Hi Laurent, Thanks for your reply.
Most of the modules of the new product(based on Kernrel 2.6.10) are completed, except for the USB module. Hence we have to work with the kernrel 2.6.10 even for USB module. We integrated cmp2usb project into Kernel 2.6.10, and with some modifications and compiled the kernel successfully. When pendrive is inserted into the USB port we are facing the below mentioned problems. (sorry for a lengthy posting) We would be thankful if you / anyone could suggest us with some solution or idea or an alternative approach. Given below is the Console Output CASE 1: When pendrive is inserted "Directly to USB port of the 8272ADS board". CASE 2: When pendrive is inserted on an "External hub which is conntected to USB port of 8272ADS board". Output from console: CASE 1: Pendrive Directly connected to uSB port of the 8272ADS board USB Universal Host Controller Interface driver v2.2 Registering platform device 'mpc82xx-hcd.3'.
