Hello all, I am using a USB Hub (NXP's ISP1520) on our custom board based on DM6446, for communication with a Windows PC. I tried the GadgetFs configuration (with the kernel module and a userspace driver usb.c to communicate to the endpoints) that is available on the internet.
There was a problem that the Windows was not recognizing the USB Hub; my hardware team removed the 'I2C option' of configuring the Hub. Then Windows detected the hub and the functions (like a Mass storage device or the mobile phone) I connected to the hub. I booted the board with the right kernel, insmod'd the gadgetfs.ko, and ran this driver (usb.c) on DM6446 which is also a function connected to this hub. But it wasn't recognizing the processor. I ran the same driver on the same kernel on DM6446 evaluation board (that does not have a hub), the windows PC was able to recognize the Processor and I was able to communicate with the Windows PC. Can anybody please let me know, what I am missing here with the hub? Thanks, Gopal Sukumar. ________________________________ http://www.mindtree.com/email/disclaimer.html
