Slow keyboard mapping<br />

If you have remapped your keyboard and get a very long delay during the keyboard<br />

mapping at startup, type the following once on the command line after you have logged<br />

in:<br />

sudo setupcon<br />

No USB device works, with known good PS, <strong>SD</strong> card, KB<br />

There has been more than one report [13][14][15] of a R-Pi booting but not getting USB<br />

input, using a known-good power supply, <strong>SD</strong> card, and keyboard. The more common<br />

cause for no USB devices working is low power supply voltage from bad PSU, cable, or<br />

USB hub, but in this case the problem was no clock signal present at the LAN9512 USB/<br />

Ethernet chip "IC3", and the solution was to reflow the solder on the 25 MHz crystal<br />

"X1" on the bottom side of the board. Or return the board for a replacement, but before<br />

making this conclusion, confirm known good peripherals. A significant number of USB<br />

keyboards are not compatible with R-Pi. As of June 1 2012, Eben reported [16] that only<br />

about 1 in 1000 shipped R-Pi boards have been found to have a hardware fault of any<br />

kind.<br />

Updating firmware<br />

Check your firmware version<br />

Using the latest firmware version may help various problems with <strong>SD</strong> card and display<br />

compatibility. Check the kernel version with:<br />

uname -a<br />

Linux <strong>RPi</strong> 3.1.19 #1 PREEMPT Fri Jun 1 14:16:38 CEST 2012 armv6l GNU/Linux<br />

And the GPU firmware with:<br />

/opt/vc/bin/vcgencmd version<br />
