mA max !!!) 4. Nothing on lan port. Previously an impossible combo. Should be an illegal (450mA) arrangement also. NOW IT WORKS. ...

Re: Adding RAM to Pi

I seem to recall my original machine came with 4 kB. The upgrade to 16kB was wonderful, even extravagant. A full fit-out to 64 seemed over the top and too much expense. <music here ...>

Re: USB - the Elephant in our Room

Hmmm, Could that be what happened to my 3.5" HDD (a spare one, not with my life documents on it!!)? Last week it spent the night sleeping in bed with the rpi, and it was found dead next morning. Quite beyond recovery. It was still rotating, but no computer (rpi, i86 linux, or windows) would recognis...

Re: USB - the Elephant in our Room

In which case the most pointed question next is:
Is the problem locked away on the pi's hardware, or might it be solvable on SD loaded code? :?:

Re: in stock for next working day delivery

Ordered pi 25 July at Element14 (AU). Delivered 1 Aug into regional Queensland Australia. And I think they delayed a few days for a mouse backorder to send with my replacement pi. I think the drought is over. btw - I found that you CAN brick a pi. :cry: Try feeding the 5.0 volts direct to the GPIO p...

Re: USB - the Elephant in our Room

If it were true (and so far it is a long way from proven, only suggested as a possibility) that the pi usb issues arose only (mainly?) if V1.1 low speed devices or V1.1 any speed were being used, then to be able to simply state that , would be one step towards (1) avoiding frustrations (2) tracking...

Re: USB - the Elephant in our Room

Hmmm, I see that USB V2.0 mouses and keyboards ARE out there. All the ones in my place happen to be V1.1. (Even my cute new iPazzPort tiny combo wireless kbd/mouse is USB V1.1 / 1.5M). So is anyone out there with both 1.1 and 2.0 available, able to test if THAT makes a difference to adding other USB...

Re: USB - the Elephant in our Room

I've been following a hunch (for which some clues have appeared on these forums earlier). I have been trying to keep all USB V1.1 devices off my pi. Both 12M and 1.5M speeds. Trying to use only USB2.0 (480M speed). But hold on. Keyboards and mouses are USB V1.1 (usually?? always??). They are hard to...

We now have had many thousands of PI in the hands of competent enthusiasts for some weeks or even months. Progress on the early bugs and shortfalls has been amazing. 1. SD Cards. The Pi could not read some SD cards (the better ones ironically) - either properly or at all. That seems now solved on ne...
