Hi, I am using MCB2300 (mounted with LPC2387) which i want to act as USB Host for USB Pen Drive. I tried downloading the example code of http://www.keil.com/support/man/docs/rlarm/rlarm_fs_ex_msd.htm. but it says "Drive not connected, please connect it ..." . I observed, that USB pen drive is not powered up when it is connected to MCB2300 eval kit. The LED on it lights up when connected to PC. Please guide me, do i need to enable any thing in software or change any sought of jumper settings on eval board.
Hi, Please ignore my previous reply. I tried to change the hardware as mentioned in your reply except the jumper between P1.31 and P1.27. as when i connected this jumper, my code behaves in an abnormal way. Nothing is getting displayed on LCD. So i left that jumper unconnected. But still there is no difference. The output still says the Drive is not connected, please connect it and the light on USB pen drive is also not glowing. To enable the USB power supply, I tried to pull down the LM3526 enable pin(P1.19) by configuring it as IO pin and then setting the pin direction as Output and then clearing P1.19. But still it didn't helped. I am stuck at this status where, i have done the jumper connections on the pads around the micro-controller, loaded the modified software, but still the output says Drive not connected, please connect it.
Require your help to diagnose the problem, please help.
