hi,
i am new to linux as well as usb,which i am using in one of my project.
I am having LPC3250 board,which i have configured in Host mode,using the menuconfig(linux kerenl 2.6.34).When i am attaching a USB device to the usb port,the device is getting detected which i am think based on my below observation
1.USB led blinking
2.In the linux ported on lpc3250 board file system when i am using this command mdev -s , sda is appearing in the dev directory
But when i try to mount the usb using this command mount /dev/sda1 /media1
it is giving this problem as mentioned below
