Hello, Am not an active Linux developer. I wanted a clarification regarding a usb structure. Please let me know if I should address this question in a different forum. I have a problem compiling a usb driver code. The existing code includes /usr/src/linux/drivers/usb/core/hcd.h which defines usb_hcd structure. The driver code refers to hcd_priv member of usb_hcd structure. But the .h file present in the kernel versions, 2.6.5-7.201-smp & 2.6.5-7.244-smp do not have 'hcd_priv' in the 'usb_hcd' structure. Please let me know if this structure has undergone any changes. Is this member removed from the later versions of SLES 9 ? Thanks, Aparna.
