connected with arduino nano...giving error of "osc did not start"..
also run board_qc sketch it is showing following error:
Circuits At Home 2011
USB Host Shield Quality Control Routine
Reading REVISION register... Die revision invalid. Value returned: 00
Unrecoverable error - test halted!!
0x55 pattern is transmitted via SPI
Press RESET to restart test
also tried with external power supply of 5 v ,1 amp to the VBUS but same error..also tried connecting D7 to MAX_RESET But no luck...I think USB is not initializing?
is my usb host shield fried?or need to give attempts of more experiments ?
I had maybe a similar problem on my Uno, and my mouse wasn't working on it. I unplugged shield and plugged it again, but with more force. And it works. Try this, if you didn't do it before.
The USB host mini board is very handy and works well. But it works only with 3.3V logic levels so the nano must also use 3.3V logic levels. For example, SparkFun Pro Micros are available in 5V/16MHz and 3.3V/8MHz versions. I have never used a nano so I am not sure what is available.
The mini board VBUS defaults to 3.3V which most USB devices cannot use. Be sure to cut the VBUS to 3.3V trace before connecting 5V to VBUS. Failing to cut the trace will damange the board. The circuits@home website has lots more details.
The board is designed to match the pin out of an Arduino Pro Mini so connecting to a nano should just be a matter of routing signals to the correct pins.
