Hi, We are facing some problems with the USB core driver of Linux Kernel 2.6.10. We are using the Linux kernel for MIPS32 architecture running with a CPU frequency of 125 Mhz. The Linux Kernel 2.6.10 is compiled with "kernal pre-emption" enabled. After booting the compiled kernel along with the usb driver loaded, when we connect a USB device for ex: keyboard. we got the message specified below. # usb 1-1: new low speed USB device using ohci and address 2 usb 1-1: Product: USB MULTIMEDIA KEYBOARD usb 1-1: Manufacturer: DARFON usb 1-1: khubd timed out on ep0out usb 1-1: can't set config #1, error -145 usb 1-1: new low speed USB device using ohci and address 3 usb 1-1: unable to read config index 0 descriptor/start usb 1-1: can't read configurations, error -71
# With the pre-emption disabled, the device gets detected and works well with that driver. Is there any reason why the kernel behaves this way? Is there a possible solution for the above mentioned problem?
