Re: USB bus seems to be shutting down after 30seconds

Looks perfect to me, it doesn't say how long the cable is nor the output voltage, but I assume it'd be 5v.

The quality of the USB cable is the only real unknown.

Re: USB bus seems to be shutting down after 30seconds

No one has wodnered if the main reservoir cap (electrolytic) might be leaky or high ESR. (even though it shouldn't be being SMD)

Re: Visual Studio and C#

I don't know what would need to be done, but GHI Electronics with their NXP Arm 7 boards use C# as the programming language.

I have their PandaII board but haven't played with it much yet.

I can't give you the exact time as I always make my own order number thereby wiping out the E-14 generated one (which has time and date format). It was between 6 a.m and 6:10 amm though.

Re: Delivery soon in Australia!

Element 14's Australian website doesn't have the same layout or information as Farnell UK, it just shows my order, status and order number. The actual Pi page is still showing 143 days.

Re: To the inventor of the rasberry pi.

I'm a little confused with this thread, I can't work out if a serial number exists or not, if it doesn't one useful purpose for one is tracking if a bad batch of components make it into production, boards and batches can then be matched if necessary.
